Q6600/680i newbie

post #1 of 9
Thread Starter 
Here's what I have;



I have tried a little on my own by reading how others have OC'ed similar setups, but I keep getting BSOD, or boot failure. I have followed every step in the Nvidia n680i SLI overclocking guide, no go.

My pwr supply is a pc power and cooling 750 watt. CPU is cooled by an Ultra thermoelectric cpu cooler, runs at 25-30c or so. The ram is Corsair Dominator 1066.

Would someone walk me thru OCing this to 2.6ghz or so, I cannot get it past 2.5ghz without BSOD or boot failure.

I have returned all bios settings to default awaiting help.

Thanks,

Cdr

Have you tried raising your vcore? also do you have the revision of the 680i, (A1 or T1)?

This is a guide that tells you what to turn off in your BIOS to allow a stable overclock.

^ What king said. You'll need to raise your vcore to handle the increased clock speeds.

King; It is an A1

Greg; followed instructions in guide

I have it running at 2.6. The only thing I did was raise the fsb to 1157.

No noticeable change in cpu temp.

vcore 1.35 from 1.2
fsb 1.5 from 1.4
memory 2.2 from 1.8
SPP 1.5 from 1.4

Seems to be stable at this.

Thanks

I was able to put my Q6600 to 3ghz without even touching the vcore. Does your board have a major vdroop or something? I don't see how our boards being different could make such a big difference as making it BSOD for 200mhz increase...

This probably wont effect you POST but have you disabled EIST (enhanced Intel Speedstep Technology), Thermal control, and/or any other form of voltage/core clock modifying setting. They will underclock your processor so there best left off.

There Is 2 factors I can think of that could be causing this assuming all your hardware is in working order.
Incorrect CPU fsb or lack of CPU voltage. What is you reported voltage In the bios?
Incorrect ram divider or lack of voltage. What is you bios reading for voltage?

I would set your cpu to 1.4 volts to eliminate that factor. Don't worry It wont hurt It.
Set your Dominators to 2.2v, they still have a lot of headroom.

Oh and welcome to the forums.

Thanks for all the help.

I have it running stable at 2.6, I'll tweak some more the next time I return home (OTR truck driver).
