64 GB DDR5 4800 ECC RDIMM

This 64 GB DDR5 4800 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1.10 V with a CAS latency of CL40 and uses a 2Rx4 organisation. The module fits standard 288-pin DDR5 slots and is validated for Micron-compatible platforms.

Suited for registered-memory platforms only

This module suits administrators upgrading or populating DDR5 RDIMM slots in compatible server or workstation boards. It is not for systems that accept only unbuffered UDIMMs, nor for laptops or compact PCs that require SO-DIMM form factors. Buyers needing non-ECC memory or a different rank configuration should look elsewhere.

2Rx4 rank and CL40 latency decide fit

The single specification that determines compatibility is the 2Rx4 registered ECC layout combined with CL40 timing at DDR5 4800. The memory controller must support registered ECC DIMMs with this rank structure and latency; otherwise the module will not initialise or will run at reduced stability.

Questions about this item

How can I verify the module is running at 4800 MT/s with CL40 after installation?

Check the memory speed and latency in your server BIOS or a hardware monitoring utility; they should show 4800 MT/s and CL40 at 1.10 V.

What comes in the package and do I need any extra parts?

One 64 GB 288-pin DDR5 RDIMM is included; no cables or brackets are required, just an available RDIMM slot on a compatible server board.

Should I choose the 2Rx4 64 GB version or a different capacity for my server?

The 2Rx4 64 GB module suits platforms that support 2-rank x4 registered DIMMs; match the rank and capacity to your motherboard's qualified-vendor list.
