HPE 817959-B21 Intel Xeon E5 2690 v4 14 Core Processor Kit

Overview

The HPE 817959-B21 is a full processor upgrade kit designed for deployment in HPE ProLiant Gen9 rack servers (for example the DL380 Gen9 series). It features the Intel Xeon E5-2690 v4 CPU with 14 physical cores and 28 threads, a 2.6 GHz base frequency and up to ~3.5 GHz turbo speed — ideal for virtualization hosts, high-density compute clusters or general-purpose enterprise rack servers. The kit includes the processor, heatsink/fan assembly and necessary mounting hardware so you can drop it into a compatible platform and reuse your chassis.
In real-world operations, this enables an IT team to boost compute density without ripping out the chassis: you retain your existing server rack, storage/power infrastructure, and upgrade only the CPU layer. Thanks to support for Intel’s Broadwell-EP architecture, high memory bandwidth, multi-threading and high core count deployments are feasible in a dual-socket configuration or even single-socket cost-optimized build.When working in a data-centre in Lahore, Pakistan (or similar locations), this kit offers a cost-effective path to extending a Gen9 architecture rather than moving immediately to the latest platform — especially in use-cases like VMware ESXi hosts, application servers or branch consolidation nodes, where raw core count and thread density matter more than cutting-edge architecture.The HPE kit ensures compatibility with HPE ProLiant Gen9 firmware, iLO remote management and HPE’s service ecosystem, simplifying fleet upgrades and lifecycle management.

Key Features

• 14 physical cores / 28 threads: excellent concurrency for VM-dense hypervisors or multithreaded workloads.

• 2.6 GHz base clock with up to ~3.5 GHz turbo: balances high throughput and strong single-thread bursts.

• 35 MB Intel Smart Cache shared across cores: reduces latency when many threads access shared data.

• Compatible with LGA2011-v3 socket in HPE Gen9 servers: enables upgrade without full platform migration.

• 135 W TDP: realistic power/thermal profile for a 14-core class server CPU in dense rack environments.
