16 GB DDR4 3200 ECC RDIMM for Cisco UCS

This 16 GB DDR4 3200 ECC Registered RDIMM is built for Cisco UCS B200 M6, C125 M5, C220 M6, C240 M6 and C245 M6 servers. It delivers 288-pin PC4-25600 performance at CL22 latency and 1.2 V. The module uses a 1Rx4 organisation and has no heat spreader.

ECC Registered design and single-rank layout

Error-correcting code protects data integrity in multi-socket workloads. The registered buffer reduces electrical load on the memory controller, allowing higher densities per channel. The 1Rx4 configuration keeps signal integrity tight without mixing with unbuffered or load-reduced DIMMs.

Suited for Cisco UCS server refreshes.

IT teams extending the life of listed Cisco UCS platforms or building new nodes with matching DIMMs will benefit. Buyers who need unbuffered memory for workstations, consumer motherboards or mixed-rank populations should look at something else.

Perguntas sobre este artigo

Will the 16GB DDR4 3200 ECC RDIMM need a firmware update or replacement after years in a Cisco UCS C240 M6?

No firmware updates are required for the memory itself; the module either works or fails, so plan replacement only if a stick reports correctable errors or the system logs uncorrectable ECC events.

What limit appears first when the 1Rx4 1.2V registered DIMM runs sustained workloads on a Cisco UCS B200 M6?

The memory controller’s maximum supported capacity per channel is reached before thermal or power limits on the module itself.

How much heat and fan noise does the 288-pin 16GB DDR4 3200 CL22 module add during all-day operation in a Cisco UCS C220 M6?

Without a heat spreader the DIMM relies on chassis airflow; power draw stays at the standard 1.2V level so extra heat and fan noise are minimal in a properly cooled server.
