I've been trying my hand at overclocking my 965 recently, and was wondering if you all had any safety tips or advice on getting a higher speed out of it. I am using an aftermarket fan.
For awhile yesterday I had it running at 3.96ghz (18x220) with 1.425V, and it would pass an Intel Burn Test fine, but trying to run Folding@Home SMP client on it crashed it this morning. I've taken it down to 3.85ghz (17.5x220) at 1.425V and it seems to be doing alright.
1) During the burn test, the CPUID Hardware Monitor would show the "CPU core temperatures" reaching about 63C. However, EasyTune6 (using Gigabyte motherboard) shows a "CPU temperature" of less than that - right now while it's folding, the cores are at 48C while the CPU is at 44C. I've heard that it's best to keep the processor temperature below 62C, and think that is the "CPU temperature", but I'm not entirely sure.
2) What kind of voltage is it safe to give these processors? In the spec sheets, it shows that their "nominal voltage" is up to about 1.40V, so I'm already giving it a bit more than normal. Some review sites I've seen have taken it all the way up to a bit past 1.5V - is it common to run the processor that high?
3) If anyone here is running one of these processors, how fast have you gotten it, and what are your voltages? Any other advice?
Thanks for your help. This is the most powerful computer I've built yet, and I'd really hate to fry the processor from my own stupidity.
EDIT: Figure this might help.
