Unsupported cpu combination. Please install cpu1/2
I have the aforementioned error on my r815 server.

Yes. CPU slot 1 must be populated, but BOTH of the CPU's should work in that slot. If both work there, then put a second CPU in slot 2. If it fails with slot 2 populated, then the slot may be bad.

Ok, they are the original cpus that came with the system and I just started getting this error today. I will try your troubleshooting steps and update. Is there a way to run the system with one cpu? (There are two currently)Rwardsunny

I re-seated the CPU in slot 2 and the server started to work again. I ran diagnostics on the processors but it didn''t return any errors. Any idea what could be the root cause?

Hello
It indicates the combination is unsupported. The CPUs must have matching specifications. If there is a difference between the CPUs in required specifications then the combination will be unsupported. This can be due to an unsupported CPU model combination or a faulty CPU.
If one of the CPUs is experiencing issues then it may not be coming fully online. If the CPUs are of the same model then I suggest testing them one at a time in slot 1 to verify they are both functional. There are troubleshooting guides and other information in the documentation on the system support page.
