x2 3800 - Lack of power

[Cody]

I have recently changed from an Opteron 148 runnning at 2997Mhz to a x2 3800, whenever I go above 2.25 Ghz the PC works for about a minute and then shuts down.

I believe this could be a power problem as the previous owner had it running at 2.7Ghz with 1.472v - the same as I am using :

I currently have a Akasa 480W Pax Power.

I have a 6600GT, I was getting power warnings from it before when I had the Opteron in, they were in Windows not when playing games.

I will check the BIOS. It's just shut down when I went on it when I got back from work, even though its been folding all day!

I updated the BIOS and it seems to be a bit more stabler now at 2.4Ghz, I did try 2.5Ghz but then I got blue screens with a 00000024 stop error related to atapi.sys. I looked at this on the microsoft website but I couldn't see anything relevant.

Only cpu-z, I have been running at 2.35Ghz with 1.360v (this doesn't fluctuate. I changed to 2.4Ghz with 1.460v this morning and it shut down after about a minute. Temprature is 42 C under load, I think my Opteron was similar - everyone advised me to get a Swiftech kit but I got the Asetek so I could have the LCD display linked to the pump.

I might just sell it and get another one.

I forgot to mention there is a missing pin one one of the sides and there was a bit of a chip on the core from the previous owner but it doesn't affect the chip at stock. I have had the IHS reattached by welshtom from these forums, as I was struggling to get a decent contact.
