OWC 16GB DDR3L ECC RDIMM Kit

This OWC kit supplies 16GB of DDR3L ECC registered memory in a matched pair of 8GB modules. It is built for workstations and servers that require 240-pin DDR3L RDIMMs with error correction. Standard desktop boards cannot use this memory, and it must not be mixed with unbuffered DIMMs.

240-Pin Registered Design and 1.35V Operation

Each module uses a 240-pin RDIMM form factor with a registered buffer that reduces electrical load on the memory controller. The DDR3L rating allows operation at 1.35V, lowering power draw compared to standard DDR3. No heat spreader is fitted, so airflow in the chassis handles cooling directly.

Replaces Supermicro MEMDR380L Series Modules

This kit replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16. It suits Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH and X9DRi motherboards. Builders needing unbuffered memory or consumer desktop DIMMs should look elsewhere.

Questions about this item

What speed does the DDR3L 1600 interface actually run at?

The kit operates at DDR3L 1600 (PC3L-12800) with a CAS latency of CL11.

Will these 240-pin RDIMMs fit in a standard desktop motherboard?

No, they are registered ECC modules designed for Supermicro X9DR series server and workstation boards only.

How do I install the two 8 GB sticks correctly?

Populate matching memory channels on the X9DR board; do not mix these registered DIMMs with unbuffered memory.
