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

Compatible Supermicro Server Memory

This 16GB DDR4 2933MHz ECC Registered RDIMM is built for Supermicro motherboards X11DSN-TS, X11OPi-CPU, X11QPH+, X11QPL and X11SPA-T. It targets administrators upgrading workstations, servers or NAS systems that require registered memory with error correction. The module operates at 1.2V with CL21 latency and a 2Rx8 rank configuration. It will not work in standard desktop computers or alongside unbuffered DIMMs.

JEDEC Compliant Registered Design

The registered buffer reduces electrical load on the memory controller, allowing larger total capacities in multi-slot server boards. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. JEDEC and RoHS compliance ensures a warranty-safe upgrade path for the listed Supermicro platforms. No heat spreader is fitted, so airflow in dense chassis remains unimpeded.

16GB Capacity With Backward Speed Support

Each DIMM provides 16GB of capacity at the rated 2933MHz speed, and will also run at 2666MHz, 2400MHz or 2133MHz when installed in slower systems. This headroom suits virtualisation hosts, database nodes or file servers that benefit from maximum registered DIMM populations. Builders needing unbuffered memory, desktop compatibility or speeds above 2933MHz must choose a different module type.
