DFI 790FXB M2RSH and PII 940 stuck on 3.6 - Help

Recommended Posts

I am tryin to get my DFI 790FXB M2SRH and PII 940 to OC above 3.6 but I must be missing some setting in BIOS because I can't get it stable above 3.6.

 

I am getting 3.6 by simply raising the multiplier to 18x and increasing the vcore to 1.44.

 

I have tried increasing the CPU vcore to 1.55 and still can't get stable above 3.6. I use OCCT and Prime95 and get failures abofve 3.6 and although I am using a XIGMATEK Dark Knight-S1283V with (2) 120mm fans my C PU core temps go up to 68 degrees under load.

 

Should I be changing the CPU NB clock ratio? or the HT link frequecny? What about the IH flow control mode under HT link control?

 

There must be something I am missing that is stopping me at 3.6.

 

Any suggestions?

I hear above 60C some of the Phenom II's go unstable just because of the temps (hence why the 1.55v not really helping)

those Phenom's love being cool more than being fed more voltage

Interesting. My board is a 790FX M2RS and I see same clocks. Starting to think maybe it's a DFI thing, not a Phenom II thing. Most people on otherboards can get 3.8 or so.
