Axiom 862976-B21-AX 16GB DDR4-2400 CL17 288-pin UDIMM monitor accessory

SKU CH-42DN-PZ4ZZ

16 GB DDR4-2400 CL17 288-pin unbuffered DIMM for HPE systems

  • 16 GB DDR4-2400 capacity supports demanding workloads
  • CL17 latency keeps response times low
  • 288-pin UDIMM design fits standard desktop slots
  • Unbuffered ECC architecture protects data integrity

Axiom 16GB DDR4-2400 ECC UDIMM

This 16GB DDR4 module operates at 2400 MT/s with CL17 latency and ECC error correction. The unbuffered 288-pin UDIMM form factor fits compatible HPE systems using part number 862976-B21. It provides registered reliability for workloads that demand data integrity.

Capacity and headroom

The single 16GB stick adds substantial memory for virtualisation, databases or large datasets. ECC overhead protects against silent corruption during long compute runs. Systems limited to lower densities or non-ECC memory cannot use this module. Buyers needing higher speeds or larger kits must look elsewhere.

Highlights

  • 16 GB DDR4-2400 capacity supports demanding workloads
  • CL17 latency keeps response times low
  • 288-pin UDIMM design fits standard desktop slots

Questions about this item

Will the 16GB DDR4-2400 UDIMM work alongside my existing DDR4 modules?

The 288-pin DDR4 module runs at 2400 MT/s with CL17 timing; when mixed with other DDR4 UDIMMs the system will operate at the speed and latency of the slowest installed module.

How can I confirm the 16GB DDR4 module is detected correctly after installation?

Check the system BIOS or UEFI memory information screen — it should show 16 GB at 2400 MT/s with CL17 timings for the new 288-pin UDIMM.
