Failing prime95 but temps are still ok...

As title says really - When I run Prime95 with the rig in my sig it fails after only a minute or so, but the CPU never really gets over 60-62 degrees in that time. I'm sure there is more headroom with my chip, and since I can't figure out how to unlock the 1:1 FSB

RAM ratio on this new motherboard I've bought, I really want to get as high as an overclock as possible. Do you gurus think I should up my voltages a bit?

My only previous overclocking was with this same chip, but my old motherboard could only get up to 305FSB, so I wasn't exactly "pushing the limit."

Up the voltage

What is it set to at the moment?

Failing prime usually means you're not giving enough fuel (volts) to the chip. So yes up your vcore a bit. However... 60-62 degrees is in the upper limits of what it can withstand.

Well what voltage do you have?

It's not just the temp that makes it failing prime.

I'm at stock volts...1.325 I think it is...

yeh increase the voltage, just make sure the temps aint too high. anything under 1.5v is usually okay i think, unless the chip is running over 70c

Ok - I'm running it now with 1.375 and it seems to be going along good. Coretemp is up to 63-65 degrees and I don't really fancy letting it get any hotter under load. Since my PC2-6400 is running at only 680Mhz it's time to tighten the timing way down. On the old setup I had it running 3-3-3-9-1T @ 610Mhz, hopefully I can get something similar to that at 680Mhz.

Cheers for the help guys.
