OWC 16GB DDR3L 1600 CL11 ECC Registered RDIMM 2Rx4 1.35V memory upgrade

Server ECC memory for Supermicro X9DR series

This 16 GB DDR3L registered DIMM is built for workstations and servers using Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH or X9DRi motherboards. It provides ECC error correction and registered buffering required by those platforms. The module is not compatible with standard desktop computers.

Verify registered DDR3L support before ordering

Confirm the motherboard accepts 240-pin DDR3L registered ECC memory at 1.35 V and CL11 latency. The module cannot be mixed with unbuffered DIMMs, so all slots must use registered modules. Check the system manual for maximum capacity per channel and total supported memory.

Low-voltage operation reduces heat and power draw

Running at 1.35 V, the DDR3L module draws less power and generates less heat than standard 1.5 V DDR3 in typical server workloads. No heat spreader is fitted, so airflow across the DIMM slots handles cooling. Registered buffering adds minimal latency while maintaining signal integrity at full 1600 MHz speed.
