Cisco UCS server memory upgrade

This 32GB DDR4 3200 CL22 ECC registered RDIMM is built for Cisco UCS B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 systems. It targets administrators who need to expand capacity in those specific rack and blade servers with a single 32GB module.

Registered ECC DDR4 constraints

The module runs at 1.2V with a 2Rx4 organisation and CL22 latency on a 288-pin interface. It cannot be mixed with unbuffered or load-reduced DIMMs, and it will not function in standard desktop platforms that lack registered ECC support.

Pre-installation checklist

Verify that every populated slot uses the same capacity, speed and manufacturer to avoid timing conflicts. Confirm the server model matches the listed Cisco part numbers 15-107238-01, UCSMRX32G2RW or UCSXMRX32G2RW before ordering.

Questions about this item

Should I pick a different capacity or speed for my Cisco UCS server?

This module is a single 32 GB DDR4 3200 CL22 2Rx4 registered DIMM; choose it when you need one 32 GB stick at that speed and rank.

What does the 3200 MT/s rating deliver in my Cisco UCS B200 M6 or C240 M6?

The module runs at DDR4 3200 (PC4 25600) with CL22 latency, providing the rated throughput and timing the platform expects for registered ECC memory.

Is the 288 pin DDR4 interface compatible with my Cisco UCS C220 M6 and does ECC registration affect maximum capacity?

Yes, it uses the standard 288 pin DDR4 registered ECC form factor required by the listed Cisco UCS servers; the registered design allows the platform to scale to its supported maximum memory.
