HPE Xeon E7-2870 10-core processor
This refurbished HPE processor upgrade adds a Xeon E7-2870 with ten cores running at 2.40 GHz. It is designed for compatible HPE servers in the E7-2800 series that require additional processing capacity for demanding workloads. The silver interface processor integrates into supported systems to expand compute resources.
Thermals and power in normal use
The ten-core design distributes workloads across multiple threads to maintain steady throughput. Power draw scales with the 2.4 GHz operating frequency under typical server loads. System-level cooling in the host chassis manages thermal output during sustained operation.
Upgrade context and when it matters
This part replaces a failed or lower-specification processor in an existing E7-2800 platform. The jump is worth it when the current CPU limits concurrency for database, virtualization or analytics tasks. Buyers who need a different socket generation or a higher core count cannot use this upgrade.
Highlights
- 10-core processor handles demanding workloads
- 4 GHz clock speed drives responsive performance
- E7-2800 series scales for growing data needs
- Advanced reliability features protect mission-critical data
- Silver finish fits standard server environments

Questions about this item
How is the HPE 643749-B21 Xeon E7-2870 processor installed in a compatible server socket?
Align the processor notches with the socket keys, lower it gently without force, and close the retention lever fully; the step often missed is applying the correct thermal paste pattern before mounting the heatsink.
What maintenance will the Xeon E7-2870 require over its service life?
Periodic cleaning of the heatsink fins and fan intake prevents dust buildup that reduces cooling efficiency; thermal paste should be reapplied if the processor is reseated or temperatures rise unexpectedly.
What thermal limit appears first when the 10-core 2.4 GHz Xeon runs sustained workloads?
The processor will throttle at its maximum junction temperature to protect itself, reducing clock speeds before any permanent damage occurs.
