Prime95 Crash Help.

post #1 of 3
Thread Starter 
Alright, I've taken my P4 640 to 4.1Ghz on a 915P Chipset, which is quite impressive already for this motherboard. I'm running a 256.5FSBx16 ~ 4.105Ghz, 1025Mhz FSB, DDR405 @2.5-3-3-7, 1.4000vcore, 1.6v chipset voltage, but I still manage to get errors in prime after only a few minutes. 100% full load while Dual-Prime does run takes me to ~57*C.

What must I try to get this prime stable? I know that this chip can handle the speed it's at, it was dual-prime 24hr stable at 4.005Ghz just last night. I tried raising the Chipset voltage from AUTO to 1.6v (max) but still no luck. Do you guys think I need to change the "FSB Termination Voltage" or raise the vcore another notch?

More vcore might stable it out, but with those temps and already at 1.4 I can't personally recomend you try it unless you don't plan on keeping that CPU for more than a year or 2.

If it helps, that is darn impressive on that chipset.......

Yea I think I'm going to drop back to 4.005 @1.4 to keep it running fairly cool for now (it only hits ~53*C dualprime) and then when I get some new cooling - BTVX/Scythe Ninja/AC Freezer7 Pro w/ FM91, then I'll see how high I can go.

I might do a suicide shot just for kicks now though and try 4.2Ghz to join the 1Ghz club
