ML150 G3 2ND CPU not recognised

Hi All,

I have just installed a second CPU into this relatively old machine - HP proliant ML150G3
- everything boots normally but it still says 1 of 1 CPU's

I installed a SL9RZ (5110)(Woodcrest Core) which I was under the impression was the same as the original cpu.

Does anyone have any idea why its not recognised at all? Does the Bios need upgrading for two processors?

Thanks in advanced...

If installing an additional processor module, you also must install an additional voltage-regulator module (VRM). Processor modules acquired from HP will include the additional VRM.

To install a PPM or a VRM in a ProLiant server, refer to the Maintenance and Service Guide for that server.

i would recommend to update the firmware on the MB.
