Hello,
I recently bought a Supermicro X8DTi-F motherboard and two Intel Xeon 5620 cpus to use with it.

The problem, however, is that the computer will not boot (not even BIOS, no POST beeps, nothing; just fans spinning) with both cpus inserted. The 24 pin and both 8 pin eps power plugs are connected from my Corsair 950W psu.

The computer works perfectly with just one processor inserted in socket 1.
Neither processor, however, works in socket 2 alone. I am not sure if this expected or not - that is, can a dual processor motherboard run with a single processor in *either* socket?

Applying the most recent BIOS update from Supermicro did not affect the situation.

Could someone please suggest what my next course of action might be? I have no idea whether I can mark the second socket as dead or whether there is a different problem.

Thanks!

IIRC dual socket boards require you to use socket 1 if you're only using 1 CPU.

It looks like 56xx series requires 1.1c BIOS, is that what you're on? Is there an option in the BIOS for activating the second socket?
 
How did you fix the issue?
