Hi Guys!

I have a PH II 925, and I wanna know its potential for OC. I tried it on stock CPU cooling and 3 case fans (and a 500W PSU, 2 sticks 2Gb DDR3, Sapphire HD4670 1Gb DDR3, on an Asus m4a7h-n mobo) and I can't get it stable at anything past 3.1Ghz on stock voltages (I can't crank the V's at this point due to cooling problems).

I am looking at getting a better cpu cooling (and case cooling)along with a 750W PSU, but I want to know if any of you guys here have had the PH II 925 OCced to around 3.7Ghz or maybe even the 4Ghz barrier?

Thanks!

I have my Phenom II X4 925 "Deneb" sitting at 3500Mhz (250x14) w/ vcore at 1.45v. That voltage seems to be within spec, and I am not having any cooling problems; what do you guys think? Chip is stable Prime95 +8hrs (it never did bsod).
I tried lowering it to 1.42 and It BSOD'd.

Currently it is 70F in my house and my CPU is running 30C(89F) at idle. Under load this goes up about 20 ~ 25F So I expect when summer hits here to see temps around 115F ~ 125F. I use aftermarket air cooling.

My MSI 790x - G45 Mobo would auto set voltages between 1.36v ~ 1.41v between 2.8Ghz and 3.2Ghz (230FSB), anything over 230Mhz ~ 235Mhz FSB would be unstable and crash. The Mobo would not raise the "auto volts" over 1.41v; however 1.45v is well within the...
