I have a Dell PowerEdge 2900 server loaded with ESXi 5.0 with an Intel Xeon Processor E5420
. I wanted to add a second processor and house multiple virtual machines on it, so I bought another CPU
of the same model.
For whatever reason, I cannot get the machine to detect the second CPU in the BIOS, ESXi, or anywhere. I've updated the BIOS from 2.2.6 to 2.7.0 and tried use a hardware diagnostic bootable disk to see what the issue is. I took the new CPU and put it in Slot 1; the machine booted fine. When I put the old CPU into Slot 2, I got an error message on the LCD by the power button "E1410 CPU 1 IERR".
Does anyone have any idea what might be preventing the CPU from being detected? Thanks in advance!
