I've got all the hardware working--booted up the first time! I've installed Windows XP 64 and let it run overnight.

This morning I get up and have a blue screen with an error that mentions "sysaudio.sys" as the problem. I tried removing that driver and it still won't boot. I pulled out the Creative audio card and now it will boot. However, I have messed with some devices so I am currently reinstalling Win XP just to start fresh.

Once that finishes, I want to OC the i7 940. I have the ASUS P6T Deluxe with 6gb OCZ Gold 1600 DDR3. I would like to get to 4ghz if possible. My cooler is the True 120 1366.

I am not familiar with the BIOS for this board. I have only used nVidia based boards before. Can someone post the "enable/disable" functions for each screen in the BIOS? If I can have it all in one place, that would help! I've seen threads all over the place with turn on HT, turn off HT, turn off turbo, etc. I am confused now as to what to enable.

I then need to know exactly what to adjust to get to 4ghz. If possible, I would like to speak to someone on the phone while we go through the BIOS pages. If this is OK, please PM me with a number and I'll call.

Thanks!

Steve

I've been reading and reading. The problem is that much of the information is spread out over several threads.

I was able to speak to Jim this evening and he has me running at 4.0ghz and stable. Max temp is 60C! Very nice. I ran OCCT and no crashes at all.

Thanks for the help Jim! This looks like a good one!

Yep, lower the CPU voltage one step and ran OCCT for the full hour. No issues at all. I tried to reinstall the Creative sound card and the system won't boot at all.

I also am having a problem with wireless internet. I can see the network but cannot connect. I am switching to my Linksys access point. I'll let you know....

Steve, did you disable the onboard sound? If not, that may be causing the crash. Go into the BIOS under Advanced then Config Onboard Devices and DISABLE HIGH DEF AUDIO and see if that fixes your sound card problem.

Its worth a shot! Its possible though that it is not x64 compatible as well. I loaded the drivers on mine.

Jim,

I am almost ready to OC my i7940 with the same set up! Any help will be greatly appreciated!

What is the max I should do with the stock cooler? I wanted to try a minor OC before getting the cooler and new thermal solution.

ok sounds good!

I am going to listen in on this thread if I am not disturbing, maybe also chip in with questions from time to time. My I7-940 system is all set up and what I found puzzling is that while the system always passes Mem86+ testing, boots in Windows and proves to be Prime stable at any overclock - it turns out never stable in FSX in the end. Mostly I encounter reboots in FSX after some half an hour flying even after the system was stable with Prime for several hours. On stock FSX is absolutely stable.

Also am not entirely clear on how to finetune DRam and VTT voltages although as I said my settings prove to be OK with memtest and Prime.

Thank you in advance and I am listening.

Alex

Thanks, I thought that sooner or later someone would pick on that and I tend to believe that there could be some (if not much) effect on general performance however I do not think it has much to do with overclocking stability. I never ever have OOMs and at stock voltages FSX is as solid as can be. I would tend to think that the 64 bit OS would only concern and positively influence a situation with OOMs. Hopefully I am not wrong alltogether.

I have the 940 and this is how I have mine set 100% stable:

CPU Ratio - 21
BCLK - 191
DRAM Freq -1531 using 1600 ram
CPU voltage - 1.34375
QPI - 1.325
Dram Bus Voltage - 1.64

I have tried and tried and cant get a OCCT stable clock using the 22 cpu ratio.
Good luck and let us know how you do with the OC.

Jim

Yes I optimized the QPI. I kept going down 1 notch at a time untill not stable in OCCT then set it a 1 notch above that level. As far as the temp QPI voltage has I did see a very small drop as I was lowering it but nothing earth shattering to make any big difference. The Vcore is where most of the heat is comming from as well as any residual heat from the VC and PSU. Go ahead and go for the 4 ghz settings Nick has posted and optimize from there and see what happens. The settings he gave are very safe and 99.9 % sure you wont hurt anything but OC'ing is a risk and not a 100% sure bet.
