I have an a Asrock am2nf6g-vsta am2 mainboard with an amd athlon 64 3500+ and i need more mips. Im thinking that a x4 phenom could be a cheap power boost with the beta bios 2.39 but i think that may be that the board is no intended for this processor. Has somebody this combination? How does it go? Benchmarks? Problems? I need all the information you can give me. Thanks.
