Server-grade DDR5 RDIMM

This 64GB registered DIMM uses DDR5 technology at 6400MHz with CL52 latency and 1.1V operation. It targets administrators upgrading SuperMicro MEM-DR564L-SL02-ER64 compatible platforms that require ECC registered memory.

DDR5 6400 registered constraints

The module follows the PC5-51200 standard with 2Rx4 organisation and 288-pin form factor. Registered buffering adds one cycle of command latency, and ECC function requires platform support; consumer desktop chipsets cannot use this memory.

64GB single-module capacity

One stick delivers 64GB, allowing dense population of available DIMM slots for large memory footprints. Workloads exceeding this per-slot density or needing faster than 6400MHz transfer rates will require different modules.

Questions about this item

Should I pick the 64GB 2Rx4 module or a different capacity for my server?

This module provides 64GB in a single 2Rx4 registered DIMM; choose it when your platform needs one 64GB stick at 6400MHz with ECC.

What does the 6400MHz rating deliver once the DIMM is installed in a server?

The module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, giving the rated throughput and timing the motherboard negotiates.

How does the 288-pin registered ECC interface limit what I can use this memory in?

The 288-pin RDIMM form factor with registered ECC only fits server boards wired for DDR5 registered memory; it will not work in desktop or unbuffered slots.
