I'm pretty sure that's the problem, anyway. Here's the rundown: Supermicro X9SCM Mobo Intel Xeon E3 1220 Sandy Bridge Server CPU 400W Rosewill PSU Corsair Vengeance 240-pin DDR3 RAM (2x4GB) I obviously have more components, but even with these bare essentials it won't boot properly. When I power it on, all the fans start up and all the proper LEDs light up, but there is no beep indicating that it passed the POST, and there is no monitor signal sent from the onboard VGA. I tried removing one memory stick, and got the same response. I then removed both just to see what it would do, and it gave me the expected "no memory" beep code. After looking closer at the memory specs and the motherboard manual, I noticed something that didn't match up. The motherboard only lists 1066 and 1333 as compatible memory speeds, and the memory sticks run at 1600. Is that normally a problem? I can provide any more information if necessary.
