I bought secondhand z620 cpu raiser for my machine, unfortunalty i still dont have second cpu to test with if its working at all. Can I just plug the raiser in without installing second cpu?

I had a z620 with 2X Xeon E5-2690 (8C@2.9/3.8GHz).
I don't think- at least I've never tried it- the system will start without a CPU exactly matching CPU 0 and at least one memory module on the riser board. One of the problems is likely to be that the second CPU fan is not detected and if any fan is missing, BIOS will shut down the system to protect itself plus there will be a fatal memory error without any RAM on the riser board.
Run the sysem without the riser installed until it has the CPU, memory, and importantly, the fans connected. Anyway, it's impossible to install those components with the riser in place. The board has to be on the bench for access. Air flow in the case will be much better without the riser anyway.

Hey, thanks for the answer. I think you right, it turns out that if i unplug risers power from psu it boots fine with warnings about second cpu fan not connected. I just wanted to clarify if it works before i run and buy second cpu. Anyhow maybe someone tested this machine without cpu in the riser?
