I feel silly not knowing this but I could use some help. I know that socket 939 boards cannot use am2 cpus but I have a Amd athlon 64 x2 3800+ processor which shows on newegg to be an am2 processor installed in an Asus a8n-sli board, which is shown to be a socket 939 board. How is this possible?
hmmm. I had an MSI K9N SLI Platinum board for my 3800+ X2. It was an AM2 socket which, worked well until I flashed the Bios in Windows. Your board is a Socket 939 as you have stated. However, there are 939 and AM2 versions of the 3800+ X2. You have a 939 version. AM2 is 940 pins, so therefore it wouldn't fit in 939 pins. Did that answer your question?
