turn off cpu things esit all thos need ht or just gaming?

 

[88EVGAFTW]

Put CPU Pll to 1.8 or lower
IOH Core to ~1.2-1.25
Vtt to ~1.25-1.3
Leave ICH alone at 1.1 or 1.05, whatever ur board defaults to.
Set ram to 8-8-8-24 and 1.65V

I am really thinking the ram is the problem here. Also make sure Uncore frequency (16X or 20X) is twice the ram

The voltage in the e-leet tab is set in bios (different on yours but you get the idea) . All are on auto except the ICH vcore,cpu vcore,Dimm. find your VID and go from there. You may be giving it more than it wants.

No, If your having problems with your temps than yes but other than that try and leave HT on. Thats one of the points of owning an i7

 

[wilkinsb01]

the problem is 3.8ghz @1.2v is stable but dont boot in windows at 4ghz with any voltage

try tighting/looseing memory timings

Do you have turbo enabled?
