64GB DDR4 2933MHz ECC RDIMM

This 64GB DDR4 2933MHz ECC Registered RDIMM uses a 2Rx4 Hynix chipset and runs at 1.2V with CL21 latency. It is Supermicro certified as MEM-DR464L-HL02-ER29 for validated server compatibility. The 288-pin module is built for multi-socket platforms that require registered memory with error correction.

Who this suits and who it does not

Suits administrators upgrading Supermicro servers that specify PC4-23400 registered ECC modules. Unsuitable for workstations or desktops that accept only unbuffered UDIMM memory. Buyers who need lower-density sticks or faster DDR4 speeds must select different modules.

The specification that decides fit

The module is a 288-pin DDR4 RDIMM with registered ECC and 2Rx4 organisation. Your motherboard memory-qualified-vendor-list must list this exact form factor, rank and voltage for the system to post and run correctly.

Questions about this item

How can I confirm the module is running at 2933 MHz with CL21 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report DDR4 2933 (PC4-23400) at 1.2 V with a CAS latency of 21.

What ships with the module and what must be sourced separately?

The box contains one 64 GB RDIMM (HMAA8GR7AJR4N-WM); no cables, brackets or additional parts are included, so nothing extra is required for installation.

When should I choose this 64 GB 2Rx4 registered DIMM over other capacities?

Select this module when your server board supports DDR4 2933 registered ECC memory, has 288-pin slots, and you need maximum density per slot with dual-rank 2Rx4 organisation.
