Hi all,

I was just wondering if someone knows where there's definitive documentation on CPU support in the Poweredge 2950?

When the box in question was purchased it had a single Xeon 5110 (1.6GHz Dual Core, 1066MHz FSB, 4MB L2).

After reading documentation on the series, I understand of course that it (as it's not a 2950 III) doesn't support the 5200/5400 series Xeons (as they're 45nm), but all the BIOS and Firmware documentation I can find (as well as sales documentation from late 2006 / early 2007 when it was purchased) indicates support for the 5300 series in models prior to the III.

The machine is running the latest BIOS (2.5.0) and BMC Firmware (2.37).

On installing a single L5335 (2.0GHz Quad Core, 1333MHz FSB, 8MB L2) in place of the 5110, the system goes through POST, but stops before booting with "Unsupported CPU Configuration. System Halted.". To be clear this is swapping a single CPU for a single CPU, in CPU Socket 1.

I notice that in the BIOS documentation it specifically mentions support for the L5320 (1.83GHz Quad, 1066MHz FSB, 8MB L2)..

Is the issue:

• A genuine unsupported combination (in contrast to what the docs say)
• A quirk of the BIOS? (ie it 'knows' about other 5300 series CPUs but not the L5335)
• FSB? (i.e. if we drop in a L5320 with a 1066MHz FSB, same as the current CPU, will it work?)
• Or do early 2950s not support Quad Core CPUs?

Thanks for any help...
