  • 24 threads for multi-threaded applications
  • 50 MB L3 cache reduces latency
  • 100 W TDP fits existing server cooling

Processor upgrade for HPE ProLiant DL360 Gen10

This HPE kit contains an Intel Xeon Silver 4214R processor with 12 cores running at 2.40 GHz. It targets administrators refreshing a compatible Gen10 server who need additional multi-threaded capacity for virtualisation or database workloads. The 24 threads and 16.50 MB L3 cache support parallel tasks in dense rack environments.

Installation notes and common issues

The processor drops into a Socket 3647 on the system board and is rated at 100 W TDP with a maximum case temperature of 79°C. Installation requires the correct heatsink and torque sequence for the specific chassis; omitting the VRM upgrade kit where required is the most frequent cause of POST failures. Firmware must be current before the new CPU is seated.

Capacity headroom and limits

At base frequency the chip delivers steady throughput for typical enterprise loads, while the 3.50 GHz turbo provides burst headroom for short spikes. The 14 nm process and 100 W envelope limit sustained all-core speeds under heavy compute, so workloads that saturate every thread continuously will hit thermal and power ceilings. Memory channel population and BIOS power profiles also influence realised performance.

Questions about this item

How can I confirm the 12-core Xeon is running at its 2.40 GHz base clock after installation?

Check the processor frequency in the HPE iLO interface or BIOS; it should report 2.40 GHz with all 12 cores active under load.

Does the P15977B21 package include a heatsink or thermal paste, or must I order them separately?

The upgrade kit contains only the processor; a compatible heatsink and thermal compound for Socket 3647 must be purchased separately.

Should I choose this 12-core 4214R or a higher-core-count Xeon for my HPE ProLiant DL360 Gen10?

Select the 4214R when your workloads need 24 threads at 100 W TDP; higher-core models increase thread count but also raise power and cooling demands.
