64GB DDR4 2400 LRDIMM

This 64GB DDR4 2400 LRDIMM delivers 2400 MHz speed with CL17 latency at 1.20V. It uses a 288-pin form factor with 4Rx4 organisation and load-reduced buffering. ECC capability protects data integrity in critical workloads. The module is validated for Supermicro MEM-DR464L-HL01-LR24 compatibility.

Suitable for high-density server upgrades

Designed for systems that accept DDR4 LRDIMM modules with 4Rx4 rank structure and 1.20V operation. Buyers needing standard RDIMM or unbuffered DIMM formats should look elsewhere. Platforms limited to lower capacities or different voltage requirements cannot use this module.

DDR4 2400 4Rx4 LRDIMM ECC

The defining specification is the 4Rx4 load-reduced ECC configuration at DDR4 2400. This rank and buffering combination determines whether the memory will initialise on a given motherboard. Verify that your platform supports 4Rx4 LRDIMM population rules before purchasing.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM, and what step is often missed?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both latches click, then verify the system recognises all 64GB at DDR4 2400; the step often missed is populating slots in the exact sequence the server manual specifies for 4Rx4 modules.

What maintenance or replacement will this 64GB module need later?

No scheduled maintenance is required; if a memory error occurs the module itself is replaced, and the Supermicro MEM-DR464L-HL01-LR24 certification means a direct drop-in spare of the same 64GB 4Rx4 CL17 1.20V spec restores operation.

What limit appears first under sustained load with this 4Rx4 2400 MHz kit?

The quad-rank 4Rx4 organisation increases electrical loading, so the memory controller typically hits its maximum supported rank-per-channel limit before the 2400 MT/s speed or 1.20V voltage becomes a bottleneck.
