Hey all,
I'm trying to get my E8400 (c0) stable at 4GHz with an EP45-DS4 motherboard and Corsair Dominator TWIN2X4096-8500C5D memory. It's almost stable at the moment, there are only a few crashes and the occasional BSOD. It passes memtest and Prime95 with small FFT's, and even passes Intel Burn Test, but fails Prime95 blend. The one thing, which I've read is pretty vital with a 33% overclock in FSB and with 2x2GB of memory at 1066MHz, which I haven't managed is a (decent) increase in MCH core voltage. I can increase it by about 0.06V, up to 1.16V, but at 1.18~1.2V it becomes unstable and any higher than that and it doesn't boot (no display for a few seconds and then resets). I've read that I could need over 1.25V, and I've never read of anyone having problems at such low voltages, so can anybody shed some light on why my MCH is so stubborn?
Thanks,
Shard.
