Hi,

I have a Phenom II x2 555BE which I was able to unlock to X4.
The initial TDP of the cpu was 80W. But after unlocking it the TDP went up to 160W. just the doudle of the original.
My mobo supports TDP of 140W. Should I worry about it????
How do I lower the TDP???
I have not overclocked any of the system components.
Have already replaced the CPU fan, RAM, PSU, GPU and tried but the problem never solves. :??: 

I have a problem with my computer, it shuts down randomly.

CPU: AMD Phenom II x2 555BE unlocked to X4 B55
MOBO: Gigabyte 880GM-UD2h
RAM: Corsair Xms3 1600 Mhz
SMPS: Corsair 750TX
GPU: ATI Radeon HD5750

From my experience unlocking will often times give an inaccurate TDP reading. My unlocked Athlon II gives a reading of 140 TDP when it is actually 125. I wouldn't be concerned as long as it isn't trying to overvolt above AMD specs.

Its more likly due to a core being unstable, my unlocked 550BE reports 180W (its overclocked to 3.7GHz) and is stable. Have you run Prime 95? If not try it.

When I built my system in january 2011 I ran prime 95. It was stable at that time. But from about a month the computer started shuting down randomly without any warning.

The temp are normal. I changed the power supply, ram, cpu and gpu but dint get any outcome. The problem never took a break.
Recently when I ran prime 95 the computer shut down after one and half hour. But I assume that this is nothinfg to do with the CPU or RAM or PSU as I have replaced them all.

I am all left with the board and my hard disks...

Any suggestions???

Thanx for the reply....
