I OC'd my E8400 to 3.91, but it reboots & crashes if I try to get it to 4.0GHz.
What can I plugin or change in the BIOS to get it to boot and run stable @>4.0GHz?
It was orthos stable (@3.91 for about 1/2 hour) before I canceled the stress test, I'd rather get it over the 4.0 barrier first and then stress it overnight.

Thanks
