Having problem OC proc above 4ghz (see specs below)
It seems the memory doesn't like running at it's standard speed (1066) & even if i lower it, i always get blue screens / no boot as soon as i go over the 4ghz mark.
I'm using Ket's latest BIOS (used most previous too) but i can't seem to get stablized.
Is this because i'm using all mem slots or am i just asking for too much of an overclock - with watercooling & various vdimm, processor i think is not the problem?
Mem tested RAM - all ok

Opinions & advice welcome
