I have a Intel S5000PSL Server mainboard and like to upgrade the CPU's to Intel's E5420.
The online description say that BIOS version 84 or later wil support the series 5200 and 5400 CPU's.
If I put them on the board it wont boot and I receive error codes like:
19A = Fatal Voltage mismatch
There is also the thing about non-refresh board wich is not entire clear for me.
Is this a hardware or software limitation problem?
