So it has been confirmed that an AM3+ CPU physically fits on an AM3 socket. But the thing is that will it work? I have this question in mind long before. Will the motherboards which does not have a BIOS update support AM3+ CPUs? I recently heard from a shop in the computer market that my motherboard will support it. I have the Asus M4A88TD M-EVO AM3 There is an identical board-Asus M5A88 M-EVO AM3+. If you have personally tried the AM3+ CPUs on the AM3 socket, please share your experiences. Thank you.
