HPE 817935-B21

Intel Xeon E5-2637 v4 Quad-Core Processor Kit

The HPE 817935-B21 is an enterprise-grade Intel Xeon E5-2637 v4 processor kit optimized for HPE ProLiant Gen9 systems like the DL380 G9 With a high base clock speed, quad-core architecture, and enhanced cache, it's ideal for workloads demanding strong single-threaded performance and virtualization capabilities.

Features

Built on Intel's Broadwell-EP architecture, the Xeon E5-2637 v4 delivers a potent 3.5 GHz base clock rate and can boost to 3.7 GHz. While featuring just 4 cores (8 threads), its high frequency makes it exceptional for applications that don't scale across many cores but need fast execution per core×think single-threaded database operations, real-time analytics, or serial compute tasks.

Advanced Options

The processor kit includes necessary cooling components×heatsink and fans×ensuring optimal thermal management in the 2U rack chassis. Connectivity via FCLGA2011-3 socket and compatibility with HPE's BIOS and platform firmware simplifies integration within ProLiant DL380 Gen9 or similar systems.

Product Key Features

• 4 cores / 8 threads, base 3.5 GHz with up to 3.7 GHz Turbo

• 15 MB Intel Smart Cache for high-performance single-threaded tasks

• QPI interconnect at 9.6 GT/s, 2 links

• 135 W TDP with included high-performance heatsink + fans

• Socket FCLGA2011-3, compatible with HPE ProLiant Gen9 servers (e.g., DL380 G9)

• Supports virtualization (VT-x, VT-d), AES-NI, Hyper-Threading, TSX-NI

Reliability & Performance

Rated at 135 W TDP, this kit offers a balance of thermal efficiency and performance. It includes Intel RAS features plus full support for virtualization extensions like VT-x, VT-d, and TSX-NI.
