Server DDR4 64GB registered module

This single 64GB DDR4-2933 registered DIMM delivers error-correcting memory for enterprise servers and workstations that require ECC protection. The 4Rx4 organisation and 1.2V operation suit high-density configurations where data integrity matters more than low latency. It is not for standard desktop or laptop platforms that accept only unbuffered modules.

288-pin keyed installation

The module fits any DDR4 RDIMM slot keyed for registered memory; the notch position prevents accidental insertion into unbuffered sockets. Ensure the motherboard supports 4Rx4 density and DDR4-2933 speeds before seating the DIMM, as some server boards limit rank count per channel. Firmware updates may be required on older platforms to recognise the full capacity.

Sustained ECC throughput

Under continuous workloads the registered buffer reduces electrical load on the memory controller, allowing stable operation at the rated 2933MT/s with CL21 timings. ECC correction runs transparently during extended compute or virtualisation tasks, maintaining data integrity without the error accumulation seen in non-ECC memory during long runs.

Questions about this item

How can I verify the 2933MHz speed and 4Rx4 rank are active after installation?

Enter the server BIOS or use a tool such as dmidecode to confirm the module reports DDR4 2933 PC4-23400, CAS 21, 1.2V and 4Rx4 organisation.

What is included in the kit and what must be sourced separately?

The kit contains one 64GB 288-pin ECC RDIMM; no cables, brackets or additional memory modules are supplied.

Which version should I choose if my server requires registered ECC memory at 2933MHz?

Select this 64GB 4Rx4 DDR4 2933MHz PC4-23400 RDIMM when your platform specifies registered ECC at that speed and rank.
