HX-MR-X32G2RS-H Cisco 32GB PC4-21300 DDR4-2666MHz ECC

HX-MR-X32G2RS-H Overview

The HX-MR-X32G2RS-H is a 32GB DDR4 memory module developed for Cisco servers, particularly those in the UCS and HyperFlex series. It operates at a speed of 2666MHz and follows the PC4-21300 standard, making it suitable for high-performance and data-intensive workloads. This memory module is a Registered DIMM (RDIMM) with ECC (Error-Correcting Code) support, which enhances data integrity and system stability—essential features for enterprise and data center environments.

The module has a dual-rank (2Rx4) configuration and uses a 288-pin form factor. It runs at a low voltage of 1.2V, helping reduce power consumption while maintaining performance. With a CAS latency of 19 (CL19), it delivers a balanced combination of speed and reliability. This RAM is typically used in Cisco UCS B200 M5, C220 M5, C240 M5, C480 M5 servers, as well as HyperFlex HX220c and HX240c M5 nodes.
