A-Tech 16GB DDR3L 1333MHz ECC LRDIMM 4Rx4 Server Memory

16GB DDR3L ECC LRDIMM for servers

This module is a 16GB DDR3L 1333MHz ECC Load Reduced DIMM built as a compatible replacement for the Samsung M386B2K70DM0-YH9. It targets server and workstation operators who need registered ECC memory to maintain data integrity under continuous operation. The low-voltage design runs at 1.35V to reduce power draw in dense memory configurations.

Load Reduced 4Rx4 architecture

The single specification that determines fit is the Load Reduced 4Rx4 organisation, which places an isolation buffer on the command and address lines so the memory controller sees only one electrical load per rank. Systems that require standard Registered DIMMs or a different rank configuration will not accept this module, so the platform memory qualification list must confirm LRDIMM 4Rx4 support before purchase.

Sustained throughput at 1.35V

Under sustained load the module operates at DDR3L 1333MHz with CL9 latency while maintaining the 1.35V supply, allowing populated channels to run cooler than equivalent 1.5V parts during long compute passes. The Samsung chipset and A-Tech validation testing target consistent bandwidth delivery rather than peak burst rates, so throughput remains stable across extended virtualization or database workloads.
