Hi nelegall,

The L5420 should work in this system. Did you get the CPU’s from us? Do you know which revision they are? Does the server boot fine with the old processors?

When you tried the processors one at a time you had them in socket 1 correct? It is the right processor if looking at it from the system front.

  CPU was provided to us by local reseller.

Do you know which revision they are?
I have no idea about revision.

Does the server boot fine with the old processors?
 Yep, here is Xeon 5130.

When you tried the processors one at a time you had them in socket 1 correct? It is the right processor if looking at it from the system front.
Yep, socket 1. By the way I've tried socket 2 too, same error - "Unsupported CPU combination System halted!".

Here is photo of new processor, I suppose it can help: 

 

P.S. CPU-Z show model of MB is 0YM158 A01 (Chipset 5000X rev12, Southbridge 6321ESB rev09), it's really PE2900 (III)?

Did you update the BMC as well?

BMC motherboard firmware Version 2.5.0, A00, Released 10/15/12, URGENT, *Note, will cause fans to run fast/loud while updating

Windows: downloads.dell.com/.../ESM_Firmware_C6H4X_WN32_2.50_A00.EXE

Can you email me the service tag and I can make sure that it is  2900III

"No. Installing right now. Can it help?"

Because the BIOS and ESM/BMC work together to manage/monitor the system's hardware, updating one without updating the other can lead to odd behavior.

If updating the BMC does not help, try clearing the NVRAM using the jumpers on the motherboard after inserting new processors (boot with jumpers on CLR, then switch back).

BIOS updated to 2.7.0, ESM/BMC updated to 2.50, NVRAM cleared. Still not working.

Did we ever confirm it IS actually a 2900 III?  Josh asked for the Service Tag, but nothing more was said about it.  ONLY the III will take the 5400-series procs. There have been some on here whose systems were mislabeled ... some were previously-owned or offsite/out of direct supervision/control and could have had the motherboard swapped/replaced.  Could that be the case here, if labeled with a III? 

The part number YM158 seems to indicate it is maybe a revision I or II board, not III ... Josh could confirm:

When I checked it looked like a II and not a III, but was an international service tag and I could not confirm 100%
