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.

Questions about this item

What does the 1333 MHz DDR3L speed mean for real-world server performance?

The 1333 MHz DDR3L rating sets the maximum data rate the memory controller can use. Actual throughput depends on the platform's memory-channel configuration and workload.

How does the DDR3L 1.35 V interface limit power and compatibility?

DDR3L modules operate at 1.35 V, reducing power draw compared to standard DDR3. They fit DDR3 slots that support low-voltage operation; the platform must enable 1.35 V for correct function.

Will the 240-pin LRDIMM form factor fit my server's memory slots?

This module uses a 240-pin DIMM edge connector. It requires motherboard slots wired for DDR3 Load-Reduced DIMMs; standard UDIMM or RDIMM-only slots will not accept it.
