Hi everyone, I am making this thread to share everybody's experience on overclocking the GTX 660m.

I have the G75VW-BBK5 (Best Buy version) and I am more than pleased to tell you that I have reached +135 on the core and +350 on the memory clocks. I did not push the memory any further since I did not wanted it to overheat. The clock is maxed out with +135, I can not push it further, EVGA Precision did not let me go beyond that point. So far it hit only 68 C which is by no mean a terrible temperature. I made the test and taking out the bottom cover so that air can flow directly into fans and GPU temps did not hit 65 C... IMAGINE WHAT YOU CAN DO WITH NO BOTTOM COVER AND A COOLING PAD !!

The moment of truth was 3DMark Vantage where I WAS ABLE TO MAKE 13900 !! This thing overclocks like a beast.

Just thnx for your time in reading this, and leave your experience too !

Someone sent me a PM asking about weather to get the 660m or 670m. Just to clarify this for everyone I post what I told him.

From the experience I'm having with the 660m, so far it has been wonderful. I was able to overclock it up to 1085MHz at the core and it did not show any signs of artifacts or any fail. I would not consider that level a everyday overclock, as such I would use instead 1070MHz or 1065MHz. I only took memory to +350 from base clock but it can go beyond that for sure, I just did not wanted to risk anything (if there is). Without any overclock, 660m gets around 12100/12200 points in 3DMark Vantage (overall score). With the overclock I was able to hit 13900 points which is monster overclock. I think stock 670m gets around 13000 (from what I read). So overclocked 660m passes stock 670m. Nevertheless it as been said that 670m can be overclocked very far achieving 14700/14900 at frequencies I do not know.
On the temperature side my 660m did not overpass 67 C in max overclock... I have heard that 670 gets pretty toasty, I particularly prefer a bit less performance for a less hot card. Remember that 660m is Kepler while 670m is Fermi.

All this I'm saying it in reference to G75, so in G55 you will see less overclock and more temperature. If I had a G55 i would definitely go with the 660m.

Finally I was able to play BF3 in ULTRA with a bit less anti aliasing at 1080p. (around 27/30 fps)
Crysis 2 at HARDCORE with same fps and also 3D capable with no overclock. So imagine around 3 more fps with overclock.
GTA 4 with ENB series tweak, which kills whichever card you have, and got around 26 fps with almost all at HIGH and shadows at very high. This result was overclocked.

Hope it helps. Any other question don't hesitate to ask.

Hi Guido7142,

First off thanks for the information you have provided. I have a couple of questions for you.

What program are you using to overclock?
I am currently using MSI Afterburner and Nvidia Inspector.

You said that you are able to over clock to 1085 MHz. What is it that is being put at that frequency? If I push my core clock up +135 which is the max it looks like I can push it it only reaches 970 MHz

Also how is overclocking with the 301.42 drivers?

I will also be doing various tests with different frequencies and report back my findings with different benchmarks.

Desani

Here is my result with +135 core clock and +300 Memory Clock and 301.42 Drivers

3dMark Vantage : P12880

http://3dmark.com/3dmv/4114212

Do you know why I am off about 1000 from yours?

Guido7142

Hi Desani. First of all, apparently driver 301.42 is stable, I noticed a bit more performance than the factory one.

As regards the core overclock, I must tell you tan the +135 are from 950MHz which is the turbo frequency of the 660m (at least it is in my G75). I don't know if you have a G75 or G55. I have been using EVGA Precision for overclocking all the time. In Precision (latest version which I think is 3.something) you will see kind of a tachometer like the one in your car which marks the core clock. There are two lines shown in that tachometer, a blue one which is the base frequency of the card (835MHz) and an orange one which marks the turbo frequency (950MHz); if you do no overclocking at all, the GPU automatically boosts to 950MHz by it's own when needed (At least in High Performance mode of Power4Hybrid). Whenever you add an overclock to the core, it is summed to the turbo frequency, ex: +10 will take you to turbo frequency of 960MHz.

As regards the difference in score in 3DMark Vantage, I don't know if it affects the benchmark but I have an SSD. Theoretically it would not be any difference. I can post my different stages of overclock with it's respective scores, I have been keeping record of them as I overclocked the GPU.

Keep providing me with your experience so I can help you get that GTX 660m to it's maximum.

I am using the G75VW model with the 660m. I pushed mine to the same limits as yours and I had very similar results. I am not using the full version of 3DMark Vantage though and so it doesn't run as many tests. I think this is the reason why we have a variance.


3DMark Score
12899 3DMarks

Graphics Score
11349
Your Graphics Score was 11278. Very similar

CPU Score
21849
This is where the main difference was. Your score was 50357. I assume this is from different tests?


Jane Nash
33.78 FPS
I assume this is your GPU Test 1 with the result of 33.71

New Calico
32.69 FPS
I also assume that this is your GPU Test 2 with the result of 32.34

Both almost identical.


AI Test
2976 operations/s
I assume this is your CPU Test 1 with the result of 2959.64

Physics Test
30 operations/s
This is where it changes. You have 167.40 for your 2nd CPU test.

Here is a lint to my results.
http://3dmark.com/3dmv/4114331

I really like this program for overclocking and I wasn't aware of the step up in processing power on the GPU.
I had recently bought a g74sx with a 560m graphics processor before this and had to return it and ended up getting this as an upgrade. I had noticed that the 560m had slightly better performance in Skyrim but I do believe that it was due to properly written drivers. I do hope we get some official 301.42+ ones from Nvidia soon.

Still don't know why we get so different CPU scores, don't forget to put it on High Performance mode.

Why did you return the G74 ?

Today I tested Crysis 2 in Extreme settings (only above is ULTRA ) and 1080p and got 28 fps average; with DX11 enabled. This GPU is quite a beast. I would like to give a test to the 670m although... I come from a low end pc and I am always tempted to max out the graphics in everything in this notebook, but I would like to see more of 30 fps and above also by taking things a bit lighter. Don't get me wrong, 660m is incredible, but it can not extremely max out such demanding games like BF3 or Cry2, still gets very close.

What games have you tested so far ?

I returned the G74 against my will. I loved the machine and it had amazing cooling so it could be pushed just as far overclocking wise. I ended having to take it back because it was having some hardware problems where graphics card driver would just crash will browsing the internet and it would not wake up from sleep properly. I would have been happy if it worked. I am, however, really liking the feel of the new G75. I find that it over all has a sleeker feel to it and it feels more refined as a product. The PowerGear Hybrid utility on the G75 I find to look much better.

Here are the games that I have been testing so far to get the best results on my unit. I, like you, like great settings but it also has to be playable.

Skyrim:
Resolution: 1920x1080
Main Setting: Ultra
Special Settings: AA 2x, AF 4x, Shadows High
FPS: 50 - 60 and sometimes around 40 if it is a heavy scene.
Overclocked Status: +135 Core, +375 Memory Clock (Not Required for smooth play)

Crysis:
Resolution: 1920x1080
Main Setting: High, Unplayable at Ultra High
Special Settings: AA 2x
FPS: 35 - 55, Very playable
Overclocked Status: Not Required

Metro 2033:
Resolution: 1920x1080
Main Setting: High, Unplayable at Ultra High
Special Settings: AAA, AF 4X
FPS: 14 - 30, Semi-Playable
Overclocked Status: +135 Core, +375 Memory
Notes: I do think we will see better performance with this game as we see the graphic drivers for this card mature.

Portal 2:
Resolution: 1920x1080
Main Setting: High
Special Settings: AA 8X
FPS: 58 - 60
Overclocked Status: No overclock
Notes: It eats this game for breakfast.

They should be coming soon these days, from what I see at the Asus site they have an upgrade every two months and it's been almost 2 months since the last official one.

If 660m performance goes up I will definitely fall from my chair when seeing new benchmark results.

First of all download the driver version you want from the link I left above. Then you will be led to another site where it says 2 options: 1. Download the solicited driver click on that and download the driver) 2. Download the INF file associated with these driver (you download this too). The extract the driver file you downloaded and inside the folder that comes up you will see another folder called Display Drivers, inside there is the original INF file, replace it for the one you downloaded. Now uninstall the divers you have installed and install the new ones you downloaded.

Any other questions don't hesitate to ask.

1. Go to the link I left in the lasp post.
2. Choose the driver version that you are willing to use (according to you Operating System).
3. When you click on the driver you want another page will appear which says "Click here to download driver and INF files", click it.
4. Another page will appear which says:
- Click here to download the requested driver.
- Click here to download the modified INF file.
5. From those two download the files, both the driver and the INF file.
6. Go to the folder in which you have downloaded the files and extract with WinRar the driver files.
7. Enter the driver folder and then the Display Drivers sub folder, there is the original INF file.
8. Replace the original INF file with the on you have downloaded.
9. Uninstall your currently installed drivers.
10. Install from the driver you downloaded the new drivers.

Hope it helps.

Thanks for the help. I did find the folder "Display Drivers" folder, but there is no INF file in it. The closes file is called " Display Driver.nvi, & Display Driver_1.nvi" are this file the same as the INF file? Or sine there is no INF do I just add the file to it?

I have just checked again the page and it seems you can not download anymore the INF file, you can see its content only. I've searched for the INF file and could not find it in the Display Drivers folder either. The file is not named INF but it's format is ".INF".

I find the file I will tell you, this is strange. When I did this it was quite easy to install :confused:

Thanks, so I was thinking it was little weird that way it was. Well if you find some thing please let us know, by the way the driver I was try to get was 302.59. If there is an other one that work it's welcome as well. The current driver I have is 295.55.

06-07-2012, 07:04 PM
If I find anything I let you know, in either case, I think that nVidia must be releasing their official drivers (when I say official I mean, in their web) soon. These claim to be official but it's is just weird you have to modify a file to get them working.

Guido, thanks for the guide. I dl'd the 302.59 driver and .inf file, and followed your guide. When install checks compatibility, it says files are missing and ends install. I have the 660M in a G75VW. Any ideas?

Guido7142
06-07-2012, 10:53 PM
If it says that it could not verify that the drivers are compatible with your card, then there must have been an error in the INF file step. This INF file prevents this from happening. Check those steps, if you succeed in them you will be able to install the drivers. I really don't know why we have to make this INF replacement for the to work in the 660m, apparently they are not for these cards ?

Hello,
When you have downloaded the 302.59 driver from laptopvideo2go,
follow these stepds:
1. Extract to where to want the files
2. GO to the laptovideo2go page where you downloaded the driver from
3. Click on download the INF file, it will open a new tab
4. Go to you extraced files 302.59_win7x64/Display.Driver go down to find the the nvwi file
5. Open that file
6. Press ctrl+a and delete all the text
7. Go the page with the inf file then copy all that( ctrl+a)
8. Paste all this into your nvwi file.
9. Press save as and click ok.

Anyway, I really wanna break the 3k mark, just that I don't know how to do it since the Core clock is stuck at +135 max..

Guido7142
06-24-2012, 12:52 PM
Is it stable with that +632 in the memory ? I only tried up to +450.

As regards overclock limits, there's a program called Nvidia Inspector that lets you go beyond +135 in core and everything. The problem is that when I tried it, after unlocking the limits, when I set an overclock frequency, nothing happened. I mean, I put for example an overclock of +100 or +135 in the core and when I apply it, it doesn't really work, my frequency still is the base clock. If someone knows something about this please let us know.

I did try overclocking it to a few higher clock speeds and the results did not go well.

I did the +632 Memory clock with the +135 Core and I did get pink discoloration errors followed by a driver crash.

With +550 Memory clock the driver did not crash but I did get some visual distortions. I think the max that my card would like to sit at would be about +525 Memory clock. I am happy with the +500 though. I don't think I will be pushing it much further than that.

Is the GTX 660m more powerful than the GTX670 in the Asus G75?

Guido7142
06-24-2012, 06:21 PM
The 670m is a bit more powerful, but runs a bit hotter and consumes more power. The notebook can still handle very well the temperatures of the 670m. The 660m runs incredibly cool, I've got max temps in Furmak of 67 C even with max overclock, The obly disadvantage of 660m is that has a 128bit memory interface which is a bit thin, I get quite an fps drop in GTA 4 with ENB and custom cars when traffic is crowded. The 670m has 192bit memory interface which will make such thing no so drastic. Otherwise if you go for performance, go with the 670m if you search power efficiency and longer battery life go with 660m.

It was completely stable for me at those speeds, but going any higher on the memory clock produced artifacts. So I was probably at the barrier. Anyway, I think my card lucked out, since Desani's card was getting distortions.

I can go higher however... 500~ gets a few. 600* causes several 607*> causes crash.

Yesterday I tested going further on and reached +135 core +630 memory as max stale. +635 memory gave me little blue artifacts. Even though I noticed that my memory constrains in GTA 4 ENB Mod and custom cars that require lots of VRAM size and speed were reduced. This time it did not dip as much as from +450 memory +135 core. Who would have thought that that extra from +450 to +600 would be so useful.

Incredible. Are such memory overclocks common for the 660m? I've got mine at 250+ Mem and 120+ Core stable on Furmark. It gets to about 68 C max at those clocks and after 12 mins of Furmark, so unless I can make a custom fan profile I will keep those clocks there.

Guido7142
07-14-2012, 11:06 PM
I use +135 and +600 all the time as if it were water. I even use +625 in memory sometimes. Max temp I ever ever got in Furmark was 72 C. Apparently there is no way to custom fan speeds or curves, I've searched everywhere and got nothing.

+Memory doesn't really improve performance on most games by all that much. The core does, and it sucks that the VBOIS limits it to +135.
Do any modders know how to get around this limit? I feel like we can easily beat a GTX 670 if we can unlock the cap and reach the +300s.

so by default the nvidia speeds are 405/2500

does that mean say 460/2700 means +55/+200

I can also fell that this GPU has much more to give but really doubt if it is possible to get +300 as a stable OC...

No, that 405 base clock is something that you can only find in nVidia's web and has no use. Some software such as 3DMark also shows that 405 clock but that is not true.
The actual fact is that the base clock is something around 850MHz, the card itself has a boost clock speed that is set to 950MHz by default (when running intensive games cock automatically goes to 950). Now every time you add +x into the core cock, you are actually adding to the turbo frequency. For example +50 core are actually 950MHz + 50MHz = 1000MHz.

you can reach more than 350 with nvidia inspector I just saw that on nvidia website, take a look.



Hi everyone, I am making this thread to share everybody's experience on overclocking the GTX 660m.

I have the G75VW-BBK5 (Best Buy version) and I am more than pleased to tell you that I have reached +135 on the core and +350 on the memory clocks. I did not push the memory any further since I did not wanted it to overheat. The clock is maxed out with +135, I can not push it further, EVGA Precision did not let me go beyond that point. So far it hit only 68 C which is by no mean a terrible temperature. I made the test and taking out the bottom cover so that air can flow directly into fans and GPU temps did not hit 65 C... IMAGINE WHAT YOU CAN DO WITH NO BOTTOM COVER AND A COOLING PAD !!

The moment of truth was 3DMark Vantage where I WAS ABLE TO MAKE 13900 !! This thing overclocks like a beast.

Just thnx for your time in reading this, and leave your experience too !

On my previous laptop I was able to clock my nVidia with up to 20% and gained 10-12 fps more, it was so cool! I want this happening on my G as well. I wanna crank up my baby and play as its meant to be, I want to get past these miserable +135MHz :(

why is that happening?

Guido7142

I won't go further than that in the mem, I think I also have +500 or something like that. You can push much hard on the core, find the limits of your GPU and then back a bit for safety and there you go.

Guido7142
12-09-2012, 08:44 PM
Yes there is but it is not convenient, you just stress the GPU for nothing when you are browsing internet. I'll explain it in detail tomorrow but just a little explanation, this what is does is to create a file (exe like) which you just open by double clicking it and this triggers the clocks up, then when you are done gaming or whatever you open another file that sets everything back to default (so that the GPU stays cool and under stressed when not necessary). Every time I game I just open that file and clocks jump up and when I'm done, I open the restoration file and everything can rest once again in low clocks.
This file locks the clock in maximum frequency (set by you), instead of using an 'on demand' setting.

A quick easy guide in how to overpass the +135 that you can achieve with any OC program like MSI Afterburner or EVGA Precision is by using Nvidia Inspector. This is a program that enables you to see the different 'states' in which you can put your GPU. These are P5, P8 P0 and maybe another one too. These enable you to go beyond the +135 and unlock the clock of the GPU.
What you have to do is the following. First of all download Nvidia Inspector. Then you have to create a batch file (editable with a notepad) and start playing with those command lines that the link I gave talks about. These force the GPU to do certain things like lock the clock at a given frequency or the memory too. Just a recommendation, do not touch the voltage offset since 6xxm cards auto adjust the voltage to the frequency at which they are running. These batch files allow you to OC, by editing them in a notepad and then just opening them, all those commands execute themselves and voila, OC is done. It may take you a while to find out which of the states really works for you but don't give up, you will eventually find it.
I recommend to have two batch files, one for OC and one to go back to default settings, so as not to stress the GPU when not needed. As I mentioned earlier, you open the batch in which you have the OC lines when you are going to game and then when you are done you execute the back to default batch. Just to clarify, you do not need to have Nvidia Inspector open while using these batch files but the must be placed in the directory in which you have the Nvidia Inspector.

I'm currently using these as a OC batch line (locks clock at 1270):
nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,1270 -setMemoryClock:0,2,3050 -forcepstate:0,0

And these as a default line (back to dynamic clock according to demand):
nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,705 -setMemoryClock:0,2,2500 -forcepstate:0,16

How can we confirm that the core is already been changed? I run the batch...then I check the current core clock on nvidia inspector...the current clock is correct...but when I check on GPUZ ...it does not shown the 1230 core clock that I set...even MSI afterburner not changed anything...only the memory clock is changed...not the core. How can I confirm it?

Guido7142
12-10-2012, 05:48 PM
MSI Afterburnes has the truth, Nvidia Inspector shows clocks that I do not know what they are and GPUZ shows just the info that the VBIOS has about the GPU. When the batch file is applied, then MSI After should show the OC frequency. Maybe the state you are using only ramps up the clock when needed and does not lock it at the highest frequency you specified.

If what you said is true that MSI Afterburner showing the real clocks. You have OCed it to 1270/3050 right. Does your MSI Afterburner showing +435/+550? Just wanna make sure NVIDIA Inspector is bypassing the limit core clock and not just showing numbers. Coz I dun feel much different between 1270/3050 (Batch Settings) and the normal OC I use in MSI Afterburner which is +135/+400 (970/2800).

I'm at a wall on the mem oc.
http://www.3dmark.com/compare/3dmv/4493046/3dmv/4493009

If I go past +552 performance stops going up, at +603 it starts droping below what I get @ lower settings.

One thing that I notice also is that over the course of several tests my CPU scores are inconsistent, usually showing higher when performance scores lower. I'm at a loss on how to proceed.

Guido7142
01-01-2013, 04:36 AM
That inconsistency happens to me too. I did not worry too much, at the beginning I also saw some low scores and then an insanely high score appeared and the once again a bit lower and so on... Never had any problems, as a matter of fact the 3610QM mostly is not likely to be the bottleneck in the G75 so not much to worry.

01-01-2013, 05:49 AM
I agree that the CPU is not a bottle neck, but I do suspect the video mem and possibly the CPU are being volt starved at higher settings. i played around a bit with nvidia inspector and can push clock setting past the P state values, but voltage ? I think this is because it's a laptop and the power management is always active, likely also part of the cooling scheme. I don't know, I am normally a desktop guy.
Not that I am complaining, this thing eats most games without the OC, and gives me just that much more bump with the OC without heat concerns. I just wanted to see how far i can go with it for my own curiosity.

Guido7142
01-01-2013, 03:03 PM
I never thought about that voltage issue, just because it auto adjusts as you OC. But maybe you are right, my 660m never passed the 1.1 V, but still the OC I did was massive.

crimey
01-09-2013, 02:54 PM
hi there!

I just want to know, why my temp is so high!?

I overclocked the 660m with MSI Afterburner, first i benchmarked it with the tool from MSI Afterburner. The result was something about 73C.

Then i increased clock and memory +25

Same result as at stock settings?

But why is my temp so damn high?

And what do u think, can be the highest temp, without damage ...

Guido7142
01-10-2013, 03:30 AM
Mine also gets to 70+ when I get it to almost 1300Hz and the memory in +500Hz. Depends also in the room temperature, if you live in a hot place it might get higher than that, just don't hit 80, that's high. Of course there's people that say 'I always get my GPU to 150 C and nothing has ever happened' but you know... better to be cautious.

itsgreekpete
01-10-2013, 05:03 AM
@ 1290 on the core and 2800 on the memory (artifacts on anything higher) my temps cap at 70 so taht is a little strange because msi doesn't take the core that high... have you checked for dust? what kind of surface is your laptop on? i wouldn't worry about damage the laptop will turn off before you do any damage to it

Guido7142
01-11-2013, 03:32 AM
Don't worry, just turn on the OC when needed and not always. I have just cleaned the fan filters and the heat sink by removing the back plastic cap in which the speakers are and there was quite a bit of dust so temps should improve but nothing major nor worrying. Just clean the filters and blow some air through the fans once in a while and you'll be fine, no need to clean it so intense as I did. Again, just do not overpass 80 C... that is a bit alarming.

Can someone please share their fps boost in BF3 with this method of OC? I tried OC it to 1300 and in Desktop mode its OK, but when I start any game the display driver crashes. Then I tried 1200 and in the beginning it is fine, temps are fine, but after 1h of gameplay it crashes again. And the boost I get from the 1200 is merely 2-5 fps (for the BF3)!

I am sorry for writing to an 660m thread with 670MX on board.

Trying to run Nvidia Inspectur but it shows unhandled error JIT and lots of information. Anyway I tried to run the batch commands for my GTX 670MX and they worked in a way so I was able to push it to 800 MHz on the core.

Can anyone guide me how to properly set the batch commands, the P states forcing as well as whether the batch commands leave permanent mark in the bios or with every restart they go to default?

Thank you.

Ah, nevermind, I followed the link related to the Nvidia Inspector and realized that in my case it is not worth the trouble. Even at 800 Unigine Heaven freezes. I am going to stick to +135 for the moment until I figure out whether it is possible to be playing with the voltage.

There is not any i9 invented yet! But you can try if you can :D And about the upgrade: your current system is using a 45W CPU (the i7 3610QM), It is possible to upgrade, but only with a processor that uses the same power, otherwise you risk having a PSU meltdown :)

did you test it on playing games?whenever I put it to +500 mem, I always get crashes and black screen.

Ha Ha... Yeah with benchmarks maybe they don't test the VRAM that much? Furmark shows only mem load 11%.

With Hawken, playing last night, I had to set it to a more conservative 1085mhz core, 2700 mem. +250 mem causes crashes. So +200 mem is just nice.

On Windows 8 though, the driver just resets, and I can continue playing (have to run the nvinspector bat file to re-overclock after a crash). This is with Hawken.

Surprisingly, FurMark and so on are ok at 1200mhz core, ~3000mhz mem. I think because the VRAM is not tested much.

I think depending on the game I might put it at 1050mhz core, 2700mhz mem. My VRAM in games seems to be a little sensitive, but again I haven't tested it in any other games, just Hawken and Furmark, etc.

In any case +200mhz VRAM is a pretty good overclock. Might depend on ambient temperatures as well.

And core clock from 835mhz to 1085... 250mhz overclock on a laptop! That is still really amazing.

Maybe depending on the game the most stable setting is 100-200mhz more on the core and 100-200mhz more on the VRAM.

Also the CPU definitely works much more so you have lots more heat playing games than say Furmark.

When I run P95 as well as Furmark (yes hoping it doesn't blow up here :)) GPU goes from 70degC stable to now 79decC and rising slightly. CPU at 90degC temps.

So playing a game at these settings with GPU and CPU hitting 80-90degC temps is very, very aggressive. Let alone then seeing stability in games, drivers etc.

But of course for bragging rights saying you can run Furmark with +365mhz GPU core, +500mhz GPU MEM, +150mhz CPU core (3.2ghz max turbo to 3.35ghz) is... fun.

As some people have mentioned, if you take off the bottom cover and use a laptop cooler, keeping temps below 70degC, then it may be possible to have more stability.

It should be noted that ASUS already put in 2500mhz DDR5 VRAM which is much faster than the Nvidia-specified 2000mhz VRAM, so despite the 128-bit bus width, if you're running 2700mhz DDR5 VRAM, that's quite a lot of bandwidth, in fact, not that far behind the GTX 680M at 115.2GB/s ~ at 2700mhz the GTX 660M is doing 2*128*2700/8 = 86.4 GB/s and nicely ahead of Nvidia-spec'ed GTX 660M's 64.0 GB/s.

BTW. Hawken .INI tweaks... It looks AMAZING on GTX 660M overclocked. That 200 or so mhz does help. Will share this sometime on another thread.

Hi all, quick update. With Hawken last night, I was able to go several rounds on GTX 660M core 1085mhz, vram 2700mhz. The few times it crashed was because I was constantly Alt-Tabbing to edit the Hawken ini settings to tweak the graphics. I found something really useful for Hawken settings, especially Prosk map which is really hard on frame rates.

I have a G75vw-bbk5, and i use MSI Afterburner and i OC at +135 Core and +375 Memory, in GW2 i get 60-70 fps in lions arch and dungeons and heavy active places but when im questing or doin chill stuff i can reach 90-95fps. My temp wise has never gone over 64C but i do have bottom cover off and i have a aftermarket gaming cooling fan pad for it.

Very nice. But you can push 660M further especially with your "special" cooling... Like +200mhz core and +500mhz mem. :cool:

I upgraded to get the benefits of the Crysis 3 improvements, etc.
Sadly I lost about 200 MHz of overclocking headroom, does anybody know if this was intentional by NVIDIA?

1250 MHz core really DOES make a difference. Big difference.

In short no, or at least I would not test it on a G55. svl7 has been known to complete requests if you meet the requirements for the forums at tech inferno.

It would need to be the exact same motherboard. If you can confirm that it is, then it would be very likely that this bios would work... I doubt that due to the fact that they have different bios revisions available from the support site for the G75 and the G55.

Uhh unless you have been intentionally ignorant there have been plethora of posts about serious issues with those modded bios files. There is absolutely no reason for me to go and intentionally void my warranty and break my system. Sure it might work out for some but it's just a game of Russian roulette as Asus quietly rolls out revisions and uses chips from different manufacturers during production you never know what issues your going to get when using one from another system. I have no issues with using modded Vbios/bios for my desktop hardware because there is far fewer issues and the community is more experienced in my opinion so don't get me wrong, I have nothing against modded bios files but its clearly evident that the ones posted in the link trieuan10 posted need some more work.

Well we are not all as delusional as you getting butt hurt when someone has a objective view. If you were rational you might take the time to look at also the people who have had many issues with these modded bios files and also understand why they may not work for everyone. Sorry for having an opinion that does not suit you, anyway I'm done talking about it, I respect your opinion and I understand that these modders have done work that people very much appreciate but I'm also not ignorant enough to not acknowledge the issues others have had. Simply disregarding their issues with the mods as user error is not fair to them. After all... it's not exactly rocket science.

That overclock would be fine, you should not get more than 2-3 degrees hotter temperatures at that overclock. You can always use something like HWMonitor to check what kind of temperatures you are getting if you are concerned. You should only be worried if your GPU temperatures go above 80c.

I should changing only GPU and memory clocks or I should also focus on something else?

Generally, overclocking the GPU will give you the greatest performance boost. Personally I would stay away from the CPU because it already has something called turbo boost. In essence turbo boost overclocks the CPU automatically when more performance is needed. You would be hard pressed to see a game utilize all of the CPU's power in the first place so overclocking it will not really be that beneficial unless you like to benchmark your system but for games? no.

The only way to currently overclock your GPU past the +135 core clock limit is to use an older driver like the 310.70 because in the newer ones they fixed the exploit. And once you are using one of the older drivers you can use nvidia inspector and create a batch file to set any overclock you want. If you want to know more about that I suggest reading on this threat from page 5-6 onward. http://rog.asus.com/forum/showthread.php?16367-Overclocking-gtx-660m/page9&highlight=660m It's also possible to unlock the bios/vbios to unlock all limits put in place by Asus.

Overclocking the Ram may give you a bit of a performance boost too but still the GPU is your main focus if you want more FPS. Just remember that you make sure your system is stable at its overclocked state. You can do that by using programs like memtest for the ram, prime95 for the CPU and furmark for the GPU

I hope that helps

Yup, the temperatures are very good, exactly as expected and you got a nice performance increase too. If you wanted you could increase the gpu memory clock a little, that would give you even more performance. And if you want to go past the +135 core clock then you can find the nvidia driver which will allow for the exploit here: http://www.geforce.com/drivers/results/55125

I tested the newest drivers in Tomb Raider without O/C and got 20-35 frames on Ultra with 314.14. Upon dropping back to my current driver and and applying OC i Hit 35-48. So I would have to say no?

However, I do now have the vbios mod, so I can update drivers and maintain the OC ;). So this will happen.

I'm using EVGA Precision X 4.20, Nvidia Inspector 1.9.7.1, and I see the following info:

GeForce GTX 660M
GPU GK107 Revision A2
BIOS 80.07.2C.00.15 [Modified] (No idea why it says Modified, as I haven't done anything I know of.)
Device ID 10DE-0FD4 Subvendor ASUS (1043)
ROPs 16 Shaders 384 Unified
Memory type GDDR5 Bus Width 128 Bit (96.0 GB/s)
Memory size 2048MB Interface PCI-E 3.0 x 16 @ x16 1.1
Driver Version Geforce 320.00 - [r319_00_106]
Temp 37 C Voltage .912v
P-State P8
GPU Load 0% MCU 4% VPU 0%
Current Clock 135MHz Memory 405MHz Est. Max 950MHz
GPU Clock 835MHz Memory 3000MHz Boost 950MHz
Default Clock 835MHz Memory 25000 MHz Boost 950MHz

So as you can see, using:

"C:\Users\Merk Man\Downloads\Nvidia\nvidiaInspector.exe" -setBaseClockOffset:0,0,235 -setMemoryClockOffset:0,0,500 -setVoltageOffset:0,0,0

Does increase my memory MHz, but not the clock. :(

What am I missing? Could I be looking at EVGA Precision incorrectly? I look at the triangles at the center of the "speedometer", but they aren't going up past 135.

It's been a while since I did any overclocking. Is +135 MHz the point where the slider stops? Or is that where you start getting graphical artifacts?

If it's where the Core Clock slider stops, then it doesn't matter what driver you use. It's a limitation set in the BIOS. And even so, the max setting isn't necessarily the fastest. These cards are designed to "throttle" the clock when the card gets to certain temperatures. If I remember correctly, the first throttle is 80 C. If you either hit that temp or begin to see artifacting, your clock speed is above the optimum setting and should be lowered.

Merk Man
06-16-2013, 08:46 PM
Where the slider stops. I saw people indicating with the 320 driver they were about to go beyond 135MHz. So I tried doing the same, but I've had ZERO luck doing it myself. That said, other than trying to get TressFX running at a decent framerate, this laptop can pretty much do anything my other PC's can. Only my desktop with an ATI 7970 can make TressFX it's ***** and it runs crying home to mama. And while I've spent $100 on a Blu-Ray burner, $100 on 16GB of RAM to take it to 24GB, and $330 on a 500GB SSD drive... It was still less than $1500 for a pretty sweet rig.

Hey hopefully someone can help me out.
I overclocked my 660M using NVIDIA Inspector and upped it to 135/500.
However when I loaded up BF3 my fps didn't go up at all. The only thing going up was my temp.
I was wondering how much improvement should I notice?

DirkHardeck
06-21-2013, 03:13 AM
@Mark Man: Neither my AMD nor Nvidia SLI rigs can run at 60+ fps with TressFX :D So yeah, I wouldn't even bother with a laptop really.

@Haze69: Overclocking isn't a catch-all. On some applications at some times, you will certainly notice a difference, other times not so much. Especially if the bottleneck is your cpu, overclocking the gpu won't help. My rule of thumb is that if an oc does not create a clearly noticeable improvement, then I won't bother. At any rate, the 660m is pretty capable with getting a fairly solid 60+ on BF3 at max settings sans MSAA....although depending on your cpu, that could bottleneck as well since BF3 is quite CPU intensive.

I normally scoff at overclocking laptop gpus, too little performance for too much temperature gain and die wear, but I will say that oc'ing the 660m has created about a 8-10 fps increase in many games with a 2-3 degree increase in temperature.....quite a fair tradeoff.

My laptop is in a very cool place and I rarely even hear the fans kick on so heat should not be an issue. I have an Asus G75vw 660M and I see others in this forum say they can run Ultra with 60fps solid and on Youtube as well I am just trying to achieve that.

My performance improved from at least 12000 to 13000 + as you can see

I achieved this performance boost by making the batch files that were mentioned earlier (page 11 I believe) before. The only down side is that my temp pops to 75, is the a stable temp?

After reading further into this forum I must clairfy, I'm a g55 user achieving 1100 core 2750 mem and temp usually rolls up to 68 and into 70's when gaming...

Batch files:
Overclock
nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,1100 -setMemoryClock:0,2,2700 -forcepstate:0,0

Default
nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,835 -setMemoryClock:0,2,2500 -forcepstate:0,16

When I was using nVidia inspector to OC my G55, I managed to get 1300 core and 3100 memory. That was stable, and it did something although not much, it gave me around +5-8 fps in Battlefield 3. I left it like that until I tried playing Diablo 3, and it started lagging as hell. Then I did some research and found out that Diablo 3 doesn't fair well with OC cards. Then I reverted back to stock and I have been like that since. To be quite frank OC will not let you pump up that AA from 4x to 16x because of the OC, but it might let you get the same FPS when you switch from medium to high textures, just saying. I prefer stability over a bit more glitter on the screen that will not make much difference(if at all) in a fast paced game :)

With my oc'd card and my cpu unparked as well as clocked to 3.35 GHz I was able to play BF3 without stuttering and no AA

In my experience 1100mhz core and 3000mhz mem gives great performance, some games I need to drop it to 1050mhz core and like 2950mhz mem. GPU temp was hitting 85degC but in a recent repair they replaced the whole fan assembly so not even going over 75degC when cpu usage is low (testing Blender CUDA GPU rendering now).

No regrets anymore getting my G55. Spent a little bit of cash today to get a Windows 8.1 disc to fresh install etc. Going well.

So I read this thread from first to the last post.
My quest to squeeze more juice out of this Video Card came from only being able playing Far Cry 4 with the lowest settings.

So I've done some testing and I wanted to share some details here.
Based details and instructions shared here, I created 2 bat files and ran against NVidia inspector and tested with FurMark.
OC'ed:
nvidiaInspector.exe -setBaseClockOffset:0,0,135 -setMemoryClockOffset:0,0,0 -setVoltageOffset:0,0,0 -setGpuClock:0,2,1200 -setMemoryClock:0,2,3000 -forcepstate:0,0

Stock:
nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,835 -setMemoryClock:0,2,2500 -forcepstate:0,16

I have an G75VW-DS71, Win7 pro on top of a Samsung EVO SSD.
Ran the 1st set of tests (pre set bench mark 1080), Stock settings was getting 12fps at OC'ed as at 14

2nd set was ran after fresh install of Win8.1 pro
Stock was at 13, OC'ed at 16

Upgrading the O/S alone did increase performance by a bit.
Could someone share their FurMark numbers, to see if what I see are expected numbers based on FurMark preset benchmark 1080

Don't think it matters, but i'm connected via MiniDisplay port to my monitor.



...yes im new here :)

My Furmark is around 800 (13fps) for GTX660M 1100mhz core 3000mhz mem... You have good scores and if stable at 1200mhz that's awesome :)

I see the most benefits of overclocking during gaming, with the latest driver (and game?) settings I can play COD:AW at almost all max settings including SMAA. Looks amazing.

I used the batch files today to OC my gtx660m to 1150core and 2750memory. in Shadow of Middle Earth at high settings it now moves faultlessly, Dragon age Inquisition as well at High settings and Ultra textures. My temps are about 73-78degrees. My question is: IS IT SAFE? :)) i mean i know that 78celsius is a good temp for a card that's playing an intensive game, but still is it safe to OC a card from 835 to 1150core in the long run?

I don't play much games but for 2 years when playing OC'ed (1100mhz core, 3000mhz mem) everything has been fine. Except (luckily within warranty) in the last six months the fan assembly and the power brick had to be replaced :)

Yeah what is amazing with the 660M and Kepler architecture is performance has been really good all this time especially when running OC, you can really crank up the settings.

Suffice to say it pushes the laptop to the limits and there will be additional wear and tear of sorts?

After 2 years of overclocking, had to change the fan assembly and power brick for my G55. Luckily it was just before the warranty ended :)

anyone playing witcher 3 with oc? what kind of fps/performance are you getting? :)

I just now started OCing my 660m, since I finally got around to repasting my G55VW and my temps are WAY better. Using a custom bios, I've been able to OC my card to 1300 MHz core clock and 3000 MHz memory clock (1500 MHz actual, 6000 MHz effective). I have not altered voltage.

Is this a safe OC? It seems like at least a few others have used similar clocks for a long time - has this done any damage to your gpu? In particular im concerned about the memory overclock, since ive seen some various reports that overclocking gpu memory can fry it :/ (though ive seen other reports claiming the opposite as well)



PS i wanted to thank dreamonic and http://voltground.com/ for the custom bios....if you're thinking about a custom bios to allow for more overclocking I used voltground and it went perfectly.
