SuperMicro 64GB DDR4 2666MHz ECC LRDIMM — MEM-DR464LE-LR26

The SuperMicro MEM-DR464LE-LR26 is a 64GB DDR4 2666MHz (PC4-21300) ECC Load-Reduced DIMM (LRDIMM) in 288-pin form factor, operating at 1.2V with CL19 latency and quad-rank configuration. LRDIMM technology uses a memory buffer to reduce the electrical load on the memory controller — enabling higher DIMM counts per channel and maximum memory capacity in enterprise servers. ECC protection ensures data integrity for mission-critical workloads.

Frequently Asked Questions

What is the difference between LRDIMM and RDIMM?

LRDIMM uses a memory buffer to reduce electrical load, enabling more DIMMs per channel and higher total capacity. RDIMM uses a register for signal buffering but has higher electrical load per DIMM. LRDIMMs allow maximum memory density in servers.

Can I mix LRDIMM and RDIMM in the same server?

No — LRDIMM and RDIMM cannot be mixed in the same server. All DIMMs must be the same type.

What server platforms support LRDIMM?

Intel Xeon Scalable and AMD EPYC platforms with LRDIMM support are compatible. Verify with your specific server vendor's memory compatibility list.
