MICRON MTA72ASS8G72LZ-2G3B2 64GB DDR4 2400 RDIMM
The Micron MTA72ASS8G72LZ-2G3B2 is a 64GB DDR4-2400 load-reduced DIMM (LRDIMM) built for enterprise servers, high-density memory deployments, and virtualization platforms. It suits system integrators and data center buyers who need to maximize per-channel capacity on supported Intel or AMD server platforms. Note that LRDIMMs use a memory buffer to reduce electrical load, and mixing with RDIMMs on the same channel is not supported — always verify your platform’s qualified vendor list (QVL) before ordering.

Good to know
- As an LRDIMM, this module cannot be mixed with RDIMMs or UDIMMs on the same memory channel — populate all channels with the same module type, and follow your motherboard manual’s population order for multi-rank modules.
- Within Micron’s DDR4 server lineup, the quad-rank 4Rx4 configuration with load reduction makes this a high-density option for platforms that cap RDIMM capacity, typically serving as bulk memory in virtualization hosts rather than low-latency cache tiers.
- Before purchasing, confirm the exact part number (2G3B2 speed bin) against your server’s QVL, since BIOS and memory-controller support for LRDIMMs varies by platform generation.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
