Part I

Today we are looking at some new laptop memory by Kingston that takes advantage of some late-specs for Sandybridge chipsets: 1600 and 1866 memory support. These modules are Plug N Play for i7 Gen 2 systems, tho they should be backwards compatible for earlier systems. For systems using integrated Intel graphic solutions, the gaming perks are quite noticeable. Since the GPU uses system RAM for video, the added speed can generate up to 80% in FPS increases. YMMV.

But we are interested if this DDR3-1866 stuff is good for systems with dedicated graphic solutions. So to start off, I ripped open a G73SW-A1 and swapped out the DDR3-1333 stuff and upgraded the system to 16GB. (With this much ram, you can kill the pagefile unless you are doing some really intensive video or CAD, or unless you already upgraded to a SSD.)

Just on raw thruput, the system gets a nice performance boost:

and Windows Index tops off:

And for 3DMark results: (1333/1866)

I would have to say the big surprise was the 3DMark11 scores... seems the tests benefit from transfer speeds :)

Part II will have some real world FPS tests, and Part III will involve testing the older JH/JW series.

Sweet, wanna see the FPS increase.

PART II

My overall conclusions for real world application tests show no significant increases in FPS. However, overall system response has improved very nicely, plus if you play a game that tends to have microstutters on transitions and such, then you'll see that they tend to be non-existant, and you'll have a more fluid experience in gameplay.

Video encoding tests show no improvement in FPS speeds, demonstrating that my XT drives are the bottleneck. :)

Starcraft II performance demonstrates this fluid increase very well on some maps. Mafia II's benchmark did not go up (31 fps still) but less stutters during playback. Dragon Age II still fluctuates between 38 - 60 FPS on DX11.

CONCLUSION: With a dedicated GPU and VRAM, the faster RAM will help provide a more fluid gameplay experience, possibly solving a microstutter or hesitation issues for some games. I didn't notice any better min or max FPS counts.

So, would I buy this? If I was going to do a memory upgrade to replace my 2GB sticks on a Sandybridge, then sure if the prices are decent compared to other 4GB module kits. Otherwise, I wouldn't bother for the $147 cost for 8GB just for the sake of. However there are always those who feel the need to drive Cadillac. :)

Part III

Well, this part was more of a disappointment, :(

I opened up the G73JH and swapped out the memory for 8GB of the HyperX ram. After figuring out how to get it all to boot with Dual mode, I got it running... and the system sets the RAM to 1333 mode. And it didn't help much with overclocking. In fact it was a little less stable than my Kingston 1333 RAM modules.

While Kingston says these modules are "backwards compatible" the Gen 1 chipsets only support memory up to 1333, so the JH sets the 1866 RAM to it's highest known compatible setting: 1333. I was hoping the memory would remove the limit in OC by being able to work at higher speeds, but it seems the memory wasn't my limiting factor.

So if you were thinking of 1866 speeds in a Gen 1, I'm sorry to say you'll need to upgrade to SandyBridge. :)

Man, I have a JH and now im very disappoint :( Is it possible to upgrade to sandybridge with a JH? If so, how?

Chastity@ASUS
06-08-2011, 03:48 PM
Yes, you can upgrade by buying a new laptop. It's a whole new chipset, cpu, motherboard, and matching video card. ;)

what cpu did you have when you did this upgrade? i have a i7-2630qm and wanted to see if it would work with my set up. Has everything been running smoothly with this ram upgrade, no system crashes?

Chastity@ASUS
06-28-2011, 08:42 PM
It's a stock G73SW-A1, so yes, it also has the 2630QM. No system issues at all. Also, I've done some additional GPU tweaking since, and got 3DMark 11 up to P2499 and Vantage to P10392.

Doesn't say anything about the G73JW models, do they work on them?

Chastity@ASUS
08-07-2011, 03:08 AM
Yes, but they will only run at 1333 speed. JH and JW have the same chipset, so it's not worth it.

I ordered this ram from newegg the other day and am excited on installing it. I only have one concern. Am I going to have to do a full tear-down to replace all the original ram? I am almost certain the ram my g53 shipped with is bad and I want to be rid of all of it. If I leave the once stick of 4 gig ram (the one under the keyboard and like 2 layers of other stuff) will my new kingston ram be held back because of that stock ram? When you tested this stuff out did you do a full tear-down and replace all the stock ram?

Will this new ram work in the g74 to ?

I read that it would not work unless you had a 2720qm or faster.

Chastity@ASUS
08-16-2011, 03:10 AM
Works on any Sandybridge Mobility system. However, you'll be limited to 8GB iirc on i5 systems. The 6230QM can handle up to 32GB, but W7 Home Premium is limited to 16GB.

Hey guys..

I just bought 16gb of kingston hyperx 1866mhz memory for my g74sx-xr1. Installed it, system properties shows the 16gb, but for some reason its still running at 1333mhz. Ran WEI and its still at 7.6 , read that it was suppose to go up to 7.9 . Installed CPU-Z and the DRAM frequency is shown at 665.3mhz (which is 1333mhz), but the max bandwidth of the memory at 889mhz (which would be about right for 1866mhz). At this point i'm not sure what else I can do, even tired switching memory slots for each dimm.

Any of you guys installed this ram in your g74? Please help

Your CPU supports memory speeds up to 1333 which is why it is running at that speed.

08-31-2011, 06:41 PM
thanks for the reply guys..

for now I got the 8gb kingston hyperx 1866mhz working just fine without and problems or crashes. So I would say that the 2630qm is compatible withe kingston pnp memory. However I have a problem with running 4X4gb, for some reason when I'm running the full 16gb the memory stays at 1333mhz.

I was referring to the RAM score.

All of the modules have identical timing and hw id.

Then you have 2 sets that do not work well together. Maybe you should contact Kingston, and see if they have any suggestions, or perhaps replace the ones you have with ones from the same batch.

I have a g74sx with 4x4GB Kingston PNP 1866 ram as well and have problems getting all 4 sticks to run at the right speed. I have tested each stick individually and even tested two sticks at a time with great success. None of the ram is bad. It just won't run at the right speed when all 4 sticks are in the system.

I called ASUS tech support only to be told that the max supported mem speed was 1333 and that there isnt any way to get 1866 with all 4 sticks in.

Here is to hoping this is a bios issue that will be fixed in the near future.

hi to all

question regarding this memory speed ddr3 1600mhz. This type of memory is non pnp according to one user. It needs Intel XMP thru BIOS. So if i get this type of memory , will it clock to its default speed of 1600mhz? Or will there be a bios release to put that XMP features in BIOS?

Here is the link.

There is no guarantee of success if the memory is not PnP. I don't have any of those on-hand to test, sorry.

16 Gb of this stuff would be a smashing upgrade to do and one I am planning very soon on my G74SX-CST1 (currently with 8Gb of 1333 MHz in it).
However, while Chastity and Brian@ASUS both got all 16 gigs going at full speed with G73 systems, this thread shows folks having trouble getting above 1333 MHz with the G74s.

ASUS tech support suggested to wanfeilwong that the max memory speed supported is 1333 MHz for his G74? Is this true? I can't imagine there is that much difference from the G73s used in the tests, as they all have the same processor (i7 2630QM).

If not, what could the issue be? Is it a possible BIOS issue with the newest JEDEC standards? Or are the above folks just using unmatched kits that are not playing well together?

I'd sure love some assurance that these HyperX PnP kits *should* in principal work in the G74 before I go ahead and try them...

Same here. I was planning on this upgrade, too. But now I'm doubtful. I don't see any posts where Chastity says she's seen 4 of these working in a G74. :(

hi... i was reading this forum and its very interesting. My laptop is a G73-SW 3DE, intel i7 2720QM (fsb: 1066, 1333, 1600), and ram: 16 Gb (4x4) Kingston Hyper X 1600 Mhz (blue). I run CPU-z and the memory is running at 1333 mhz. Why????????? How can i do to run this at 1600 mhz to power up my games???

Definitely interested in knowing if 16 gigs will work on the 2630 in the Best Buy models. I picked one up cheap, and am starting the upgrade train on it and it hasn't even showed up yet. I will put the 8 gig in for now, but will/how do you get all 16 to run at the same time at full speed?

i read somewhere else this: kingston hyperx 1866mhz ran stable on my g74sx 2630qm. However I did have problems running 16gb, for some reason It only ran as 1333mhz, cant figure it out. So for now I'm running 8gb (2x4gb) 1866mhz and its running fine. (http://forum.notebookreview.com/asus-gaming-notebook-forum/606929-kingston-hyperx-1866mhz-g74-2.html)

IMHO: you have to choose: (4x4) 16gb ram @ 1333 (like in my case) OR
(2x4) 8gb ram @ 1866mhz

i think the system does not support 1866mhz in the 4 slots..

(p.s. my cpu is the 2670)

Hi all.

I recive the G74sx-BBK8. For my surprice, it has the I7 2670QM with these intel turbo that send the I7 pass the 3.0 ghz. That was a small surprice. The 560gtx is 2gb. I find out the issue of the bits. sad.

I want to know is the 1333 or 1600 for the ram. I have a friend in the US until next week.

The laptop is exelent, BF3 looks good and NW3 is on the way.

If these memorys work, there will be some improvement?

Getting these sticks will probably produce no noticeable improvement over 1333 Mhz. Read the following article:
http://www.anandtech.com/show/4503/sandy-bridge-memory-scaling-choosing-the-best-ddr3

In summary, the sweet spot for Sandy Bridge seems to be 1600MHz, which produces a minor improvement over 1333 MHz. You probably have 1333MHz sticks in your G74SX-BBK8, and 16Gb of the 1600 MHz Kingston PnP will run you close to $200. But, theres no guarantee all 16GB will run at 1600 MHz in the G74: it seems no-one here can get all four 1866 MHz sticks of the Kingston PnP going any faster than 1333.

Advice: Spend less $ and upgrade your G74 to 16GB of 1333 MHz RAM. Save the extra $ for a new CPU to drop into your G74 down the road: the i7 2860QM is just out and is faster than the 2670. You'll get much more of a noticeable performance jump with a cpu upgrade. Only trouble is that its a harder upgrade to do: it requires some disassembly.

Hi fostert

That is correct. The computer comes with samsung 10666 rams.

The disassembly is easy, takes time. Beside is $600 investment there.

So it is 1333 mhz. is the best way to go?

On 1333 with work on dual channel?

What is the correct one to get, the hyper X or another one?

fostert
11-15-2011, 03:56 AM
I just got my two new Samsung 4GB 1333MHz sticks that identically match the two that came in my G74SX-CST1. With all four installed the system recognized 16Gb first boot and runs both pair in dual-channel mode at 1333 MHz. It cut my compile time for my data processing software package from about 3 hours down to 16 minutes! I was swapping an awful lot before.

https://www.superbiiz.com/detail.php?name=D3-13S4GS&title=Samsung-DDR3-1333-SODIMM-4GB-Notebook-Memory
Don't bother with the HyperX stuff. These Samsung sticks above are reliable as hell and work perfectly well together. They're cheap and the fella shipped them very fast.

Very happy!

So what is the best for these. 1333mhz.... any brand to take a good run? I read that these is the best ones. or there is another ones.

If you're gonna spend the money on these, don't just get 3: you'll cripple one of the sticks to single channel mode. get all 4 (i.e. 16 GB). Again, the only thing you'll probably notice increase is your Windows Experience Index; otherwise it'll be a pretty flat performance upgrade.

so 8gigs of 1600 or 4 of 1333mkz


what is the best 1333 mkz rams in dual

fostert
11-16-2011, 04:39 AM
As I say I got 4x4Gb (=16Gb) of 1333 MHz RAM for my G74. These are CL9. That fills all the slots in my notebook.

If you want to take the chance on 4x4Gb sticks of the Kingston PnP 1600 MHz, you should know that if all 4 modules don't happen to run at full speed (1600), they will default back to 1333 and will still be terrific (just extra-expensive 1333 MHz RAM!).

The benefits of 16GB are you can toast the Windows pagefile, and free up several tens of gigabytes of storage on your HDD/SSD. You don't need virtual memory when running 16 GB, unless you are truly running an awful lot at once.

MrAgapiGC
11-20-2011, 01:47 PM
Hi Fostert

I receve the modules on 1600 but only order 8gigs. So far so good. It detect the dual channel on CPUZ. I read and yes, it will not work on dual channel on 16gigs. I will tray to add another set of 4 gigs, in total, for 12gigs. (since these computer i used it on my office and takes a lot of memory)

Changing the CPU is not a option, takes a lot of work just to add a faster procesor.

These chips are not design to work on 1600. But is ok. Only bump the windows score to 7.8 on the ram. That has to do something! right?

Next stop the HDD to seagate XT (but that has to wait since i read somewhere that they has a problem on the factory cause the floods

fostert
11-20-2011, 05:25 PM
I'll be interested if the three 1600 MHz modules all run together at their rated speeds. Please let me know: a performance RAM upgrade might be in my future if I can determine that the G74SX indeed can handle >=12GB of those faster sticks.

I agree about the CPU: a major upgrade that requires dis-assembly, and probably warranty voidification in the process. Certainly far down the road for me, when the newest Sandy's become cheaper and the warranty is gone anyways.

Unless you benchmark alot you'll probably not notice the extra speed of the new modules, but they might come in handy later and make the difference between a future game being barely playable and totally not!

I doubt I'll be using a SSD in the near future either, until a) they come down in price, and b) their lifespan can be counted in years rather than months.

These modules, arreive from amazon for 75.00 plus shipping cost. (around 25.00) I was thinking buying the 4 gigs and not the 8.

I will order the other modules before the end of november and run the software again.

Since I have to buy the windows 7 ultimate 64bits and the HDD (2 XT MOMENTUMS),and work it out in raid 0. That is the second upgrade.

Here is the CPUZ of the computer. Remember these is the G74SX-BBK8

Let see.

UPDATE, i run the winsat mem 3 times in a row, and I made some improvement on speed.

This may sound like a crazy idea, but has anyone tried putting just 3 1866's into a G74?

fostert
11-23-2011, 04:48 AM
Can't see that anyone would...these only come in kits of 2 modules.
I am convinced its a BIOS issue totally that prevents 4 of these from working at 1866. The Kingston Docsheet for these says they only work in machines with BIOS that supports the PnP function, and the maximum speed one will get will be determined by the BIOS. After all Chastity got these working with her G73, which isn't alot different from the G74 in terms of hardware, but from what I understand has a fully configurable and richly featured BIOS...
I guess we knew this already, but its making more sense to me now.

Anyone here own a G74 and have 4 sticks of 1600 or 1866 Kingston PnP working at full speed?

11-23-2011, 03:31 PM

I look forward to hearing if your 4 sticks of 1600 MHz Kingston PnP work together at full speed. Might be an upgrade path I take one day.

Why do you need Win7 Ultimate? Home Premium can address 16 GB of RAM.

So you're getting 2x2GB new sticks to go with your 2x4GB sticks you have already? Thats 12 GB then, not 16GB. I would max it out at 16GB if you can. It sure made a difference to the stuff I run for work, but then thats not exactly everyday stuff (I don't "game" on my G74SX: its a work computer).

The BIOS of the G74 just plain is terrible, and gimped as JR sez so that one has no control over anything: unfortunatey this includess memory timings. This is why the PnP Kingston memory is such a good idea for the G74, but the problem is it doesn't seem to work at the reated speeds with the full 16 GBs.

I was trying to make order for december 1th week with the bag and the os.

One of the nice things are game performance. Not just benchmark. Game itself are smother.

I will try buying these next week. And just for fun of it, I will buy the other set of 16. If calculation are good it will not manner is 8 or 4. It will not dual channel anyway. Or I am wrong?

The reason that I will the ultimate, is cause I also use these asus for work, and the servers will not log into home premium. So I install the w7 pro on one of partition on the 2 hd , but take a lot of space. So 1 os 2 hd will be better.

I am saving for the next step, hybrid hd. Since is to expensive the ssd.

I have heard that games apparently play smoother with the performance RAM: for my own work I have seen a <5% speed difference between my desktop's stock RAM (1066 MHz) versus that same stuff overclocked to 2000 MHz. So for my notebook, I decided not to splurge on the expensive stuff.

I believe that as long as you install the sticks in pairs (from kits) they will work well together and give a dual channel path to the northbridge (on-die for the core i7s).

Ok. So 1,3 and 2,4 are the pairs?

I think this is the way the dual channel path is enabled, yes. On my desktop (Gigabyte P55A-UD3P board) the manual indicates that DIMM slots 1,3 are to be filled first with two identical sticks to enable dual channel, then 2,4.

My model of the G74SX (CST1-CBIL, which is the Staples Canada version) came with 2x4GB=8GB installed in slots 1 & 3. I get about 14GB/s bandwidth, which is enormous and only achievable in a dual channel config. One would also assume ASUS did this right to enable dual channel mode to the memory controller on the die, but thats a weaker argument!;)

OK, here are my results;

4 1866 do NOT run at 932.1 MHz, but 2 running in dual channel DO. Although it seems unstable because it wouldn't always finish a restart. But I had the sticks in board #s 1,2 which is 1,3 in HWInfo64 and 2,4 in CPU-Z. If they were populating the second group instead of the first would that cause unstability?

I got a nice jump in 3DMark Vantage but 3dMark 11 crashed, so I'm just going to leave all 4 in and let the notebook run at 1333.3 until/if Asus decides to unchain the G74's and gives us a BIOS with a REAL setup that caters to the people that this notebook is aimed at; gamers.

There should be *no* instability whether you put the pair in 1,3 or 2,4. What do you mean it wouldn't finish a restart? Windows won't restart, and just hangs?

If you are experiencing instability with either configuration then swap out those two and put the other two in there. If you find one combination that works, the run memtest86 from a CD and test the other pair: keep testing all possible pair combos until you find the stick(s) that produce memtest errors. Corsair *always* replaces performance memory that fails memtest86 (I've RMAed failed DDR3 with them before and they just send you a new set, with a free cooler!),and so should Kingston if they're a decent company.

Its a good idea to test all four sticks in there with memtest86 too, JIC....

When i do benchmarks, I always restart then let the system settle down before the next one. When I say it wouldn't finish a restart it was getting stuck and I had to remove the battery. This only happens when I have just 2 running at 1866, when I have 4 running at 1333 all is fine. I think the BIOS doesn't like what it sees and stops the boot. After all, this setup is rated for 1333... Despite what Chastity said, I don't think the G74 will do 1866 without a new BIOS. The G73, maybe . . .

Thats sad, that is. The G74 is supposed to be an advanced or improved G73, no? Advanced hardware crippled by BIOS...

Still worth checking those sticks with memtest86+. You paid good money for those, and if you need to RMA em, might be easier now than later.

I still wonder if 4x4GB=16GB of that 1600MHz DDR3 Kingston PnP HyperX would actually be recognized? The 2nd Gen core i7 2630QM is rated to 1333, but 1600MHz isn't that much of an overclock for the SB memory controllers, which are very tough.
I would just love it if ASUS released an opened up BIOS for our machines....

I already brought up the subject to gary_key through a pm and he says he's waiting for an answer from Engineering. Perhaps if enough people bother him he'll push harder. :D

BTW, that RAM memtested ok. It's just the BIOS putting the kibash on 1866. Maybe 1600 works better but I wouldn't count on 4 working at that speed.

Well I hope they do something soon. I ordered 16GB of the Kingston, installed and found it not recognized. I'll lose my butt returning 8GB. I wanted all 16 to avoid any virtual memory on drive. If it can work in the G73 series there should be no reason not to work in the G74 series!! This is the ONLY issue I have with this laptop! I love it. SSD and a hybrid data drive all I needed to tweak it was the 16GB to operate at full speed.

Next upgrade if the RAM issue is settled is the Seagate Momentus XT 750 GB 7200RPM SATA 6Gb/s 32 MB Cache 2.5 Inch Solid State Hybrid Drive ST750LX003. The only item I am missing is the 3D 120mhz refresh screen.

You shouldn't get rid of your page file no matter how much RAM you have. In fact more RAM requires more pagefile. According to MS the pagefile should be size of RAM + 300MB.

I don't see any reason for MS to lie about this, I mean why would MS want us to use diskspace for no reason?

Haven't had a page file since I got my 16Gs. Windows has never BSODed, nor thrashed around, but granted I don't push it too hard either (Windows has a history of spinning itself out of control sometimes even with its own background processes, so I've learned never to rely on it too much for stability, even with alot of RAM).

I apologize for opening an old topic but figured I'd post my findings here.

I just received 2 sets of Corsair Vengeance (2X4GB). These are set to run at 1600MHz but my G74-SX only recognizes 1333MHz. Does anyone know if ASUS plans to release a new BIOS soon so we can take advantage of new hardware like this?

This is has been discussed a lot, and many users are hoping for such a BIOS update. But unfortunately, Asus doesn't offer any guidance on what they're developing, if anything.

I'd love to see a G74 BIOS update that addresses a few issues that come up frequently, but honestly, I'm not very hopeful. They don't have a great track record on model support, especially as they prepare to release new models. But we can keep our fingers crossed, I guess.

@bsawchuk: can you run memtest86+ please? I'd like to know what the SPD timing info is being read as by the BIOS.

What are your normal specs on those sticks? (i.e. 9-9-9-24, or ...)

I am suspicious that the BIOS is reading the timings wrong (i.e. CL6, instead of 9), and then compensating by downclocking the clock speeds on the sticks.

Sorry for the delay, I will run the test and let you know the results.

I have G73 JH with 920xm, Window7 ULTI
I want to upgrade the ram and I just want to get the facts right before buying

It does not support anything higher than 1333Mhz or 1.35v setting.
but does it support 32gb 1333Mhz ram?

Thanks

Anyone try this before? Very good price for 16Gb
