OWC 16GB DDR3 1600 CL11 2Rx4 240-pin 1.5V ECC Registered RDIMM 1027GR

Server ECC RDIMM

This 16GB DDR3 1600 module is a registered ECC RDIMM built for the Supermicro SuperServer 1027GR series. It operates at 1.5V with CL11 latency and a 2Rx4 rank configuration. The 240-pin form factor fits server and workstation boards that require registered memory. It replaces Supermicro part numbers MEMDR316LHL01ER16, MEMDR316LSL01ER16, MEMDR316LSL03ER16 and MEMDR316LSV01ER16.

Sustained load stability

Registered buffering and ECC correction keep data integrity intact during continuous multi-threaded workloads. The single 16GB stick adds capacity without increasing electrical load per channel. JEDEC and RoHS compliance ensures consistent timing at the rated 1600 speed. Systems that run virtualisation, databases or long render jobs benefit from the error detection built into every cycle.

Upgrade path

This module suits administrators extending the life of a 1027GR platform or building a replacement server on a budget. It is not compatible with standard desktop boards or unbuffered DIMM slots. Buyers who need consumer DDR3, non-ECC memory or higher frequencies should look elsewhere. Mixing with unbuffered modules is not supported.
