OWC 2R9D42R816GB 16GB DDR4 2933 ECC RDIMM memory upgrade

Targeted Server Upgrade

This 16GB DDR4 2933MHz ECC Registered DIMM is built for Supermicro X11 series motherboards including the X11DPT-L, X11DPT-PS, X11DPU, X11DPX-T and X11DSC+. It suits administrators expanding memory in compatible workstations, servers or NAS systems that require registered error-correcting modules. It will not work in standard desktop computers or alongside unbuffered memory.

Thermals and Power

Operating at 1.2V, the module runs at standard DDR4 voltage without a heat spreader, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity at 2933MHz speeds with CL21 latency. Backward compatibility with 2133MHz, 2400MHz and 2666MHz systems allows flexible deployment across mixed-speed configurations.

Build and Installation

The 288-pin RDIMM uses a 2Rx8 rank organisation and conforms to JEDEC and RoHS standards for reliable insertion into server DIMM slots. OWC tests every module in-house before shipment. Buyers needing unbuffered ECC or non-ECC memory for consumer platforms cannot use this product.
