Supermicro Certified 64GB LRDIMM

This 64GB DDR4 2666MHz ECC Load Reduced DIMM is built for Supermicro server platforms that require high-density registered memory. The module uses Samsung chips in a 4Rx4 quad-rank layout and runs at the standard 1.20V DDR4 voltage. It targets administrators expanding memory capacity in compatible 288-pin slots.

Suits high-capacity server upgrades.

The quad-rank LRDIMM form factor and ECC Load Reduced design suit Supermicro systems validated for the MEM-DR464L-SL03-LR26 part number. Builders using consumer desktop motherboards, workstations without LRDIMM support, or platforms limited to RDIMM or UDIMM modules cannot use this memory.

Deciding spec: 4Rx4 LRDIMM at DDR4 2666

The single specification that decides fit is the 4Rx4 Load Reduced DIMM organisation combined with DDR4 2666 (PC4-21300) speed and 288-pin interface. Only systems whose qualified-vendor list includes this exact rank, voltage, and form factor will accept the module.

Questions about this item

Will this 4Rx4 LRDIMM run with my existing 2Rx4 RDIMMs in the same Supermicro server?

Mixing 4Rx4 Load Reduced DIMMs with 2Rx4 Registered DIMMs is not supported; populate all channels with identical LRDIMMs for stable operation.

How can I confirm the module is running at DDR4 2666 CL19 after installation?

Check the BIOS memory information or a tool such as CPU-Z — it should report 2666 MT/s, CAS 19, 1.20 V and ECC Load Reduced.

Does the package include only the 64 GB module or any extra parts?

The box contains a single 64 GB DDR4 2666 MHz 4Rx4 LRDIMM; no cables, brackets or additional hardware are supplied.
