PowerEdge R520 - Fatal Error! CPU core count mis-match, unsupported configuration

PowerEdge R520 server with the riser card for Dual processors. Original Processor that was shipped with the server was an Intel Xeon E5-2403 v2 processor. We purchased another E5-2403, but this one was the original (version 0 essentially). Is this what is causing the error?

Hello

Is this what is causing the error?

Yes, that is most likely the cause of the issue. The processors must be identical. Even if the stepping is different they will not likely work together.

Thanks
