OWC 2R9D42R816GB 16GB DDR4 2933MHz CL21 ECC RDIMM memory upgrade

Server ECC RDIMM for Supermicro X11

This OWC DDR4 module delivers 16 GB of registered ECC memory at 2933 MHz with CL21 latency. It is built for Supermicro motherboards X11SRi-IF, X11SRL-F, X11SRM-F and X11SRM-VF. The part replaces Supermicro MEMDR416LCL01ER29, MEMDR416LCL03ER29, MEM-DR416LD-ER29, MEMDR416LHL04ER29 and MEMDR416LHL05ER29. It suits administrators expanding capacity in compatible servers or workstations.

288-pin registered DIMM at 1.2 V

The stick uses a standard 288-pin DDR4 form factor without a heat spreader. Registered buffering and ECC provide the error correction and signal stability required by multi-socket server platforms. It operates at 1.2 V and is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz bus speeds. Mixing with unbuffered memory is not supported.

Upgrade from lower-capacity or slower DDR4 RDIMMs

Installing this module adds 16 GB per slot and raises the memory clock to 2933 MHz where the platform allows. The jump is worthwhile when the workload needs more ECC-protected capacity or when replacing failed sticks with a validated alternative. It will not fit standard desktop boards that require unbuffered non-ECC memory.
