I just upgraded my old processors for 2x5400, now the computer wont boot. It just jumps into the bios telling me that there is a processor mismatch voltage error. What is this? .. Its the exact same processors. Now im back to runnig my old 2 core processors.
Appriciate any help.
When you have this error message in the BIOS '19a - voltage mismatched', this is because you have a non-refresh board. It will never go this error message as the non-refresh is not meant to work with 45nm processors, they work only with 65nm. So unfortunately, there is no fix for this. At least your one is working, in some cases it does not boot at all.
Even upgrading the bios, it wont make the error message disappear.
One thing only to be 100% sure, check the pba number of the your board if it is non-refresh board and if your cpu is 45 nm. Other than this, i dont have any suggestions.
Refresh board has a 'R' at the end.

Chech your board and you should see a small white label with barcode on it. There should be a PBA # in 6 digits - dash - 3 digits format. If it's E11034-xxx or E11030-xxx then your board supports Xeon 5400 series. Otherwise your hardware doesn't support the processor.
I did look at that list but apparently not close enough. So what i need is a S5000XVN with a R at the end, aka the S5000XVNSATAR? I wish intel would have been a bit clearer in that case.
