I have the sc1435 server and it worked well with 2 2374 Opterons (bios 2.2.5). I also tried with 8389 (2.9GHZ) and it works with no problem. Recently came to my hand Operon 8393 (3.1GHZ) so tried to upgrade to this processor but it was unsuccessfu, however it worked fine on one processor. Than i tried to put back my two old 2374s but it didint want to boot with them and similar works fine on one processor. During boot fans initially slow down than go on max speed. Any idea what it can be ?? Is it possible that 8393 damaged the MB so it work only on one processor now ??
