BSOD with Q6600 and P5N32-E SLI, 680i

post #1 of 6
Thread Starter 
Hi guys,

Was hoping some of the experts here would have some insight on a strange problem I'm haivng OC my Q6600 on a P5N32-E. I've read through much of Robilar's guide and also searched many other threads, but couldn't find any clues.

The main problem I'm having is I get random BSOD when idle. It seems to happen a lot from cold boots or just restarting the PC as well. They're completley random as the PC sometimes runs for days without a hitch, then can sit idle and just BSOD on me. Running Vista 32 SP1 btw.

Normally I would just assume the OC isn't stable, but it passed a 16hr run of p95 small FFT and a 10hr test of blend. I also ran a 16hr memtest run without any errors. It also has never crashed running 3dmark06 or any games, Crysis included. After that kind of stress, you'd figure it'd be stable, but it'll just BSOD on me idle.

My OC sits at:
Q6600@3GHz
333x9 FSB
Vcore - 1.325v, 1.31v in hwmonitor and 1.28v under load
NB - 1.4v
SB - 1.5v
HT 1.2V - 1.35V
CPU VTT - 1.55V
Memory - 2.2v (2GB Crucial Ballistix Tracer PC2-8500@800MHz, 4-4-4-12)

I've disabled all the extras in the bios and my temps are sitting pretty, 35c-38c idle and 55c-60c under p95 all cores (coretmep). Cooling wise, I've got a Zalman 9700NT, stock MB cooling, and plenty of airflow in the case. I don't think the NB is overheating either because they run at the same temp stock as they do OCed.

I've tried all upping the voltages and all different combinations, but no go. I found that this combination of voltages seems to be the "most" stable. I've also tried to loosen the RAM timings to 5-5-5-15.

I know this board isn't the best for OC quads, but squeezing 3GHz out of it shouldn't be a problem, esp if it's passing all stress tests I'm throwing at it. Why would it be BSOD when idle or rebooting?

Thanks!

download ccleaner and see if it's a bad registry entry causing ur bsod. Also what error message are u getting when u bsod. Turn off the auto restart option and post please.

I don't think it's a bad driver b/c whenever I return to stock settings, everything is fine. I know the OC is causing the problem, just can't figure out where the OC is going wrong. I can give ccleaner a shot though.

The error messages are all random. I was writing them down and looking them up afterwards, but i stopped since it was different each time. Sometimes it would give error codes relating to my video card driver, then a sata controller. I'll try to grab one the next time it blue screens again and post it.

Thanks for the help.

have you tried Memtest on your rams..? everytime i overclock my system.. and my ram's speed go higher than it's normally is.. i get bsod.. if its not ram, stress your processor.. if you get bsod instantly..then try finding which part of the voltage is too low..

Yes, I ran memtest for 16hours no errors. This is when I had timings at 4-4-4-12@800MHz, 2.2v. My RAM is rated at 5-5-5-12@1066, 2.2v. I've tried different voltages for the ram and just leaving it on auto settings (which defaults to 5-5-5-15@800, 1.8v). I can't seem to OC the RAM at all on this board. I know the board only officially supports DDR2-800 though. So to rule out the RAM, I've just left it at stock settings right now.

I've stress tested the system for another day now p95 blend and all seems stable, for now anyway. I was running the small fft yesterday for about 12 hours. Right now sitting at 3GHz, 333x9, and ram timings of 5-5-5-15, 1.8v.

The most frustrating thing is I have wait so long to see if it'll actually crash. Just when I think it's stable...BSOD. Any reason why it would pass all the stress testing then just die idle? Never experienced this before overclocking.

So I'm finally back after a few BSOD and some minidumps. I just put everything back to stock settings to see if it really is my OC that's causing the problem. After analyzing the dump files, it seems the culprit is ntoskrnl.exe, Windows kernel (I'm on Vista-32 btw). It stopped crashing when idle and all my last BSOD came when either loading or shutting down Windows. No filename or specific error message displayed during the BSOD, just "Windows has encountered an error..." (I can zip a couple minidumps if you want)

I'm not sure, what do you guys think? Caused by the OC or could it be a corrupt Windows file, driver, antivirus? My installation of Windows was fairly new and clean before OC and my drivers are up to date. The OC also seems stable as per my original post. Should I just try a fresh install of Vista?

I'm debating whether to just trash this board all together. This 680i has given me the biggest headaches trying to OC. I've never had this much trouble trying to diagnose where the OC is failing. I know it's not the best for quads, but still. This board seems extremely picky about ram, voltages (ie. seems to have "sweet spots", more isn't always better), and it's got fsb holes everywhere. I can't post from 334-411, but 412 onwards is fine and even prime stable for a few hours. (412x8)

I was looking at the P5K-E and the Wifi version as well. Seems like a lot of people are having success with the P5K and Q6600. It also seems like a much easier board to OC. Pretty cheap now too with all the new boards now. Just don't want to shell out another hundred or so if it's something I'm doing wrong here and the board is fine.

Sorry for the rant
