64GB DDR4 ECC LRDIMM for servers

This 64GB DDR4 2933MHz module uses a 288-pin LRDIMM form factor with ECC and load-reduced buffering. It runs at 1.20V with CL21 latency and a 4Rx4 rank configuration. The part number is ML23400-944K1 and it is built with major OEM chips from Samsung, Micron or Hynix.

Replaces lower-capacity or non-ECC DDR4 DIMMs

Upgrading from standard unbuffered or registered DIMMs to this load-reduced design allows higher density per slot without increasing electrical load on the memory controller. The jump is worth it when a server board supports LRDIMM and needs maximum capacity per channel for virtualization or large datasets.

Suits IT teams expanding Hynix-compatible servers

This module targets administrators adding memory to qualified Hynix platforms that accept DDR4 2933MHz ECC LRDIMMs. Builders needing unbuffered UDIMMs, RDIMMs instead of LRDIMMs, or speeds other than 2933MHz should look at something else.

Questions about this item

Will the 288-pin DDR4 LRDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 LRDIMM form factor, so it fits any server or workstation slot designed for DDR4 load-reduced DIMMs.

What is the correct way to seat this 4Rx4 ECC LRDIMM during installation?

Align the notch on the module with the slot key, press down firmly until both side clips click into place, and verify the system recognises the full 64GB capacity at 2933 MT/s.

Does the 1.2 V CL21 module require any firmware updates or periodic maintenance?

No firmware updates are needed for the memory itself; keep the server's air filters clean so the modules stay within their 1.2 V operating envelope.
