Server ECC Registered Memory

This OWC 8GB DDR3L 1600 module is an ECC registered RDIMM built for Supermicro SuperServer 1027 and 2027 series systems. It operates at 1.35V with CL11 latency and a 1Rx4 rank configuration. The 240-pin form factor fits server and workstation boards that require registered memory. It will not work in standard desktop computers or alongside unbuffered modules.

Thermals and Power Draw

The module runs at the low-voltage DDR3L standard of 1.35V, reducing power consumption compared with 1.5V DDR3. No heat spreader is fitted, so airflow across the DIMM slots handles cooling. Registered buffering adds minimal latency while improving signal integrity under sustained server workloads. Acoustic impact is negligible in typical chassis designs.

Compatibility Constraint

This part is validated only for the listed Supermicro SuperServer 1027B, 1027GR, 1027R, 1027TR and 2027GR series. It replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16. Buyers with other platforms, desktop boards, or a need for unbuffered ECC memory must choose a different module.

Questions about this item

How do I install the 240-pin DDR3L RDIMM in a Supermicro SuperServer 1027R and what step is often missed?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both retention clips click, then confirm the BIOS registers the 8GB capacity at 1600MHz.

What maintenance or replacement will this ECC registered module need over time?

No routine maintenance is required; the module either continues operating or develops correctable errors that ECC logs, at which point you replace the individual 8GB DIMM.

What limit appears first when the 1Rx4 1.35V DIMM runs sustained workloads in a 2027GR?

The registered buffer adds one cycle of latency, so memory-controller throughput saturates before the DRAM cells reach thermal or voltage limits.
