i just bought an amd x3 720BE

part number is 0904

but i changed my bios acc to auto, nth happened (GA-MA790GP-4UDH)

no black screen or 3 cores - 4 cores

system booted like normal

does this mean my cpu have a failure 4th core?

thanx

the 904xxxx suppose to unlock the 4th core with ease for the 790 chipset with the ACC on auto. most likely it failed. here read more about it. http://www.guru3d.com/news/phenom-ii...-the-4th-core/
