64GB DDR4 2666MHz LRDIMM for Servers

This 64GB module uses DDR4 2666MHz memory in a 288-pin LRDIMM form factor. It is built for server platforms that require registered load-reduced DIMMs with ECC. The single-module design adds capacity without occupying additional slots.

Supermicro Certified with Samsung 4Rx4 Chipset

The module carries Supermicro certification for part MEM-DR464LE-LR26 and uses Samsung M386A8K40CM2-CTD components. It operates at 1.2V with CL19 latency and a 4Rx4 quad-rank organisation. ECC load-reduced buffering helps maintain signal integrity on densely populated memory channels.

Suits Supermicro Systems Needing 64GB LRDIMMs

This part fits administrators expanding Supermicro servers that specify DDR4 2666 LRDIMM memory. Builders using consumer motherboards, standard UDIMMs or RDIMMs, or platforms limited to lower capacities should select a different module type.

Questions about this item

How much usable memory does the 64 GB module provide in a real server?

The module delivers the full 64 GB of addressable memory to the operating system; ECC and load-reduced operation do not reduce capacity.

What does the PC4-21300 label mean for data-rate limits?

PC4-21300 identifies the module as DDR4 2666; the memory controller will run it at up to 2666 MT/s and cannot exceed that speed.

Will this 288-pin LRDIMM fit in a standard DDR4 server DIMM slot?

Yes, the 288-pin LRDIMM form factor matches the DDR4 server DIMM socket; verify your platform supports quad-rank load-reduced modules before installing.
