64GB ECC Registered RDIMM for servers

This 64GB DDR4 2933MHz module is built for workstations, servers and NAS systems that require registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs. The part matches the specifications of Kingston KSM29RD4/64HAR.

Capacity and speed headroom

The single stick provides 64GB at PC4-23400 with CL21 latency and 1.2V operation. It runs at 2933MHz and steps down to 2666MHz, 2400MHz or 2133MHz when the platform demands it. Systems needing more than 64GB per slot or higher frequencies will require different modules.

288-pin registered build

The 288-pin RDIMM uses a 2Rx4 organisation without a heat spreader, keeping the profile low for dense server chassis. Registered signalling reduces electrical load on the memory controller, supporting stability in multi-DIMM configurations. JEDEC and RoHS compliance ensure a warranty-safe upgrade path.

Questions sur cet article

Will this 288-pin DDR4 2933MHz registered ECC module run in a server that currently uses 2400MHz DIMMs?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz systems, so it will operate at the speed supported by your existing platform.

How can I verify the 64GB module is detected and running with ECC active after installation?

Check the system BIOS or UEFI memory information screen; it should show 64GB capacity, 2933MHz speed, registered ECC status and 1.2V operation.

Does the single 64GB RDIMM ship alone or with any extra components such as a heat spreader?

The module is supplied as a single 288-pin DDR4 RDIMM without a heat spreader; no additional parts are included.
