q6600 OC voltage temps and testing it

[Sutareteiru]

Hello I am a bit new to overclocking, I have read several articles and tutorials concerning overclocking my q6600. Recently I OC'd my processor to 3.0ghz just for a trial, it loaded up to windows and everything seems fine. However when I first booted it and checked the voltage it seemed a bit high, it stayed at around 1.35, so I manually changed the voltage limit in bios to 1.28 and it stays at around 1.26 now. With that being said, I have attempted several stress tests with the prime number program, assigning 2 cores to each instance of it running, I ran 2 of the program at once, and it always seems that my core 3 just shuts down and creates an error within 20 seconds. Also ever since I updated my bios version it seems the hardware monitor i use to verify core temps has increased....my cores sit at about 115 F for core 1 around 111 F for core 2 and the 3rd and 4th sit at around 105 F at idle, then jump up about 20 degrees each under load, im wondering if there seems to be something wrong with my processor or maybe its just a user error with assembly? Possibly with the liquid gel for the heatsink.

If your stress testing has a core fail, then it isn't stable at that setting/voltage. You will need to tweak your CPU voltage to get it stable. Remember as you increase your FSB speed, your RAM will be running at higher speeds, so make sure you are running your RAM within spec. As your get close to a FSB speed of 400MHz, make sure your RAM is running at 1:1 to make sure you aren't runnign over specs. You can probably safely increase your CPU voltage to 1.4V as long as your temsp stay OK.

Also, as FSB goes up, your might need to bump up the northbridge voltage a bit as well, to cope with the higher speeds.

Your temps look fine, I try and keep mine below 65C under stress testing. My idle temp is 25C (speedstep enabled) and my full load (small FFT) Prime95 after a while is ~60-62C. So your temp jump is normal and expected. And as the CPU loads/unloads, the temps do change that much and that quickly.

Thanks for the info, when i get home tonite i will attempt to make the tweaks you suggested and let you know the result!
