Hi, 

I bought a second hand PE 2950 Gen 2 with a single, dual core E5130 CPU. 

I done a lot of research online regarding the different server generations and supported CPUs, and bought 2x Xeon 5345 processors which according to everywhere I've read online, this server should support after upgrading the BIOS to 2.7.0 and BMC to the latest, which I did.

When I boot the system, after I get past BIOS loading bar and the hardware initialisation, I get a CPU configuration unsupported, System halted" error. I've tried resetting the NVRAM, left the bios battery out for 30min etc, but still the same. Any help would be much appreciated, as I don't want to buy more CPUs if I dont have to :)

EDIT: The service tag is <ADMIN NOTE: Service tag removed per privacy policy>

 if that can help

Thanks
