  • ECC registered design protects data integrity in servers
  • 16 GB kit (2 × 8 GB) expands workstation capacity
  • DDR3L 1600 CL11 at 1.35 V lowers power draw
  • 240-pin RDIMM fits Supermicro 7037A, 7047AX, 7047GR
  • JEDEC and RoHS compliant for reliable upgrades

Target system and purpose

This kit provides 16 GB of DDR3L ECC registered memory in two 8 GB modules for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems. It is built for workstations and servers that require error-correcting registered DIMMs and will not operate in standard desktop computers.

Compatibility checks before ordering

Verify that your motherboard accepts 240-pin DDR3L registered ECC DIMMs at 1.35 V and that the CPU and chipset support 1600 MHz operation with CL11 timing. Do not mix these registered modules with unbuffered memory and confirm the system BIOS recognises 1Rx4 rank configuration.

What the kit changes

The matched pair enables dual-channel bandwidth for supported platforms while ECC and registered buffering improve data integrity under sustained loads. Replacing older Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16 extends usable life without requiring a full platform refresh.

Questions about this item

What is included in the kit and is anything else needed for installation?

The kit contains two 8 GB DDR3L 1600 CL11 ECC registered RDIMMs for a total of 16 GB. No extra parts are required; the modules install directly into the 240-pin slots of a compatible Supermicro SuperWorkstation.

Which capacity or version should I choose for a Supermicro 7037A, 7047AX or 7047GR workstation?

This 16 GB kit (2 × 8 GB) matches the Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16 listed for those models.

What does the 1600 MHz rating mean once the memory is running in my workstation?

The modules operate at DDR3L 1600 (PC3L-12800) with CL11 latency at 1.35 V, delivering the rated bandwidth and error-correcting registered performance for the supported Supermicro SuperWorkstation series.
