[Dark-Energy]

Hello All,

I posted a few days ago but didn't get a respose.

Here is my system:
BIOS: F9
GA-EP45-UD3P rev 1.0

E8500 E0 Stepping @ 4.105GHz 1.40625v
PC2-8800 RAM 5-5-5-15 @ 1159MHz

I am trying to optimize my O/C, but if I try to lower my vCore I get a BSOD. Below is my Template:

I idle around 35degC with an internal case temp of 24degC.

The peak I have seen is ~71ish degC during Intel BurnIn test (linpack) and only about ~64-65degC with Prime95 Small FFT.


Can you help me to get a cooler running chip?

Thanks,
-Jsunn

Clock skews seem a bit high, especially for a dual. Try lowering one or both of them. Lower or up your cpu reference, and your VTT is too much, 1.28-1.30 is plenty, or you're doing something wrong. MCH Reference is picky on these boards too so try changing that around. Not all boards are the same though.

And set your VTT to 1.2 and your CPU reference to .760 and MCH reference to .70, then raise your VTT back up and it should scale. Good luck
