  • Total capacity32 GB
  • Rated speedDDR4 2133
  • ChipsetMajor Brand Chipset
  • CAS latencyCL15
  • Rated voltage1.2 V
  • Buffer typeLoad Reduced
  • 32 GB capacity supports large virtualisation workloads
  • DDR4-2133 speed delivers PC4-17000 bandwidth for demanding applications
  • ECC protection detects and corrects single-bit errors automatically
  • Load-reduced 4Rx4 design lowers electrical load on the memory controller
  • 20 V operation reduces power draw in dense server configurations

HP-compatible 32GB DDR4-2133 LRDIMM

This 32GB DDR4-2133 ECC LRDIMM is built for HP servers that require load-reduced memory. It runs at 1.20V with CL15 latency and uses a 4Rx4 rank configuration. The module suits administrators extending the life of existing infrastructure.

288-pin installation with matched modules

The 288-pin DDR4 form factor fits standard server DIMM slots. All orders ship with identically matched modules to prevent mismatched memory issues. Compatibility is validated against the HP 726722-B21 part number before shipping.

DDR4-2133 bandwidth ceiling

The PC4-17000 rating caps throughput at the DDR4-2133 data rate. Load-reduced buffering helps signal integrity on dense 4Rx4 configurations but does not raise the interface speed. Systems limited to lower memory clocks will not exceed this module's rated frequency.

Questions about this item

How do I confirm the 32GB DDR4-2133 ECC LRDIMM is detected at the correct speed and rank after installation?

Enter the server BIOS or UEFI and verify the module shows 32GB capacity, 2133 MT/s speed, CL15 latency, 1.20V voltage, 4Rx4 rank and ECC enabled.

What is included with the 726722-B21-BN module and what must be sourced separately?

The box contains one 288-pin DDR4 LRDIMM; no additional cables, brackets or software are required, but a compatible HP server with free DDR4 slots is needed.

Which capacity and rank should I choose for a server that requires 32GB 4Rx4 load-reduced modules?

Select this 32GB 4Rx4 PC4-17000 DDR4-2133 LRDIMM; it matches the HP 726722-B21 specification exactly.
