Earlier, I reported an invalid DIMM population error with my S2600CP4 server board here. Now that I have the REG ECC DIMMS on-hand, I'm having a different issue.
I'm now getting the following errors:
3 long beeps while the LEDs are lit for error code EAh "DDR3 channel training error".
5 short beeps while the LEDs are lit for error code D6h (unknown error).
It then stops while the LEDs are lit for progress code B2h "DXE Legacy Option ROM init".
