G74SX-BBK8 running 16 Gb of corsair ram at 1600mhz??

[Red Rose]

The same was said about the corsair and it was not true , I believe that without a bios mod the g74sx would only run at 1333 when all the slots are populated .....

I see. So what if you are no longer under warranty and decide to open up the G74sx to upgrade the CPU with a capable processor (ex i7 2760qm), would it then work without the bios mod? I think I jsut answered my question but I want to make sure. (yes I do know that it would void my warranty).

nope , Dave is using the 2760 and no luck , the reazon why we dont detect true speeds is because the mem controller is not up to date so without a bios mod either official from asus or if somobody here tweaks it we wont b able to get true speds .

Im sure it would. The mobo seems capable of handling quicker processors so Im sure it would handle higher clocks on the memory. I think with the 2670, we're just wondering into uncurtain waters.

I went there not to buy an Asus laptop, but to see what they offered in their G74 variants. I figured if they could do it, we should be able to. I asked them how they are able to run 32GB Ram when the Asus website states it only supports 24GB. Others in this forum also questioned it since these 3rd parties added more then the supposed max. They told me I would need an OS that could handle more then 16GB Ram and a processor that could handle it. There is another thread where a forum member decided to take it into his own hands and try for 32GB and had success. So he was the first to do it and should get credit. I just followed him and did the same since it was possible.

The 1600Mhz problem though, I have a feeling it is limited to our 2670QM. I have a feeling with a processor designed to support it, it should be easily done in this laptop. I just think the memory controller in the 2670QM is our bottleneck in cases with stock processors and the G74. I will try once I have the funds for 32GB @ 1600Mhz. If it runs at 1333, Im fine with that.

Ahhh thanks for the explanation. I was wondering why the BIOS was such an important factor in all this because I personally have never wanted to mess with the BIOS considering how many times I've read on here with brickign and everything.

@MrRuckus So let me get this straight, the g74 is able to hit 1600Mhz as long as we do not have all 4 slots filled. So what I am getting is, either to use 2 slots with either 1600 or 1886 sticks of ram, or I can use 4 sticks at 1333 ram. BTW I'm assuming your running the 24 GBs of RAM with windows ultimate or professional (I forgot) since HP supports only up to 16GB. Im also assuming that those 24GB are running at 1333? Your pictures seem to contradict what is going on.

EDIT: Just saw your post after I typed this one up. So I am guessing you did upgrade the OS?

The 2670 is more then capable of 1600mhz the one that is caping us at 1333mhz when all the slots are been use is the bios . But im hopping that someone with the enough bios knoledge will get us over the line.

while i clearly find this to be the most interesting thread on this entire board, my question would be this: if you can obtain 1600 mhz speeds by just using two slots of 8gb chips, then why would you even want to use four slots of 4gb's? i do understand that some on here want to use all four slots to have the 32gb's of ram running, and so being able to use all four would help in this venture, but it seems many on here are happy with just 16gb's of ram, and for those, why would this be a problem if you can use the two slots to get what you want? or am i missing something...?

Actually I question that myself. I have heard that there really isn't taht much performance increase from 1333 to 1600 (maybe 5-6% from what Ive read but it could have improved). I do not know about 1886Mhz RAM. I have seen someone here on RoG that actually utilied the full 32 GB's because he needed to open up large images for astronomy or something. But I asked myself the same question since I doubt gaming, for me, utilizes all 12 GBs so I might consider just getting 2 sticks of 1886Mhz RAM instead since I have recieved confirmed reports that any 2 sticks will run at max speed. It just hates 4 sticks.

i guess the only answer i can give you is that we want all of our 4 slots to work at the right speed , i personally i was only using 2x4gb at 1600mhz but after installing my other 2 , my graphics card score went up to 7.2 so im guessing that there is a benefit on using all 4 slots BUT it would b even better to have them work at their true speed.

Yeah, thats here. I bought and used 1333 MHz stuff (back when I tried this 8GB SODIMM sticks at 1600 MHz were not yet available) so I can't say for sure, but I suspect even with a core i7 2820 in there 4 sticks of 1600 will clock only to 1333MHz. I mean why would two sticks work at 1866MHz with even the lowly i7 2630QM but not four? The IMC in the 2nd Gen i7 is very tough and overclocks a long way, so if it doesn't work on the 2630/2670 I think it won't on the faster chips...I think its a BIOS limitation. But I'd really love to be shown wrong!
