Are all of you guys at 4.0ghz fully stable when running Prime95?
The reason I ask is because I was initially able to run a few 3dMark Vantage bench marks without any issues at 4.0Ghz even at 4.2Ghz, however if I run Prime95 I get hardware calculation errors.
I lowered my RAM speeds, from 1600Mhz to 1400Mhz and I still got error in Prime95 when Oc'ing my chip past 3.8Ghz to 3.9Ghz.... so I don't think the RAM is at fault. However my RAM Voltage manufacturer spec is 1.35v and my BIOS is auto detected it at 1.50, and I increased it to 1.55 thinking that might be the problem. I wonder if to much ram voltage would cause it to be unstable.
Any wayâ€™s, I had to bump down my OC to 3.8Ghz to get Prime95 to run without any errors for aprox 1 hour. I think I'm also stuck leaving the CPU voltage at 1.55v, (1.42 BIOS) (1.55v under load)/(Vboost). I guess itâ€™s not so bad since if the CPU isn't under load the voltage stays at1.42.
I have this weird feeling that I canâ€™t get past 3.8Ghz stable in Prime95 because of this board or the Vboost option that I canâ€™t disable in the BIOS.
Like I asked initially are all of you guys really stable on Prime95 at 4Ghz? or are you only fully stable within games and bench market software ?
