Server-grade DDR3L ECC RDIMM kit

This OWC kit supplies 16 GB of DDR3L registered ECC memory as two 8 GB modules. It is built for Supermicro SuperServer platforms including the 8047R, 8048B, F617R2, F617R3 and F627G2 series. Workstations or servers that require registered DIMMs with error correction are the intended audience. Standard desktop boards that accept only unbuffered memory cannot use this kit.

Registered ECC with 1Rx4 organisation

The decisive specification is the registered ECC design combined with a single-rank 1Rx4 layout at 1.35 V. This matches the Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16. Systems that need unbuffered DIMMs or a different rank configuration will not accept these modules.

Steady 1600 MHz throughput under load

Rated at DDR3L 1600 (PC3L-12800) with CL11 latency, the modules maintain their rated speed during sustained server workloads. The registered buffer reduces electrical load on the memory controller, helping stability in multi-DIMM configurations over long periods. No heat spreader is fitted, so adequate chassis airflow is required for continuous operation.

Questions about this item

What does the 1600 MHz speed mean once the kit is installed in a Supermicro server?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 latency, delivering the rated throughput when the server's memory controller operates at that frequency.

How does the DDR3L 240-pin registered ECC interface limit what the kit can do?

The registered ECC design requires a server or workstation chipset that supports registered DIMMs; it will not work in standard desktop boards and cannot be mixed with unbuffered memory.

What physical space and slot layout does the 240-pin RDIMM kit need?

Each 8 GB module is a 240-pin DDR3L RDIMM without a heat spreader, so it fits standard DDR3 DIMM slots in the listed Supermicro SuperServer chassis.
