64GB DDR4 LRDIMM for Supermicro Servers

This A-Tech module delivers 64GB of DDR4 2400 memory in a single 288-pin LRDIMM. It is built with Hynix chips and carries Supermicro certification for MEM-DR464L-HL01-LR24. The quad-rank 4Rx4 design targets servers that need high density per slot. ECC load-reduced operation supports data integrity in demanding workloads.

DDR4 2400 Speed and Load-Reduced Limits

The module runs at DDR4 2400 (PC4-19200) with CL17 latency at 1.20V. Load-reduced buffering reduces electrical load on the memory bus, allowing more modules per channel than standard RDIMMs. Maximum capacity and population rules depend on the specific server platform and CPU memory controller. Mixing LRDIMMs with other DIMM types is not supported.

4Rx4 Quad Rank Determines Compatibility

The 4Rx4 organisation is the key specification that decides whether this module works in a given system. Only platforms qualified for quad-rank LRDIMMs at DDR4 2400 can use it. Buyers who need single or dual-rank modules, or a different rank architecture, must select a different part. Always verify the server memory QVL before ordering.

Questions about this item

Should I choose the 64GB DDR4 2400 LRDIMM or a different capacity for my server?

This module provides 64GB in a single 288-pin LRDIMM using a 4Rx4 quad-rank layout; add multiple identical sticks to reach your platform's maximum supported memory.

What does the DDR4 2400 speed rating mean for real-world throughput in my machine?

The memory operates at 2400MHz with CL17 timing at 1.20V; actual data rates depend on your CPU's memory controller and the number of populated slots.

How does the LRDIMM ECC Load Reduced interface affect compatibility and performance limits?

The Load Reduced design reduces electrical load on the memory bus, allowing higher densities like this 64GB stick while delivering ECC error correction for data integrity.
