IBM 88Y5657 Xeon E78837 2.66 GHz 24 MB 130 W server processor

SKU CH-W987-ZDPY6 MPN 88Y5657

Eight-core Xeon server processor running at 2.66 GHz with 24 MB cache and DDR3-1066 memory support

  • Integrated Memory Controller SpeedDDR3 1066
  • Octa-core Xeon handles heavy parallel workloads
  • 24 MB Smart Cache speeds data access
  • 4 GT/s QPI links scale multi-socket systems
  • DDR3-1066 controller supports high-capacity memory

Eight-core Xeon for LGA1567 servers

The refurbished IBM 88Y5657 brings an Intel Xeon E78837 with eight cores running at 2.66 GHz and 24 MB of Smart Cache. It fits the LGA1567 socket and connects through a 6.4 GT/s QPI link. The 32 nm processor is rated at 130 W and includes an integrated DDR3-1066 memory controller.

Sustained throughput on multi-socket platforms

Under continuous load the 130 W TDP requires adequate server cooling to maintain the 2.66 GHz base frequency across all eight cores. The 6.4 GT/s QPI bandwidth and large shared cache help keep multi-threaded workloads fed with data. Systems limited to lighter duty cycles or single-socket boards will not utilise the full interconnect capability.

Questions about this item

How much heat does the 130 W TDP of this Xeon E78837 generate under continuous all-day load?

The processor is rated at 130 W TDP, so sustained full-load operation will produce heat equivalent to that power draw and requires a server cooler and chassis airflow designed for at least 130 W dissipation.

Which motherboard socket and memory type must I already have to install this 88Y5657 processor?

You need a motherboard with an LGA 1567 socket and DDR3 memory running at 1066 MHz, as the integrated memory controller is specified for DDR3 1066 only.
