64GB LRDIMM for Supermicro servers

This 64GB DDR4 2666MHz module is built for Supermicro platforms that require ECC load-reduced memory. It targets administrators expanding capacity in qualified systems where registered DIMMs are mandatory.

Quad-rank 4Rx4 design fits dense configurations

The 288-pin LRDIMM form factor installs in standard DDR4 server slots and operates at 1.20V with CL19 latency. Quad-rank organisation allows larger per-slot capacity, freeing additional DIMM slots for future expansion.

Supermicro certification and Micron chipset

Certified as MEM-DR464L-CL02-LR26 with Micron MTA72ASS8G72LZ-2G6D2 components, the module passes vendor qualification testing. A-Tech adds lifetime warranty coverage and US-based technical support for the product lifecycle.

Questions about this item

Will the CL19 latency become the bottleneck during sustained heavy workloads?

CL19 is the rated CAS latency at DDR4 2666; it remains constant under load and is the primary timing limit for this module.

How much heat and power does a 64GB 1.20V LRDIMM generate when running continuously?

The module operates at standard 1.20V DDR4 voltage; LRDIMM buffering reduces electrical load on the bus, keeping power draw and thermals within normal server DIMM limits.

What motherboard features must my system already have to use this 288-pin ECC LRDIMM?

Your motherboard must provide DDR4 288-pin slots that support ECC Load Reduced DIMMs and quad-rank 4Rx4 modules at 2666MHz.
