need some help with some OCing

[CoryP]

Just put together a computer with Phenom II 555 on a biostar a880g+ with a hyper212 cooler. I unlocked the other cores and OCed it to 3.9 . It seemes to be running ok but on all my programs it doesnt give me any core temps, and the 4th core doesnt stay at 100% while running prime95

then your 4th core is probably unstable. how long did you run prime95 for?

Sorry, but you need to downclock those cores to 3.0 or 3.2 or stable.
Also when cores are unlocked coretemp or any other cpu temp reading utility will not give you readings on your cpu.
Make sure your system can handle the unlock cores, if it cannot, you need to turn them off and not risk damaging your phenom ii 555 later on down the road.
