Hi all.

i just got myself a AMD Phenom II 955 Black Edition processor. the problem is windows 7 Build 7100 only detects 2 of the processors cores. Task manager only has 2 performance graphs and its certain as Cpu Z only detects 2 cores aswell. how do i fix this? is it something to do with my bios version??
i have a GA-MA770-UD3 motherboard that is bios version "FA"
on the gigabyte support list it shows the AMD Phenom II 955 requires version "FF" or "FD"

heres the cpu support list

so yeah, this maybe fix it ? anyone got an idea?

lol, so i updated my bios just to find out that windows 7 was limiting the processor to two cores... had to untick "number of processors" in msconfig / boot / advanced tab...

what a pain in the arse.

Best solution
