OC My i7 940

[stevehookem]

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

There is alot of info in these threads about all that. Everything you need to know is here, just start reading.

[stevehookem]

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!

Thats great! Welcome to the club Steve. Did you end up staying with the 21x multiplyer? It was nice to talk to you and glad I could help.

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....

Did you install the chipset drivers that are on the CD that came with the MOBO? My FSX computer is hard wired to my wireless router but I have read where some wireless adapters having issues with x64. If you have all the chipset drivers intalled I would go pick up another card and see if the problem persists. If it does then you know it is not the card and something else, if it goes away then thats one problem solved. Also I would try another pci slot for the card.

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.

[stevehookem]

I tried disabling the onboard and no luck.

I haven't installed anything from the disc that came with the MB. I forgot I had that. However, my adapters are all USB. I have the Belkin and a Linksys. It seems that neither are supported by XP64. Belkin has a newer model that is. I just purchased it from Best Buy and will pick it up later.

Do you think the chipset drivers will work for this?

[jwenham]

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

[stevehookem]

OK, my original USB adapter is now working after installing the chipset drivers. Cool. I'll just get my money back from Best Buy!

Thanks for that tip! Saved me $50!

The only little issue I have is that it won't reconnect automatically when I reboot. I have to manually choose it from the tray and then it connects.

Also, the sound card is no big deal. I really don't know why I even had that. It's not any better than the onboard sound and much more hassle. I'm leaving it in the old system.

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.

Get your software completely installed including addons.. get the system optimized as per my list including O&O defrag passes

if you are on Vista I can provide a crossover list that matches the items in my XP list

once thats all done.. calibrate you sim via my simforums thread about tuning FSX

when that is finished post for clocking values.. we dont clock anything until our software is installed, system is optimized and FSX is pre-tuned.. then we clock and trim FSX in

I will provide a complete clock list for the entire BIOS including software to test for temps and stability

ok sounds good!

I'd be glad to help! Its not that hard at all. I had to go to a 21x mult to get my clock stable. One thing you will find is that the 940's are not needing as much juice as the 920 in a 3.8 - 4.0 ghz OC. AS far as using the stock HSF that will prob not allow you to go any higher that a OC to 3.2 - 3.5. I was able to hit 3.5 without changing my Vcore at all but that was not stable. the 3.2 - 3.5 range seems to be where you will need to start to up the voltage. I can post my specs but keep in mind what works on one may not on another but at the very least should get you in the ballpark.

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.
