OWC 16GB DDR3 ECC Registered RDIMM

This 16GB DDR3 1600 module is built for workstations and servers that require ECC registered memory. It fits Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. The single DIMM delivers 16GB capacity at CL11 latency and 1.5V operation. It is not compatible with standard desktop computers or unbuffered memory configurations.

Capacity and headroom for server workloads

The 16GB capacity provides headroom for virtualization, database caching and multi-user file services on supported platforms. Registered signalling and ECC correction maintain data integrity under sustained load. The module runs out of headroom when applications demand more than 16GB per slot or require higher memory bandwidth than DDR3 1600 can supply.

Replaces specific Supermicro part numbers

This module replaces Supermicro part numbers MEMDR316LHL01ER16, MEMDR316LSL01ER16, MEMDR316LSL03ER16 and MEMDR316LSV01ER16. The upgrade is worth it when expanding memory in the listed X9 series boards or when substituting failed modules with a JEDEC-compliant alternative. It does not serve systems that require unbuffered DIMMs or a different DDR generation.

Questions about this item

Will this 16GB DDR3 1600 CL11 2Rx4 1.5V registered ECC module work alongside my existing unbuffered DDR3 DIMMs?

No, registered ECC memory cannot be mixed with unbuffered modules; the system requires all slots to use registered DIMMs.

How can I verify the 16GB DDR3 1600 CL11 1.5V module is running correctly after installation?

Check the BIOS or UEFI memory information screen; it should show 16GB at 1600 MHz, CL11, 1.5 V, and ECC registered status.

Does the 16GB DDR3 1600 PC3-12800 CL11 240-pin 1.5V ECC RDIMM ship alone or with extra parts?

The box contains only the single 16GB memory module; no cables, brackets or additional components are included.
