post #1 of 7
Thread Starter 
Hi folks

Right now, my rig is at 4.3ghz. Passed 20runs of linx

vcore 1.38750
cpu vtt 1.275
cpui pll 1.875
qpi pll 1.375
dimm volt 1.65
ioh vcore 1.35

rams
1067 / 2:8 @ 1642mphz
6,6,6,17,74,2T

ambient temp 31c
idle core temp 44c, max core temp 80c

I want to get 4.5ghz, but even if i up the vcore to 1.4 and lower the ram speed, still wont boot.

help needed !!

p.s this is my first intel rig thus me not that familiar yet...

so you're currently running 1.38v for 4.3, 4.4 will require at least 1.456, usually after 4.4 there is a huge jump in volts to make 4.5 stable. so you may need around 1.52v on that chip. smile.gif ... you maybe pushing to your limits you're already hitting 80c which is the max you'd want to do on these chips. you might be asking to much... i personally would run a nice and cool and stable 4.2ghz trust me you wont have anything to gain from going from 4.3 to 4.5. Other than a higher benchmark number, i guarantee you if you ran 3.6ghz @ 1.14v you'd see no difference in gaming or processing if you were to run 4.5ghz @ 1.52v.


FYI 950/960's aren't the greatest clocking chips, i don't ive ever seen any of these cpus's running 4.5 stable under 1.5v.

80*C You should not raise the Vcore anymore.
Unless you don't give a c rap about your stuff.

just my two cents.

since not much performance diff between 100-200mhz, shld i clock back to 4ghz and make it more streamline?

yeah for sure... its all fun trying to clock higher and higher, the fact is some chips can do it and some chips can't ...
but 1.38v is great volts for that chip at that clock! and is the best it probably can do thumb.gif good job

your max safe clock would be 4.4@ 1.456v but watch the temps biggrin.gif
