*130W CPUs are not compatible with C20 systems, only C20x, due to the lack of CPU VRMs on the planar necessary to handle the higher power requirements.   C20x systems support 130W CPUs listed above without issue.

 

Before performing any upgrades, please be sure to download the latest BIOS revision for the C20 and C20x available here: http://support.lenovo.com/en_US/detail.page?&LegacyDocID=MIGR-72168

 

Note: If adding a second processor to an existing one, stepping revisions of each processor must match for compatibility.  Subsequently, two procesors added simultaneously must also match stepping revisions.

 

For the most current list of supported processors as well as installation instructions, please refer to the C20/C20x Hardware Maintenance Manual available here: http://support.lenovo.com/en_US/detail.page?&LegacyDocID=MIGR-75550

The 'L' series CPUs are selling dirt cheap (a pair of L5640's can be had for $130USD) and would be great for a homelab - are they completely incompatible, or just unsupported?

Also, the L5630 is listed in the Maintenance Manual as an FRU - is this correct?
