OWC 16GB DDR3 1600 CL11 2Rx4 1.5V ECC Registered RDIMM server RAM

Server Memory Upgrade

This OWC module adds 16GB of DDR3 ECC registered memory to compatible workstations, servers, NAS systems and routers. It matches Supermicro part numbers including MEM-DR316L-HL01-ER16 and MEM-DR316L-SL01-ER16 for direct replacement. The 240-pin RDIMM is designed for 24/7 operation in multi-socket platforms that require registered DIMMs. It will not work in standard desktop computers or alongside unbuffered modules.

Thermals and Power

Operating at 1.5V, the module draws standard DDR3 power without a heat spreader. Passive cooling relies on chassis airflow across the bare PCB. Registered buffering reduces electrical load on the memory controller, helping keep system power draw predictable under sustained workloads. No active cooling or additional voltage is required for rated 1600MHz CL11 operation.

Build Integration

The 240-pin form factor fits DDR3 RDIMM slots in qualified server and workstation boards. ECC and registered signalling must be supported by the platform; mixing with unbuffered DIMMs is not supported. Each module presents a 2Rx4 organisation, allowing high-density population where the memory controller permits. JEDEC and RoHS compliance ensures warranty-safe integration into existing OEM infrastructure.
