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.

Questions about this item

How much power does the 1.5V DDR3 1600 module draw when the Supermicro 1027GR runs continuously?

The module operates at 1.5V, matching the standard DDR3 voltage for registered server memory. Actual power draw depends on the 1027GR platform workload and the number of DIMMs installed.

What must the buyer already own for this 240-pin ECC RDIMM to function?

A Supermicro SuperServer 1027GR series system with available 240-pin DDR3 registered DIMM slots. The module will not work in standard desktops or with unbuffered memory.

Can this 16GB 2Rx4 CL11 stick run alongside older DDR3 registered modules already in the 1027GR?

Yes, provided the existing modules are also DDR3 ECC registered. Mixing with unbuffered memory is not supported. The system will run all modules at the lowest common speed and latency.
