64GB DDR4 ECC Registered RDIMM

This 64GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is a 288-pin ECC Registered RDIMM organised as 2Rx4, built to JEDEC specifications. The module carries no heat spreader. It is designed for servers and workstations that require registered error-correcting memory.

Suited for registered ECC platforms only

This memory fits systems that accept DDR4 ECC Registered RDIMMs and will not work in standard desktop computers. It cannot be mixed with unbuffered modules. Buyers who need non-ECC or unbuffered memory for consumer motherboards should look elsewhere.

64GB single-module capacity

A single module provides 64GB of registered ECC capacity for multi-socket servers or high-density workstations. It handles large virtualisation workloads, database buffers and memory-intensive compute tasks. Systems limited to lower per-slot densities or unbuffered memory cannot use this module.

Perguntas sobre este artigo

Does my motherboard need to support registered ECC DDR4 memory for this 288‑pin 64GB module to work?

Yes, this is a registered ECC RDIMM that requires a server or workstation platform with DDR4 registered memory support; it will not function in standard desktop boards that only accept unbuffered DIMMs.

Can I mix this 2Rx4 CL22 registered DIMM with the unbuffered DDR4 sticks already in my system?

No, registered and unbuffered DDR4 cannot be mixed; all installed modules must be registered ECC RDIMMs of the same specification for the system to operate correctly.

How can I verify the module is running at DDR4 3200 with ECC active after installation?

Check the BIOS or UEFI memory information screen — it should report 3200 MT/s, CL22 timings, 1.2 V and ECC enabled for each installed 64GB DIMM.
