Problem - C20 CPU Upgrade X5690 130W CPU

[JoT]

Hi Lenovo Forum,

I just upgraded my CPU to 2 High-End Xeon X5690. I upgraded the fansink for the 130W CPUs. I updated the BIOS to the last Version. 61jy48

But after installing and a restart the C20 tells me that 130W CPUs are not supported.

Any Ideas????

regards JoT

130W CPUs are supported on C20x systems, but are not supported on regular C20 systems.  The CPU VRs in C20 are designed to handle CPUs up to 95W TDP.

Thank you psuturtle for the quick answer. If i upgrade my chassis incl. mainboard would it be possible to work with these 130W CPUs?

you would need either a C20x motherboard with rear port bracket or a full C20x system.   if warranty is a concern than a full C20x system would be your best choice.

Problem solved, I ordered a C20x Workstation without any Hardware from a Demo Pool. Than inistalled my CPUs and everything is running. Thx for the replies!

But i think that in the "which CPUs fit in the C20 thread" should be aounced that the 130W CPUs are only supported in theC20x versions!
