I have a 4600+ X2 manchester 939 on asus a8n-sli and get instability when overclocking even slightly. The mobo has latest bios 1014 and my driver has been updated as well.

I am running 4x512 ddr400 set to 333mhz in bios. Everything else for mem is auto.

I set HT multi to 4x

Set voltage to 1.4 for CPU

Set CPU to 233 w/12x for 2.8

It fails PRIME 95 in first 5 mins.

Please help! I'm new to overclocking but am learning fast!
