T7810 second cpu not recognised
I have two identical single cpu T7810 workstations working fine individually. I have placed the the cpu and memory from one into the other (and vice versa to check) but neither seem recognise the second cpu at the bios level. Does something need enabling or is the second socket disabled?
Any help is appreciated.

Both CPU's are branded as (I popped the cover and removed the heat sinks)
- SR20J (Intel Xeon E5-1650 v3)
Is that enough to go on?

I "think" yes ( using the sw was simpler, I think ). They have both the same stepping. Ok time to dig further.
Do both 7810 have the same bios version ? some bios updates may include updating parts of the cpu microcode ( not just the bios itself ) if I'm not mistaken.

Please check each cpu revision. Those must be identical.

Not sure about that i did run a bios update after installing the cpu.

Maybe check each CPU sequentially (singly) in the target chassis? If they both work in that chassis them this is weird...

I have tried both cpu's in the primary socket and they both work fine.

The cpus are identical in every classification.

Could you check the Revision level of the 2 cpus , using cpu-z ? ( portableapps.com )
To work together, the 2 cpus must have the same revision level, or at most one revision different
