I guess I'll give it a shot and buy an extra fan and bracket, and if it doesn't fit then I've got an extra fan for my side panel on the 900. :-P

I don't know if there is much advantage to push/pull.I did it because I like all the blue LED fans. 1 good fan in push is all you need.

Have you disables speedstep or CxE function? Both of these are power saving features.

VCore @ 1.25 V and DIMM @ 1.60 V boots into Windows without a problem. Prime95 again works well on small FTT but instant BSOD on Blend or Large FTT. Still giving the 0x00000124 audio error common with nVidia GPUs (from what I read). 12V rail stays rock steady at 12.18V which leads me to believe it isn't PSU-related.

Just realized I was running Memtest86 v3.5 instead of Memtest86+ v2.11. Must have downloaded the wrong ISO. New test completed 2 passes with no errors/lockups. Should I be worried that my actual DIMM voltage is reading 1.67 V in CPU-Z/E-LEET and my RAM is rated at 1.50-1.60V? It seems my PSU overvoltages a bit because it is set at 1.60 V in the BIOS.

If I do push to 4.0 GHz with the new cooler, do you think adding another GTX 260 Core 216 for SLI would be pushing it for my 750W PSU? It's got 60A on the 12V rail and the single card calls for 36A, but I don't know if using 2 cards would essentially double the requirements.

Well, upon further inspection I found a review including my exact mobo and the TRUE (http://www.hardwarecanucks.com/forum...-review-5.html). It looks like an east-west orientation with the "push" fan mounted from my RAM side will work fine. I've got a 120mm exhaust directly on the opposite side so I don't think push-pull will even be necessary because it would just be an exhaust fan blowing at another exhaust fan (seems like a waste). The TRUE is going to hang off the edge of my mobo by like 2cm, but it shouldn't be a problem because I've got about 1.5 in of clearance before it hits the 200cm fan on the top of my case.

Yeah, that's the first thing I did upon loading defaults. I run High Performance profile in Vista anyway and I don't think those kick in unless you're on Balanced or Power Saver. Might be wrong, though.

It gives me the same stupid 0x00000124 BSOD which was an audio error that I had with my 8600GT on my old rig. As far as I understand things small FTT is more of a CPU test and the others are more for memory, but I don't know if that is flawed logic.

BSOD error 124 is due to too little CPU VTT voltage on that board. I have the same one, just bump that voltage a bit and you should be good. For reference the BSOD error 101 is too little vcore if you get that one at some point.

Excellent. I had it pretty low to begin with at 1.10 V. Just bumping it up to 1.15 V was enough to keep it from BSOD immediately. I've got the Blend test going at the moment and I'm gonna see how that does for a few hours.

Haven't seen the 101 BSOD yet, but just dropping my VCore from 1.30 to 1.25V was enough to drop idle temps by 6 C and load temps by 10 C across all coress. I just can't wait for my TRUE to get here so I can actually start making real tweaks. I'm happy with 3.2Ghz on the stock cooler for now though.

Thanks to all for the quick responses and help! I already love this forum...

Well, Prime95 Blend test went for 4.5 hours with no errors after the increased VTT.

My system is now stable with Prime95 on all 3 tests and Memtest86+, but here is a new issue: I'm getting random restarts when playing WoW. No warning, no graphic artifacts, no BSOD, nothing logged upon restart of system. Of all games, I wouldn't think something as old as WoW would cause issues especially after it held up to the earlier tests as well as 3DMark/PCMark Vantage tests.

I thought it may have been heat or power related, but my 12V rail stays rock steady at 12.18 V, GPU temp only reaches 41 C while playing WoW, CPU temp across all cores around 38 C. This leads me to think that it's not an overheat issue. I knocked the GPU settings back to the stock 576/1351/999 and it still happens.

Currently I'm downloading the newest set of nVidia drivers to see if that fixes anything.

i was having a similar issue while folding (2xsmp clients for 8 threads) after i bumped up my qpi voltage. what do you have yours set at? can you lower it and maintain stability? i think i had mine too high, but i lowered it and it cleared up the issue.

edit: actually, looking at your earlier post for vtt, you may want to raise that some to see if that helps. mine was to high, but if you set yours down to auto, it might not be getting enough

Sounds like an issue I am having. Sometimes when I do a fresh boot I just get past the BIOS post fine but black screen as soon as the login page comes up. Sometimes in windows I just get a white screen of death and i have to reboot to get my PC back. I have tried just about everything you can think of. I think its just the way they all are unfortunately. I have been through 2 motherboards and tried new RAM, GPU, PSU and nothing worked.

hey.... anyone here using the rampage II extreme board... got my 920 to 3.2 stable so far I want to go higher. I was wondering if someone can give me an idea on there voltage set ups...just for a reference guide... thanks much

I've tried, and required pretty much the same voltage as 21x 191.

I'm going to attempt to get a 3.8Ghz stable tonight on less than 1.38v. Would that be sufficient for 24/7 use?
