Refurbished IBM Xeon E78837 Server Processor

This IBM 69Y1894 is a refurbished Xeon E78837 server processor with eight cores running at 2.66 GHz and 24 MB Smart Cache. It fits Socket LGA1567 platforms and draws 130 W. The part is suited for maintenance or expansion of compatible legacy server systems.

DDR3 1066 Memory Controller and 6.4 GT/s QPI Limits

The integrated memory controller supports DDR3 at 1066 speed only, so faster or newer memory generations cannot be used. System interconnect runs at 6.4 GT/s QPI, which caps bandwidth between processors in multi-socket configurations. Builders needing higher memory throughput or a different socket must select another platform.

Highlights

  • Eight cores handle heavy multi-threaded workloads
  • 24 MB smart cache accelerates data access
  • 4 GT/s QPI enables fast inter-processor links
  • DDR3-1066 memory controller supports high-capacity RAM

Questions about this item

Should I choose the 24 MB cache version or a smaller cache option?

This processor comes with a fixed 24 MB Smart Cache; there is no smaller cache variant available for the E78837 model.

What does the 2.66 GHz clock speed mean for actual server workloads?

The 2.66 GHz base frequency runs across eight cores, delivering consistent throughput for multi-threaded server applications when paired with DDR3 1066 memory.
