32 GB DDR4 2666 ECC RDIMM for servers

This registered ECC module adds 32 GB of DDR4 2666 memory to compatible Supermicro platforms. The dual-rank 2Rx4 organisation suits workloads that benefit from higher density per DIMM slot. Micron chips and Supermicro certification indicate validation for qualified server boards.

Registered 288-pin form factor with 1.20 V operation

The RDIMM register buffers address and command signals to reduce electrical load on the memory controller. Standard DDR4 voltage keeps power draw in line with platform expectations. A 288-pin edge connector fits server DIMM sockets that accept registered modules.

CL19 latency at 2666 MHz with ECC protection

Error-correcting code detects and corrects single-bit errors to maintain data integrity in continuous operation. CAS latency of 19 cycles at the rated frequency delivers predictable access timing. Registered buffering and ECC together support stable throughput under sustained server loads.
