I have unlocked the cpu to X4 and prime 95 stable for hours at a time. I get random crashes though when booting up or just anytime though. I had voltage to the cpu at 1.325.

I have read that the voltage for the Phenom II X2 555 is 1.4v and the voltage for thePhenom II X4 955 (which it is unlocked to) is 1.5v. Is the voltage too low caussing random crashes? I have turned the voltage up to 1.4 now. I just ran prime 95 for 90 min and with case fans and cpu fan on high, with a max temp of 48-49*c. With the fans all on medium it idles at 33*c and thats how it is right now while I type this in my house that is 75*f. Any help will be appreciated.

Oh also I got crashes when setting ram to 1600. The ram is rated at 1600 so it is not overclocked. I noticed mobo was setting it at 1.55v, and it is rated 1.65v so I turned it to 1.64 as only even values are ava. in bios. So far I am stable, but do I need to adjust any more values like nForce200 v, or HT v, orNB v etc...? thanx

Does anyone have a similar setup, and have any advice for me?

No, I don't see any reason to change any other voltages. The only thing I would like to remedy though, is your perspective on the default voltage for the X4 955. It's not 1.5V; that's the maximum you should put it at. The default voltage for it is 1.35V.

Thanx for the reply, and the info. my asus only alotted 1.3 volts in auto mode, so far at 1.4 v it has not bsod'd all day, and 2 hrs prime 95. We will see what time will hold tho. Might be the 64 bit os that is troubling it.

That's was you call an unsuccessful unlock :P In this case, the two cores you unlocked were locked for good reason. I suggest re-locking the two cores and run it as the dual-core it's supposed to be; see if the BSOD's stop occurring.
