64 GB DDR5 ECC RDIMM for Supermicro

This 64 GB DDR5 module runs at 6400 MHz with CL52 latency and 1.1 V operation. It uses a 2Rx4 registered ECC design on a 288-pin form factor. The part is validated for Supermicro Hyper SuperServer SYS-122HA-TN-LCC systems.

Suited for registered ECC server upgrades.

This module fits servers that require registered ECC DDR5 memory. It will not work in consumer desktop boards that lack ECC and registered support. Buyers needing unbuffered non-ECC memory for standard PCs should look elsewhere.

6400 MHz CL52 DDR5 speed grade

The memory operates at 6400 MHz with a CAS latency of 52. This speed grade determines compatibility with the server memory controller and must match the platform specification.

Questions about this item

How do I confirm the module is running at 6400 MHz with CL52 latency after installation?

Enter the server BIOS or use a tool such as CPU-Z to verify the memory frequency reads 6400 MHz and the CAS latency shows 52.

What is included in the package and do I need any extra parts for a Supermicro SYS-122HA-TN-LCC?

The box contains one 64 GB 288-pin DDR5 ECC RDIMM; no additional components are required for that Supermicro model.

Should I choose a different capacity or rank if my board has limited DIMM slots?

This single 64 GB 2Rx4 module delivers the full capacity in one slot, leaving remaining slots free for future expansion.
