64GB DDR4 2933MHz ECC LRDIMM Module

This 64GB DDR4 2933MHz module is a single 288-pin ECC LRDIMM built for server platforms that require load-reduced memory. It runs at PC4-23400 with a CAS latency of 21 and operates at 1.2V using major OEM chips from Samsung, Micron or Hynix. The 4Rx4 rank configuration helps maximise density per slot in compatible systems.

Server Builders Needing High-Density Registered

This module suits administrators upgrading or repairing servers that specifically call for DDR4 2933MHz ECC LRDIMM. It is not for desktop PCs, workstations that require standard RDIMM or UDIMM, or any system that does not support load-reduced topology. Buyers who need non-ECC memory or faster speeds should look at something else.

4Rx4 Rank Determines Slot Population Limits

The 4Rx4 organisation is the critical specification that dictates how many modules the memory controller can address per channel. If the server documentation limits rank count per channel, this single 64GB stick may reach that limit faster than lower-rank alternatives. Verify the platform's maximum supported ranks before purchasing.

Questions about this item

Does my server motherboard need 288-pin DDR4 slots that support ECC LRDIMM modules?

Yes, this 64GB stick is a 288-pin DDR4 LRDIMM with ECC and a 4Rx4 organisation, so the board must accept load-reduced registered memory.

Can I keep my existing PC4-23400 ECC RDIMMs installed next to this LRDIMM?

No, load-reduced DIMMs and standard registered DIMMs cannot be mixed in the same server; all slots must use the same registered-buffer type.

After installation, how can I confirm the module is recognised at 2933 MHz with ECC active?

Check the BIOS memory information or run a tool such as dmidecode; it should show 64GB, 2933 MT/s, PC4-23400, CAS 21, 1.2 V and ECC enabled.
