A-Tech 32GB DDR3L 1333 ECC LRDIMM 4Rx4 for Samsung M386B4G70BM0-YH9 M386B4G70DM0-YH9 Server Memory

32 GB DDR3L ECC LRDIMM for servers

This 32 GB DDR3L module runs at 1333 MHz with CL9 latency and 1.35 V operation. It uses a 4Rx4 Load Reduced DIMM design with ECC for error correction in server and workstation platforms. The 240-pin form factor matches the Samsung M386B4G70BM0-YH9 and M386B4G70DM0-YH9 part numbers it replaces.

Capacity and headroom

A single 32 GB stick adds substantial memory to compatible DDR3L systems, supporting larger virtualisation hosts, database buffers and multi-user workloads. The Load Reduced architecture reduces electrical load on the memory bus, allowing higher total capacity per channel than standard registered DIMMs. Systems limited to DDR3L 1333 will not run this module at higher speeds, and boards without LRDIMM support cannot use it at all.

Upgrade context

This module replaces the listed Samsung 32 GB DDR3L 1333 ECC LRDIMM parts directly, providing a drop-in alternative for maintenance or capacity expansion. The jump is worth it when a server requires ECC LRDIMM modules at this density and speed, and the platform’s memory controller and BIOS support 4Rx4 organisation. Buyers needing non-ECC, unbuffered, standard registered or higher-speed DDR3 memory cannot use this module.
