64GB DDR4 2933 ECC RDIMM Server Module

This is a single 64GB DDR4 2933MHz registered ECC DIMM built for server and workstation platforms. It runs at 1.2V with CL21 latency and uses a 2Rx4 organisation on a 288-pin interface. The module is validated as a direct replacement for the listed HP part numbers.

Buyers needing registered ECC memory

This module suits administrators upgrading or repairing HP systems that require DDR4 2933 registered ECC DIMMs. It will not work in platforms that only accept unbuffered non-ECC memory or that are limited to lower speeds or smaller capacities per slot.

Registered ECC with 2Rx4 organisation

The registered ECC design with 2Rx4 rank structure is the decisive specification; the system memory controller must support registered DIMMs and this rank configuration for the module to function correctly.

Questions about this item

What motherboard slot does the 288-pin DDR4 RDIMM require?

The module fits a standard DDR4 288-pin DIMM slot on a server or workstation motherboard that supports registered ECC memory.

Will the CL21 2933 MHz module downclock automatically if installed with slower DDR4 RDIMMs?

Yes, the memory will negotiate the lowest common speed and latency across all populated slots, so it runs at the slower modules' rated frequency and timings.

How can I confirm the 64 GB ECC RDIMM is recognised and error-correcting after installation?

Check the system BIOS or UEFI memory information screen; it should show 64 GB at 2933 MHz with ECC status enabled for the new module.
