HPE 728967-B21 Xeon E7-8891 v2 10-core 3.20 GHz switch module

SKU CH-D7YF-4P67B MPN 728967-B21

A refurbished 10-core Xeon processor upgrade running at 3.20 GHz with 37.50 MB L3 cache for Socket R LGA-2011 servers

  • Electrical Outlet Plug TypeProcessor Upgrade
  • 10-core Xeon processor handles heavy workloads
  • 20 GHz base clock with 3.70 GHz turbo boost
  • 50 MB L3 cache accelerates data access
  • 22 nm process technology balances performance and efficiency

HPE Xeon E7-8891 v2 processor upgrade

This HPE 728967-B21 module upgrades compatible servers with a deca-core Intel Xeon E7-8891 v2 processor running at 3.20 GHz. It targets administrators refreshing Socket R platforms for mission-critical workloads needing high core counts and large cache. The refurbished unit suits budget-conscious deployments where validated compatibility matters.

Thermals power and noise profile

The processor carries a 155 W thermal design power with a maximum thermal specification of 77°C. Server chassis fans handle active cooling so acoustics depend on system configuration rather than the module itself. Power draw scales with load up to the rated TDP under sustained compute tasks.

Upgrade context and fit

This part replaces an existing Socket R LGA-2011 processor in supported HPE servers moving to the E7-8800 v2 series. The jump is worthwhile when applications benefit from 10 cores, 37.50 MB L3 cache and 3.70 GHz overclocking headroom. It does not fit platforms requiring different socket types or newer processor families.

Questions about this item

How is the HPE 728967-B21 processor installed into a Socket R LGA-2011 slot, and what alignment step is commonly missed?

Align the notches on the processor with the socket keys, lower it vertically without force, then close the load plate and secure the lever before attaching the heatsink.

What component will need replacement over time to keep the Xeon E7-8891 v2 within its 77 °C thermal specification?

The thermal interface material between the processor and heatsink degrades with thermal cycling and should be reapplied when the cooler is removed.

At what power level does the 155 W TDP limit throttle sustained performance on the 10-core 3.20 GHz Xeon?

The 155 W thermal design power is the first limit reached under continuous full-load work, triggering frequency reduction to stay within the thermal envelope.
