Core 2 Duo E8400 Issues

I recently tried overclocking my E8400 to 3.6GHz. It's not surprising that it was not stable, but now my PC crashes even when the CPU is at the stock 3.0GHz. I'm afraid I damaged it, though the temperatures never went above 65C and I never had the Vcore over 1.3V. I haven't changed any BIOS settings that would cause problems.

It has only crashed when running Prime95 through RealTemp, towards the end of the cool-down test. It hasn't crashed in other circumstances though.

Is it possible my CPU is damaged? If not, what could be the problem?

65 centigrade is a little high for the C2D series, have you cleared the CMOS?

The fan failed on mine and it shutdown when it reached approximately 100°C; therefore 65°C shouldn't be an issue.

I agree with your recommendation to clear the CMOS.

I doubt it's the CPU, I'm thinking it's the RAM. Did you make any changes to that when you made the OC? And what type of RAM do you have?

If you didn't change the ratio you could have easily pushed your RAM way too far when you raised the front side bus and it died.

Try clearing the CMOS first though.

I agree with calinkula about the RAM, a possibility.
