HPE 805351-B21 32GB DDR4-2400 Registered Memory Kit

SKU CH-JXXZ-29B1N

A 32 GB DDR4-2400 registered DIMM with CAS-17 timing for HPE ProLiant Gen9 servers

  • TypeRAM Module
  • High capacity for demanding server workloads with 32GB module
  • Reliable operation in HPE ProLiant Gen9 systems via SmartMemory authentication
  • Low latency response using CAS-17-17-17 timing
  • Stable data handling through registered dual-rank x4 design
  • High-speed performance at DDR4-2400 frequency

32GB DDR4-2400 Registered Memory Kit

This single-module kit delivers 32GB of DDR4-2400 memory with CAS 17-17-17 timings. It uses a dual-rank x4 organisation and registered buffering for signal integrity. The module is designed for HPE ProLiant Gen9 servers and compatible Apollo, Synergy and Blade systems.

Build integration with HPE Gen9 platforms

The registered design reduces electrical load on the server memory controller, allowing larger total capacities across populated slots. HPE SmartMemory authentication unlocks extended performance features through the system ROM. Buyers needing unbuffered DIMMs or non-HPE qualified memory cannot use this module.

Sustained operation in virtualised workloads

The dual-rank layout and registered signalling maintain stability during extended virtualisation and large-database sessions. HPE qualification testing targets continuous uptime requirements in data-centre environments. Systems without Gen9 SmartMemory support will not enable the extended performance features.

Questions about this item

Does the DDR4-2400 CAS-17 memory sustain full speed under continuous server load?

The module runs at 2400 MT/s with CAS-17-17-17 timings, a specification validated for sustained operation in HPE ProLiant Gen9 systems.

What thermal load does the registered 32 GB kit add when populated all day?

Registered DDR4 SmartMemory operates within standard JEDEC voltage, so the kit adds typical DIMM heat without requiring extra cooling beyond normal server airflow.

Which HPE server generations accept this 805351-B21 kit without additional parts?

The kit is qualified for HPE ProLiant Gen9, Apollo Family, Synergy and Blade Systems, unlocking SmartMemory features through the system ROM.
