OWC 32GB (2x16GB) DDR4 2400 CL17 288-pin ECC Registered RDIMM 1Rx4 1.2V memory upgrade

Server memory kit

This 32 GB kit contains two 16 GB DDR4 2400 CL17 ECC registered RDIMMs built for Cisco UCS B260 M4 E7 v4 and B460 M4 E7 v4 servers. The modules run at 1.2 V and use a 1Rx4 organisation to provide error correction and signal buffering for multi-socket workloads. They replace Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG. Desktop or consumer platforms cannot use registered ECC memory.

Thermals and power

Operating at the standard 1.2 V DDR4 voltage keeps power draw low for dense server configurations. No heat spreader is fitted, so airflow through the chassis manages module temperatures directly. The registered design reduces electrical load on the memory controller, helping maintain stable operation under sustained throughput.

What the kit changes

Adding 32 GB of registered ECC capacity extends the usable life of the supported Cisco UCS platforms or reduces cost when populating new build slots. JEDEC and RoHS compliance ensures the modules meet industry specifications for server deployment. The kit is not compatible with unbuffered or load-reduced ECC memory types.
