Targeted Server Upgrade

This 32GB kit delivers two 16GB DDR4-3200 ECC registered DIMMs built for Cisco UCS B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 systems. It is intended for administrators who need validated memory to expand capacity in those specific platforms.

Build Integration

The modules use the 288-pin RDIMM form factor at 1.2V and require slots that accept registered ECC memory; they will not work in standard desktop boards or alongside unbuffered or load-reduced DIMMs. Populating both sticks frees the remaining slots for future matched pairs while keeping the memory subsystem uniform.

Sustained Operation

Rated at CL22 and PC4-25600, the kit maintains JEDEC-compliant timing under continuous server workloads such as virtualization or database tasks. The registered buffer reduces electrical load on the memory controller, helping stability during extended duty cycles without relying on a heat spreader for thermal management.

Perguntas sobre este artigo

Will the DDR4-3200 CL22 timing limit throughput when the Cisco UCS server runs sustained workloads?

The kit operates at DDR4-3200 (PC4-25600) with CL22 latency; sustained throughput is determined by the memory controller in the Cisco UCS platform.

How much heat or power do the two 16 GB registered ECC modules add during all-day operation?

Each module runs at 1.2 V without a heat spreader; total power draw and thermal output depend on the server's memory-subsystem design.

Which existing Cisco UCS part numbers must this kit replace to work correctly?

The kit replaces Cisco part numbers UCSMRX16G1RW and UCSXMRX16G1RW in the B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 servers.
