Hey guys

I have a spare Athlon 860k fm2+ and I have attempted to put it in around 3 asrock fm2a58m-hd+ which is a FM2+ socket but I either get no post at all, or doesn't get past bios.

I tried it with a cheap 5600k and it posts and works perfectly.. could this be a faulty CPU or is there compatibility issues I'm failing to see?

Thanks!
