A-Tech 128GB DDR4 2666MHz ECC LRDIMM Micron MTA144ASQ16G72LSZ-2S6G1QG Server Memory

128GB DDR4 2666MHz ECC LRDIMM

This single 128GB module provides high-capacity DDR4 memory for servers and workstations that require error-correcting code and load-reduced DIMM technology. It targets administrators upgrading compatible Micron-based platforms where maximum density per slot is a priority. The registered design helps maintain signal integrity on heavily populated memory buses. Systems needing non-ECC or standard unbuffered DIMMs cannot use this module.

128GB capacity with 2666MHz speed

The module delivers 128GB of addressable memory at 2666MHz (PC4-21300) with a CAS latency of 19. Eight logical ranks (2S4Rx4) implemented through 3DS/TSV stacking allow this density within a standard 288-pin form factor. Workloads such as large in-memory databases, virtualization hosts, and high-thread-count compute nodes benefit from the expanded headroom. Applications that exceed 128GB per channel or require faster clock rates will hit the module's frequency and density ceiling.

1.20V operation for thermal efficiency

Operating at the standard DDR4 voltage of 1.20V, the LRDIMM architecture reduces electrical loading on the memory bus compared to conventional registered DIMMs of similar rank count. Lower loading translates to reduced power draw per gigabyte and less heat generated under sustained server workloads. The cooler operation helps maintain stable frequencies in dense chassis configurations where airflow per module is limited. No active cooling or specialised airflow beyond standard server guidelines is required.
