Does anyone here know if the G74 series will take the new 8GB DIMMs that are just starting to populate the market now? I.e. can one upgrade the G74 to 32GB of RAM by putting four of these in? I'm running Linux on the G74 and certainly will be able to address 32GB if I could get it...I also read that the i7 2630QM will actually address 32GB, but will only run it in single channel mode (anything that uses up to 16GB will run that first 16GB in dual channel mode).

Sorry I can't be of use in your inquiry but I was wondering what sort of tasks do users (not business oriented computation) with 32GB of RAM actually do on their laptops for instance O_o ?

if this thing will see that much, and i doubt it, the only benefit i can see is in the channeling...oops i see tc is on it

Sorry I can't be of use in your inquiry but I was wondering what sort of tasks do users (not business oriented computation) with 32GB of RAM actually do on their laptops for instance O_o ?

I am a radio astronomer by trade, and the datasets I deal with are very large (e.g. 1/2 GB for a single image, and >100 GB for one datacube). As well the software that processes it needs to have access to alot of RAM. For example, some of the fortran programs I run to process data actually take 14GB RAM to just compile them! Then, in running some of these tasks (e.g. fast fourier transforms) those programs will often use 8-12 GB RAM. As well, visualizing the data (i.e. display it) and being able to take in the big picture while simultaneously seeing fine details is the way big science is done today in radio astronomy. With 16GB of RAM I can display 16GB of data at once, which is pretty good, but twice as much would be a more efficient way of looking at it, and might make the difference between discovering something new in the universe or missing it...

Quite simply hardware has not caught up to the amount of data that is produced by today's observations.

Anyone out there that knows if the G74 can actually take 8GB sticks?

I strongly suspect the answer is no. If only because, in my experience, a BIOS includes RAM compatibility info, so when Asus product specs say the G74 supports "up to 16Gb" they mean that that's all they have accommodated in the BIOS.

I'd be very curious if anybody is willing to buy 8Gb modules and see if they're recognized. If they're not, I can't see any reason a future BIOS update couldn't fix that.

I found this site: http://www.powernotebooks.com/ASUS-Custom-Built-Gaming-Laptops-Notebooks-cat-65.html
These guys will customize the G74SX to your order, including putting 4x8GB=32 Gb into it (for an extra $1095).

I could get 4 of these for under $500:
http://ncix.com/products/?sku=64472&vpn=CMSO8GX3M1A1333C9&manufacture=Corsair

Maybe they also tweak the BIOS for you if there is a limitation there?

OK, so I have decided to gamble...have ordered 4x8GB sticks of
http://www.corsair.com/memory/notebook-memory-upgrades/value-select-8gb-ddr3-sodimm-memory-kit-cmso8gx3m1a1333c9.html
from NCIX. Everything I have read suggests that the core i7 2630QM will have no trouble addressing that much, so it comes down to the BIOS in the G74. If its hardcoded to only deal with 16GB then I will have to decide whether to keep the RAM and hope for an ASUS BIOS update to cure my problem; otherwise I have 15 days to return the 4 sticks (minus a 15% restocking fee...oh well, as I said its a gamble).

RAM has arrived today but I am too tired to put it in tonight...will probably try this on the weekend.
Watch this space for my results...

You cannot use 32GB of memory on the G74. Intel limits the memory controller to 16GB - very few laptops will currently support 32GB of memory and none with standard consumer-grade dual or quad-cores will.

I REALLY HOPE for a new bios version regarding at least the G74/73/53/52/51 models..

And the Lenovo with the 2630QM runs 32GB:
http://asia.cnet.com/product/lenovo-ideapad-w520-core-i7-2630qm-processor-2-00ghz-32gb-ram-45483516.htm

And as mentioned these guys http://www.powernotebooks.com/ASUS-C...ks-cat-65.html will outfit the G74 with 32GB (even the ones running with the 2670, which has identical specs according to ark.intel to the 2630, except 200 MHz more...).

BTW, until just a few weeks ago that same ark.intel page on the 2630 claimed that the max memory compatible with the 2630 was 8GB! Check out
http://communities.intel.com/thread/22441?start=0&tstart=0

so I'm not sure if ark.intel is trustworthy.
I think if it doesn't work it'll be a G74 BIOS issue, and not any crippling of the 2630's memory controller by Intel (I've never even heard that they do that!).

So, we'll see when I get around to this. Looking like a weekend thing.

Remember that the information released by intel is only information current at the time of release, they do not update once BIOS updates are released so only the defaults are posted.

Well I spent the AM installing and testing various configs of 4GB SODIMMs and my new 8GB SODIMMs from NCIX. The results are in...

The G74SX and core i7 2630QM **CAN** use 32GB of RAM! Attached are two screenshots (from my point-and-shoot camera) to prove it: one is a shot of my BIOS (v 203) front screen showing the amount of RAM detected by the BIOS, and the second is a shot of memtest+ testing my new sticks. Linux boots fine and happily reports all 32GB to be present and accounted for, and stupid Windows HP of course can see the 32GB but reports only 16GB usable. No matter-its a windows limitation.
Also tested the system with 2x8GB and 2x4GB in the other two slots (total 24GB): works terrific as well in the G74.

I haven't let memtest run through a single whole pass yet, but will be doing the standard 3-pass test this afternoon (testing 32GBs will take several hours) to make sure these sticks are good.

For everyone here who may be interested in the upgrade to 32GB one day, the sticks are Corsair (CMSO8GX3M1A1333C9) 1x8GB DDR3-1333 MHz 9-9-9-24 204 pin. I realize its overkill for most users, but for my purposes with this notebook (data processing and research) it moves the G74 from desktop-replacement to the realm of workstation-replacement.

I had a feeling....the $400 risk was well worth it.

4x4GB Samsung 1333 DDR3 for sale...!

That's the published limit for Windows Home Premium, so not a surprise or legitimate criticism.. Simply upgrading takes it to 192Gb.

fostert
12-20-2011, 03:15 AM
Further to my experiment: the sticks all check out fine with memtest86, and surprisingly the bandwidth (14GB/s) is the same with 32GB as it is with only 8 or 16GB of installed. There was some chatter around the intel forums that for programs that use above 16GB the 2630QM would run the RAM in single-channel mode (which should mean a drastic penalty in bandwidth), but that does not seem to be the case: my fortran compile test uses 36GB of real and virtual memory (32GB physical +4GB swap) and timing indicates the same bandwidth even when all 32 is being used.

So it looks like good news all around for 32GB and the G74SX...now if only ASUS would release a BIOS to allow performance seekers to use 16GB of the performance DDR3 out there, like the stuff corsair has just released in their vengeance line!

< blush > kind acknowledgements! Yeah, I can imagine why ASUS would underrate their notebooks, to discourage owners from future upgrades of their old hardware and encourage them to upgrade to totally new hardware! Especially those that buy the best to begin with...companies assume then that you'll always want the best and be willing to abandon your old systems completely.


i wish i would have seen this before coming back to fiji.

Actually I wish I hadn't done this for a few more days...I paid $120 per stick to NCIX, now less than a week later the cursed things are down to $90 each. Blast.:mad:

I'm guessing I haven't made this clear...see attached screenshot of my G74 under Debian Linux with 32 of a 64GB datafile loaded, and look closely at the xterm. All 32GB is used by the display program "kvis", and some swap to boot.

In Windows sure enough the operating system will only use 16 of the 32GB it sees, but thats because its Windows 7 HP. I don't own a license key for ultimate.

In short, ASUS underrates the G74's max memory supported specs.

I wonder if they do know and are just purposely underrating them to get everyone to want to upgrade to the "G75" or whatever they have got coming next. Or yeah, it could be that they don't know that 32GB would work, since it is an uncommonly large amount of RAM that virtually no-one would ever fill ('cept lil ol' me).

Awesome, Microsoft gave me a serial number to upgrade to Pro for free, after spending literally 8 hours on the telephone with their support department helping them to try to figure out what went wrong with my old desktop computer and the Windows update system.

Now, I just have to wait until it comes on sale somewhere and makes 32GB affordable, I saw some 8GB sticks at $75 ea., but didn't really feel like spending $300.00 at the moment to upgrade to 32GB, especially so soon after spending the cash to buy this laptop.

Anyway thanks, there has to be a first person in situations like these. Much appreciated.

At NCIX those Corsair 8GB sticks (1333MHz, 9-9-9-24) have dropped in price by 35% in the past few weeks (!!), so I'm sure they are on their way down even further in the next few. Wise to wait if you don't need them right away. Eventually though I'm sure 32GB will be dirt cheap and beckon loudly at many G74 owner's doorsteps!

Ah, I see.
Speaking of ASUS only speccing the G74 with 16GB max, I wonder why they are **still** sticking with this same max spec in the new G75? That thing can supposedly only support a max of 16GB @ 1600MHz, but I'm fairly sure the Ivy Bridge IMCs will easily do 32 GB or even 64 GB. Do they not follow what the users on this forum are doing with their G74s? Besides, by mid-to-late 2012 16GB SODIMMs will be hitting the market (DIMMs are already available now, and I have seen one 16GB SODIMM stick for laptops offered by samsung...for $4000!).

Do you know Asus G73SW and G74 supports 32GB of ram so you dont have to worry about that. It will work for sure. and it supports memory speeds up to 1600MHz . your upgrade will be worth. But for g73jh/jw users, they have to stick with 16gb.

fostert
02-02-2012, 03:49 AM
Read around here my friend...I have been using 32GB in my G74 for two months now.
Also, the G74's BIOS does not support 16GB of RAM at 1600MHz or higher. Nobody here has gotten more than 8GB at these clocks to work in their G74 to my knowledge. We're all waiting (perhaps futilely) for a BIOS update from ASUS to fix this.

Is that for a pair of 8GB sticks I hope?? Thats steep for just one. NCIX Canada has few 8GB sticks for a really good price ($75.87 Cdn each), but they seem to be temporarily out of the 2x8GB=16GB kits ($147.34).

Good to see another Linux user on here! I myself came from a fedora/redhat based distro (Scientific Linux), and am now using Debian, a "hackers" distro. I actually don't mind it.

Well folks around here have gotten 4x4GB=16GB of the 1600 MHz Kingston PnP Hyper-X to run, and
from what I've read people here have had better luck with the corsair vengeance modules Auto-SPD (i.e. the Auto-overclocking feature with registers containing XMP profiles that are automatically read in to the BIOS at boot) than with the Kingston Plug-n-Play Hyper-X modules (where no one could get more than 8GB of the 1866MHz stuff working at their rated OC speeds). At that crazy low price there on newegg you can't really go wrong, especially if you get the 2x8=16GB kit, which would be two modules matched by corsair themselves and guaranteed to work well together esp. at 1600. If 32GB worth don't work at 1600 the lot will surely work at 1333, and that stuff is only $10 cheaper per module. If it were me I'd take the $40 risk, and if they don't run at 1600 then read this...
http://www.anandtech.com/show/4503/sandy-bridge-memory-scaling-choosing-the-best-ddr3

which shows that 1600 really isn't all that faster than 1333 in real world use anyways!

But I guess the real question is: do you absolutely need 32GB?

I have read the user manual for the G55 on ASUS ftp site: ftp.asus.com.tw/pub

It appears that the G55 at least will only have two RAM slots:mad:, which means that with the presently available SO-DIMMS (8 GB), the maximum memory is ging to be 16 GB. If this is true, ASUS, please change it. Some of us would like to have quad-slot memory configurations. That was one of the benefits of the G53SX (16GB for $50 upgrade).

If this is true, ASUS, please change it. Some of us would like to have quad-slot memory configurations. That was one of the benefits of the G53SX (16GB for $50 upgrade).

The conventional wisdom is that the number of RAM slots on a notebook is also a function of the CPU it is designed to run. The memory controllers are now integrated onto the CPU die rather than being in a separate northbridge chipset. When it comes to mobile CPUs Quad Core chips can address two separate pairs of DIMMs, whereas dual core chips can only address one pair of DIMMs. If the laptop is designed for a dual core CPU in it, there is probably no reason for the manufacturer to go to the trouble of putting 4 slots on the board, even if the CPU could be upgraded by the user to a quad core.

Not to worry; if you want 32GB the wait won't be long for 16GB SODIMMs. 1x16GB DDR3 DIMM sticks for desktops are already populating the market.

Zygomorphic
03-25-2012, 08:40 PM
I own a G53SX, so I am not in the market for another computer. The big issue with the quad-slot is it makes memory upgrades a lot cheaper. Remember when 8 GB was crazy big, the G73JH could reach that with 4x2 GB config. Now, we are looking at 32GB in the same way...

However, I thought that others might be interested in the link to the manual for the G75:ftp://ftp.asus.com.tw/pub/ASUS/nb/G75VW/E7093_eManual_G75VW_Z103.pdf

On pages #63-68 of the manual above, the schematics are unclear as to whether the G75 will have quad-slot memory. Based upon the diagram, I am guessing that it will.

From the bits and pieces that I can glean from the internet at large, it appears that the next-gen ROG laptops should be outfitted with quad-cores. At present, ASUS is doing so, and I don't see them changing this. However, the quad-slot config is still a dual-channel. The Core i7-2630QM is a dual-channel processor, as are all of the mobile Intel quad cores that I know of. However, it is still possible for the mobo manufacturer to outfit the notebook with more memory slots than there are channels on the controller.

Even the new X79 desktop chipset which now supports true quad-channel memory has more than four slots. It is pretty common on desktops, but quite rare on notebooks: a few ASUS machines, an Acer, Alienware, and a few other boutique vendors. I have to wonder why more don't, as it is a cheap way of making a laptop run a lot better (or at least brag that it does). I considered the quad-slot memory on the G53SX as one of the deal-breakers when I bought my laptop. I run multiple VM's, so being able to allocate 4+ GB to a VM is a huge plus.

I also have a similar concern with regards to my ASUS G74SX-BBK9.

I would like to upgrade my laptop's RAM from 8GB to 16GB in the near future, however I currently have DDR3-1333 installed in it and was kinda wondering if my laptop can support 16GB DDR3-1600. I researched about my processor's supported range (Intel Core i7-2670) and it said that it can support 16GB DDR3-1066/1333 only, but after reading the replies in this post, I got confused on how things work. I'm not that much of a hardware nerd/geek and I'm having a hard time understanding many things so far.

I would really appreciate it if someone can help me with my concern and I deeply apologize if ever the answer to my concern has been answered already in the previous replies. Thank you very much!

You MAY be able to run 2x8GB @ 1600, but I don't know. There may be some other posts on here about that. Running 4x4GB @ 1600 is not possible, though. The speed will be clocked back to 1333 if you do that.

You're correct...8Gb will run at 1600, but 16Gb runs at 1333, regardless of the RAM's rated speed.

Thank you very much for your replies and help! So in that case, it's not recommended for me to buy 16GB DDR3-1600 for my laptop but instead I should choose 16GB DDR3-1333 for it right? Thanks for clarifying that to me.

I just have another question with regards to DDR3-1333. I kinda noticed on Newegg that there are DDR3-1333 (PC3 10600), DDR3-1333 (PC3 10660) and DDR3-1333 (PC3 10666), is there somehow a big significance if I buy the DDR3-1333 (PC3 10666) when it comes to performance and will it possibly be compatible to my laptop or should I just stick with the DDR3-1333 (PC3 10600) instead?

Again, thank you very much for all your answers and help guys!

Thank you very much for your replies and help! So in that case, it's not recommended for me to buy 16GB DDR3-1600 for my laptop but instead I should choose 16GB DDR3-1333 for it right? Thanks for clarifying that to me.

I just have another question with regards to DDR3-1333. I kinda noticed on Newegg that there are DDR3-1333 (PC3 10600), DDR3-1333 (PC3 10660) and DDR3-1333 (PC3 10666), is there somehow a big significance if I buy the DDR3-1333 (PC3 10666) when it comes to performance and will it possibly be compatible to my laptop or should I just stick with the DDR3-1333 (PC3 10600) instead?

Again, thank you very much for all your answers and help guys!

For safety's sake, I would stick with the PC3-10600. I have 16 GB of the stuff running at 1333 MHz in my G53SX without problems. A better idea would be to run memtest86+ and determine exactly what you have. If you have the higher speed stuff, get more of it. My guess though, would be the PC3-10600. Newegg in one of their yolk'd episodes talked about it, and Paul said that it was more of a marketing gimmick than anything else.

Thank you very much Zygomorphic for you kind response! In that case I shall do that and buy 4x4GB DDR3-1333 (PC3 10600) for my G74SX-BBK9. I just have a curious question, aren't there any DDR3-1333 (PC3 10600) that have heat spreaders on them?

hey fostert im triying to get my 16gb samsung 4x4gb at 1600 mhz to run on my g74sx any idea what do i have to do ? Sorry...been crazy @ work lately.
I'm fairly sure that I've read about someone here who got 16GB running at 1600 in the G74. It is likely someone who was using either the Kingston PnP stuff or the Corsair vengeance notebook stuff. Both include XMP (xtreme memory profile) settings programmed in to them to auto-overclock the on-die integrated memory controller and bus to 2x800MHz = 1600MHz. Having sticks pre-programmed with SPD settings for OC speeds is the only way you'll get >1333MHz from RAM, since the G74 BIOS does not allow any manual tweaking or manual OC settings in it. I'm not certain, but I don't think the samsungs have an Overclocked SPD setting programmed into them like the corsairs or the kingstons do, so they'll be stuck at 1333MHz. Even if they are rated at 1600MHz, they won't run at 1600MHz unless the BIOS tells them to, and thats what you need the SPD settings to do.

Heatspreaders are a complete gimmick to give the illusion of high performance. Even the corsair 2000MHz GT desktop RAM I run in my desktops (which has wild red heatsink fins and spreaders) are barely warm to the touch, even at 2200MHz! Todays RAM runs at very low voltages (1.5-1.65V) and you are never going to get them hot enough from overclocking to need to cool them. Never. The only time you need cooling is to lower the internal resistance enough (electrical resistance scales with temperature) to get that last hertz or two of clock tick above the transistor's activation point, which is only going to happen when you are pushing them to their absolute limits, a scenario you'll rarely achieve in a desktop, and never ever in a notebook.
Forget about the flashy heatspreaders. Useless.

Thanks for your reply to my post fostert! I shall forget anything about heat spreaders in that case.

Anyway, with regards to your post, so you mean that Kingston PnP DDR3-1600 (PC3 12800) or Corsair Vengeance DDR3-1600 (PC3 12800) memory modules will still run at 1600MHz even if the BIOS of G74 models don't support more than DDR3-1333 (PC3 10600)?

I'm very sorry for asking too much questions, I'm just learning more on hardware configurations and stuff related to it. Thank you very much again!

Yes they will, because the BIOS will read them first and try to run the bus and IMC at whatever speed they say they want to run at. A BIOS is just a set of instructions to read settings from various bits of hardware, and get its parts to communicate with itself and with software that is loaded after POST.
Normally it looks for default JEDEC standard SPD settings programmed in the RAM and runs the IMC and bus with those default clock speeds and timings (e.g. 9-9-9-24 @665 MHz, double data rate = effectively 1333 MHz speeds). In BIOSes that can be manually tweaked you can manually direct the BIOS to instead read other settings in the RAM. Performance RAM usually has at least one INtel XMP setting in it to overclock the IMC and bus, and overclockers use these settings (or even go beyond them). But in notebooks like the G74 we can't manually do just about anything at all in the BIOS, so the market has grown to include Kingston PnP and Corsair vengeance notebook memory which have Intel XMP settings as default, to trick the BIOS into reading the overclocked settings first. The BIOS then checks with the IMC on-die to see if it wants to run that fast. The IMCs of 2nd gen core CPUs are tough lil buggers and also are built by Intel for some mild overclocking, so they are usually fine with the settings like 1600 or even 1866, and theoretically thats how the notebook can get its whole memory subsystem to run at these clocks. ASUS may have programmed it BIOS specifically to reject some fast XMP settings (e.g. 1866MHz) from all 4 banks of RAM, since that places a greater electrical load on the IMC and therefore may stress the notebook's CPU cooling solution (just my guess).

I am 98% sure that I have read on here from some people that have had success with 4x4GB of the corsair vengeance 1600 MHz memory (http://www.corsair.com/memory/notebook-memory-upgrades/vengeance-4gb-high-performance-sodimm-memory-upgrade-kit-cmsx4gx3m1a1600c9.html) in the G74: I even remember asking the guy if it was 2x8GB or actually 4x4GB, and I'm pretty sure he said 4x4GB. I'll look around for that post. the Kingston Plug-n-Play HyperX stuff seems to be more problematic; AFAIK no one has gotten 16Gb of that stuff running at 1866 MHz (only 2x4GB=8 GB worked at those clocks), and I'm not sure I remember anyone trying the 1600 flavour of Kingstons.

forstert do you think that asus would release a bios to fix the g74sx num lock/ ram speed problem ? because i got a great deal on this samsung 16gb at 80$ i was going to return 8gb back but im not sure i should .

Keep the RAM. If it works (I assume you have a G74), great. If not, you can decide whether or not to return it. If that Samsung RAM you have is all matched, I would say definitely keep it. The benefits of matched RAM are that they are more likely to work well together, especially dual-channel, which if poorly matched will run in single-channel mode.

Fostert, +1 for excellent work. ROG'ers, I think we have a pro around here... :D

Thank you very very much for your very detailed explanation! I'm not sure how pointing system works since I'm just starting to posts in forums, but I'll copy what Zygomorphic did.

+1 for Fostert! I hope someday I'll be able to atleast be near your knowledge of expertise when it comes to hardware stuff and be of help to others also. Again, thank you very very much!

What do you mean by pointing system? If you are talking about reputation, click on the little star on the bottom-left corner of the post. It will then ask you to leave a comment about the user's reputation. Then click "OK".

Also, what are you copying? Is it keeping the RAM? I happen to own a G53SX, which is an order of magnitude more difficult to upgrade. The G74 is easy, as the G55 looks like it will be. I had 8 GB originally in my computer, and then bought 8 GB more of DDR3-10600 RAM to expand it to 16 GB. At the same time, I put in a Seagate Momentus 500GB 7200 RPM Hybrid drive. The extra memory has been useful, but the Hybrid drive has about half paid for itself in time saved on boot--literally!
5400 RPM boot: 1.3-1.5 minutes.
Hybrid Boot: 0.5-0.75 minutes

LINUX boot is even faster.

I'm just new to forums and stuff so I'm not knowledgeable about these things. I wasn't referring to copying any hardware configuration or anything related to it, but was just referring to the "+1 for Fostert", I'm sorry for the misunderstandings. I will try and check out the reputation system later on.

With regards to using Hybrid Drives, that's kinda out of my league as of now, whether it be knowledge about it or money-wise. I would just try to cover that area at the right time and at the right budget, but thanks for giving me such awareness to the advantages of it Zygomorphic!

Again, sorry if I caused any misunderstandings during my previous post.

Just to confirm what others have said, I have also decided to upgrade to more then 16GB Ram and it works fine as long as your OS Supports it (W7 Home Premium will not show over 16GB). I ended up grabbing some Corsair Vengeance and plan to upgrade all 4 slots. Currently running 24GB (8x2, 4x2). 1600Mhz DDR3 works fine, just downclocks to 1333 which is fine.

Ram I bought is here:

I was under the impression that with the corsair vengeance you could run @ 1600 mhz because those cards don't require bios configuration to run at those speeds ?

I cant run at that speed currently most likely due to also running 2 of the original sticks which are only 1333. But I also remember someone stating that you can run 1600Mhz only if you use 2 DIMM slots? I think that was said by someone on here where if all 4 slots are filled, you can only run 1333.

I also have the Corsair in slots 1-2 so it should read those 1st and run @ 1600 if possible. I just dont think its possible with all 4 slots filled. Please feel free to correct me if Im wrong.

04-02-2012, 06:33 PM
Wow. Well, I can say that with just 2, they do run @ 1600. I took out my 2 stock 4GB's in there and with just the Corsair, it does run @ 1600. Nice to know. I'll also be picking up a second pair, but not sure how soon.

Just have to make sure you stagger the sticks (if only running 2). In channel 1/2 the Ram was single channel and running @ 1333. Had to move to channel 1/3 to get dual and 1600. Not sure of the performance improvements, tempted to leave just the Corsair in here for the 1600, heh.

maybe yours is different but my g74sx-bbk8 can run @ 1600mhz dual channel in slots 1and 2 , i was using a pair of samsung with no problem last week before i return them for the corsair.........

Sorry to hear they don't run at 1600 MHz. I was fairly sure another on this forum had gotten 4x4GB of the Corsairs to work at full speed. Certainly it looks like 2x8GB=16GB will run at the 1600 speeds...

Lets try the following:

1) What verions is your BIOS?
2) Download and burn onto a bootable CD memtest86+ 4.20 (http://www.memtest.org/download/4.20/memtest86+-4.20.iso.gz). Boot and run. What clock speed (in MHz) and CAS latency timings (e.g. 10-10-10-27, or 9-9-9-24, etc...) are reported when all four of your sticks are installed? Does shifting them around in the four slots make any diff to the speed?
3) What clock speed (in MHz) and CAS latency timings (e.g. 10-10-10-27, or 9-9-9-24, etc...) are reported when only two of your sticks are installed? This info will be interesting...I have suspected for a while now the BIOS incorrectly reads four PnP sticks' timings as something insanely tight (6-6-6-18 for example), which will never ever work with the memory controller at 1600 MHz speeds (too much of an overclock).
I'd like to find out if this is the case with your sticks.
4) Run the entire memtest for 3 passes minimum. If *any* errors (even just one) are reported, you have a solid RMA case for Corsair. They are superb at replacing memory, and will even help troubleshoot your problems further.
5) Check with Corsair about what kind of guarantee they have when their products do not run at their own rated speeds.

well i have done memtest already individually 2 times per pass and i get no errors it takes for ever.

this is what i get with just two mem,

Ram frequency - 798.5

Dram - 1:6

latency - 9.0

Delay - 9

Precharge - 9

Cycle time - 24

and this is what i get with all of them installed

Ram frequency - 665.3

Dram - 1:5

latency - 9.0

Delay - 8

Precharge - 8

Cycle time - 20

no moving them around it doesn't help i even upgraded to windows 7 pro and nothing ......

and last i will b calling corsair soon and ask for input in this.

no luck with the corsair vengeance , i called them up and explain to them that the memory were not auto overclocking and the guy new right away what i was talking about ( i guess other g74 owners have call before ) he told me that it was the memory controller that was not up to date , even if we did not had bios open to overclocked with an up to date memory controller they would auto overclocked , we mem tested and everything was good he did gave me the option to get my cash back but i'm keeping them hoping for a bios update......

I just couldn't help myself. I Decided to order 32gigs (4x8gigs @ 1600mhz) dimms. I'll let you guys know how these perform when I get installed and tested. If it works, awesome. Either cases I'll let you know. 16 gigs @ 1600mhz isn't a big upgrade from the previous configuration with 12 gigs @ 1333mhz I gotta agree. With 32 gigs @ 1600 mhz that will certainly make a difference on operating large images and some other stuff I'm working on and other stuff that I still have to figure out. So far I'm in for the 32gigs @ 1600mhz Corsair Vengeance challenge :p

I don't know what programs you run that use that much RAM, but hey, more power to ya! But just a couple reminders:

Only Windows Pro, Ultimate, or Enterprise will use more than 16Gb of RAM, so if you currently have Home Premium, don't be alarmed if you install the RAM and it only reports 16Gb. Just do the Windows Anytime Upgrade if you need to upgrade your Windows edition....it's the quickest, easiest way.

Also, the RAM will run at 1333MHz, not 1600Mhz. That's built into the G74 BIOS, but so long as the RAM is good (and Corsair generally is), it should be stable at 1333MHz.

OmegaMan

Yup, I knew about that windows HP issue, upgraded last evening for ultimate, the price difference between Pro and Ultimate was 20$, so like the usual "why not?" poped up, I decided to go for it. I had a little problem as win 7 HP wouldn't upgrade to ultimate with the full install DVD... go figure. Even the guy at MS tech service told me to do a clean install. Untill I decided to reboot and it upgraded from HP to Ultimate in less than 10 minutes.

As for the dimms I bought they claim that these are plug and play and they should clock their way up to 1600mhz. We'll see on Tuesday when I get my stuff delivered, installed and tested. I think that I've read somewhere on this thread that someone upgraded his laptop with 2x8gigs of the same ram, and that the dimms clocked @1600mhz, but because of his other old ram he was downclocked @1333mhz.

I can remember back in the days when we were running windows stuff with 8MB of ram and that other guy that was working with 32MB of ram he kinda like payed 1200$ to get that much ram in his PC back then. Crazy to see the evolution over 15 years or so. With 32 gigs I will mainly use high end 64bits graph and cad applications, and I know that it'll just be faster to accomplish my work with that much ram in there. I'm just stuck with that old mentality that a lot of ram is never enough. I'll see. :D I almost forgot, what application would you suggest to test these ? Thanks.

Corsair is good to deal with in case they don't clock up to 1600 (which seems likely since you're putting in 4 SODIMMs); theres lots of tremendous help on their forums (asktheramguy.com) and they most likely will offer you an exchange or refund if they can't get 'em working to your satisfaction and the rated spec level.



I can remember back in the days when we were running windows stuff with 8MB of ram and that other guy that was working with 32MB of ram he kinda like payed 1200$ to get that much ram in his PC back then. Crazy to see the evolution over 15 years or so. With 32 gigs I will mainly use high end 64bits graph and cad applications, and I know that it'll just be faster to accomplish my work with that much ram in there. I'm just stuck with that old mentality that a lot of ram is never enough. I'll see. :D I almost forgot, what application would you suggest to test these ? Thanks.

Yeah, I remember when RAM for my 386 was up to $100 per MB! There was some fire in a RAM factory in Asia somewhere in 1993 and the price of RAM skyrocketed then. The 386 came with 1MB and Windows 3.1 thrashed and hashed on boot and with every click, but then I upgraded to 4MB and wow: what a speed increase!

Test the hell out of those new sticks of yours with memtest86+ (4.20). Download an ISO (http://www.memtest.org/download/4.20/memtest86+-4.20.iso.gz), burn the image onto a CD and boot off it: let the testing run for 3 complete passes. If any errors are found (even just one) Corsair will replace them. They are that good!

That's good to know, so far I've been browsing around and have gt new stuff that I didn't knew about SSD's.

All good, I wanted to make sure that memtest was kind of the most reliable free option out there. So far the sticks are still in New Jersey, so like I know the customs to retain stuff just for the sake of it, I do not expect these to get around my spot before next Friday, sucks :mad: I hope they'll be around before they get the 2000mhz 16 gigs pnp sticks out :p

Thanks for the help Fostert.

Hello.


I have a factory 8GB memory on my machine, I bought two 4 GB sticks, when I installed them the laptop does not start, so I took one stick out with 3 of the 4GB sticks and the machine starts, the laptop is upgradable to 16GB, so what am I doing wrong?

I have a quad-core 2.0GHz Intel Core i7 2630QM CPU up to 2.3GHz , an Nvidia GeForce GTX 560M GPU, a 1TB hard drive, a B of RAM., its upgradable to 16GB but why am I getting no start.

if anyone can shead light on this I'd be greatful.



Thanks.

Welcome to Forums, asus3208.

Are the two 4 GB sticks you just bought, the same brand/model with the other two stock
4 GB sticks in your laptop? Different brands of RAM sticks mixed together (even if they have
the same configurations), could be quirky. But sometimes, they could work well together.
(I currently have 3 x 4 GB ASint and 1x 4 GB Kingston.)

The ideal for RAM should be that they're all of the same brand/model.

Another thing is that perhaps one or more of the RAM sticks is/are faulty.
So, I suggest you read over fostert's #73 post once more and use that
Memtest86+ to test your RAM modules.

+1 to Pilgrim...

You'll want to focus on the two sticks you just bought, so boot the memtest86+ CD with 3 of your four sticks installed, and let memtest run for 3 passes (probably take an hour or two...). If no errors then do the same with the other new module installed in the same slot. If no errors still, then test with the third RAM stick installed in the opposite slots. This will help you identify the faulty stick, if any.

If at any time memtest86+ reveals an error, you have a case for an RMA with your memory manufacturer. All good companies will gladly replace RAM sticks for you should you get one that produces such errors.

It could also be that one of the pins is not making contact in the slot. Switch the 2 new sticks around in the slots, and try different combos will all four sticks. It may actually start working fine, in which case it was just a bad pin connection.

Hi forum, being reading threads on here for a while and looking at peoples input. Got to say fosterT wins hans down!

I'm in Thailand training and bumped in to a lad with a G74sx, I was like wow I want one of these. So for the last 6 months I've been trying to buy one with the right spec, then the G75 came out and would like to ask the board for their input on a few things to help to decide which to buy.

Should I buy the G74 or G75? Is there that much of an inprovement? Does the G75 operate memory 1600 with 32GB?

I was hoping for something a little lighter but wont be moving around with it a lot, however are there other better options with the same spec?

I'm going to buy used. The price for the G74 is like $700 for a basic model. Is there any models I should avoid or better models I should look for(buying on eBay :/). I'll be upgrading it no matter to SSD & 32GB[/I]

Not being an avid 3D enthusiast, is there any other point in buying a 3D model over the standard?

I've done research already on the majority, would just like to hear other peoples positive opinions.

Do people see any improvement in the SSD over the 7200 rpm drive provided?

Wow, my first post and a million questions. Your either going to love me or.. :/ hate me.

To add to the last thread. I know you can use another external screen with this.. can I use 2 external screens?

:/ forgot.. WiMax! Do I need it! Lol I know it's 4G for cell service however I know there was an option on upgrading to a better wireless adapter. A friend told me that was its only flaw and he'd wished he bought the upgrade.
