What moptherboard/server board do you have? You need to check the compatibility list for that board.
Dare I mention, it's a Dell precison workstation.
The only information they could give me was "The part number is T312P and it is a basic TPM Motherbaord kit" and "The board holds a Intel Nehalem processor."
So I entered my service tag and they gave a list of processors I could upgrade too.
...to name a few. So I guess I answered my own question.
Is there anything I should be aware of when upgrading?
As long as the processor is listed as supported by your motherboard, there will be no problem at all.
