My motherboard is ZOTAC with NVIDIA 8300 chipset, which sports an AM2+ processor socket. I heard that AM2+ socket (with 940 pins) is also compatible for use with AM3 processors (with 938 pins). I have upgraded the BIOS downloaded from Zotac for supporting X4 Phenom-II processor. I wish to know if the AM3 processor X4 Phenom-II is compatible with my motherboard? Please clarify.
