64GB DDR4 3200 ECC RDIMM module

This 64GB DDR4 3200 ECC RDIMM module targets IT professionals who manage HPE servers and workstations. The single stick delivers 64GB of registered memory with error correction for mission-critical workloads. It operates at 1.2V with a CAS latency of 22 cycles.

Replaces lower-capacity or non-ECC sticks

The module upgrades systems that currently run smaller registered DIMMs or lack error correction entirely. The jump is worth it when workloads demand maximum density per slot and data integrity under continuous operation. Compatibility is validated for HPE part number P56431-B21.

Sustained load behaviour with major OEM chips

Built with Samsung, Micron or Hynix components, the 2Rx4 registered design maintains stability during extended stress testing. Error-correcting code detects and corrects single-bit errors without halting the system. The 1.2V operation keeps thermal output predictable during long-running compute tasks.

Highlights

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 RDIMM form factor matches standard registered DIMM slots used in compatible HPE servers.

What is the correct way to seat the module so the ECC function works?

Align the notch with the slot key, press firmly until both side clips click, and verify the system reports 64GB at 3200MHz with ECC active.

Will the Samsung, Micron or Hynix chips need replacement under normal server load?

The modules are stress-tested under load and covered by a lifetime replacement warranty, so no chip replacement is expected in normal operation.
