Hi Im trying to hit 4.5Ghz with my E8400 E0
So far I could hit 4Ghz with ease but Im stuck at 500 X8
Even if I try to change my multi to X8.5 I'll have to raise a lot of voltage.

The problem is that when I raise my vCore to very high for X8.5 (v1.36+) my computer become really unstable. Symptoms are
1. Random BSOD
2. Could run p95 small fft for hours and when I restart it can't even do 10 sec. (random)
3. When I could do the small fft test for hours, I couldn't even do 1 min blend,even though I didn't even touch my memory settings and voltages that were rock solid when I was doing 4Ghz on the cpu.
4. When I bring down my vCore and multi to X8, the memory becomes stable again.

HALP!
