I have a Supermicro X8DAH+-F Rev 2.01 motherboard that will not power on.
I have two Xeon E5645 installed and 6x 8GB 2Rx4 PC3-10600R DIMMs installed in the A and B slots for each channel of each CPU respectively.
The fans spin briefly then stop when turning on the PSU and the BMC light flashes, but I cannot power on the computer. The BMC does not appear to request a DHCP address. There are no beeps, but I know the beeper works because it beeps if no RAM is installed.
I've attempted a BIOS reset, but am now at a loss.
The CPUs and RAM were taken from a known-working box.
Is this configuration correct? Is there some way to also factory reset the BMC without the computer "powered on"?

4 beeps with this AMIBIOS indicates a problem communicating with the RAM or a clock generation problem on the motherboard.
In my case I identified a damaged pin on cpu socket one that maps to slot 1, bank 1 of the memory controller.
