Refurbished IBM Xeon X5550 processor in anti-static packaging

IBM Refurbished

IBM 44E5188 Xeon X5550 2.66GHz switch module

SKU CH-D51M-HX4PC MPN 44E5188

A refurbished quad-core Xeon processor running at 2.66 GHz for IBM System x3550 M2 and x3650 M2 or M3 servers

  • Quad-core Xeon processing at 2.66 GHz for parallel workloads
  • 8 MB L3 cache speeds data access in multi-threaded tasks
  • 4 GT/s QPI links processors for scalable system performance
  • Validated for System x3550 M2 and x3650 M2/M3 servers

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.
