Supported processors in the ThinkStation C20 and C20x
Which processors are supported in the ThinkStation C20 and C20x?
As of the writing of this article, the following Intel® Xeon® processors are supported in C20x systems:
E5502 E5503 E5504 E5506 E5507 E5520 E5530 E5540
X5550 X5560 X5570
E5603 E5606 E5607 E5620 E5630 E5640 E5645 E5649
*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.
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.
