Samsung 64 GB LR-DIMM for data-intensive servers

This 64 GB DDR4-2933 Load Reduced DIMM uses a 4Rx4 organisation and ECC to deliver high capacity per slot. It operates at 1.20 V on a 288-pin interface and is validated for stability in demanding server and workstation environments.

Ideal for dense memory configurations in cloud

Suits administrators who need maximum rank density without mixing memory types. Not for systems that only accept RDIMM, UDIMM or ECC UDIMM, or for any platform that does not explicitly support LR-DIMM.

Single module provides 64 GB at 2933 MT/s

Comfortably handles large virtualisation hosts, in-memory databases and analytics workloads that benefit from high per-slot capacity. Headroom ends when the memory controller reaches its maximum supported rank count or total system capacity limit.

Questions about this item

Does my server motherboard need 288-pin DDR4 slots that specifically support Load Reduced DIMMs for this module to work?

Yes, this module requires a 288-pin DDR4 slot on a motherboard that explicitly supports LR-DIMM technology; it will not function in slots limited to RDIMM or UDIMM.

Can I keep my existing RDIMM modules installed while adding this 64 GB 4Rx4 LR-DIMM?

No, LR-DIMMs cannot be mixed with RDIMMs, ECC UDIMMs or standard UDIMMs; all slots must be populated with matching LR-DIMM modules.

How do I verify the module is running at its rated 2933 MT/s speed after installation?

Enter the server BIOS or use a system-information tool such as CPU-Z to confirm the memory frequency reads 2933 MT/s and that ECC and Load Reduced modes are reported active.
