IBM Xeon X5550 processor module
The IBM 44E5188 is a refurbished Xeon X5550 quad-core processor running at 2.66 GHz with 1 MB L2 and 8 MB L3 cache. It uses a 6.4 GT/s QPI link and fits Socket B (LGA1366) in a 45 nm, 95 W package. The module is intended as a direct replacement CPU for supported IBM System x servers.
Compatible System x 3550 M2
This processor suits administrators upgrading or repairing those specific System x models. It will not fit systems requiring a different socket, QPI speed or thermal envelope. Buyers needing a newer architecture or higher core count should look elsewhere.

Questions about this item
Will the 95 W TDP of the Xeon X5550 become the first thermal limit during sustained loads?
The 95 W TDP is the design power ceiling; under continuous full-core work the processor will hit this thermal envelope before any other subsystem limit.
How much heat and fan noise should I expect from the 95 W Xeon running all day in an X3550 M2?
The 95 W rating means the server's cooling must dissipate that heat continuously; expect the system fans to ramp to speeds matched to a 95 W load, producing noticeable but typical rack-mount noise levels.
