Server-grade ECC RDIMM for Cisco UCS C4200

This 64GB DDR4 module is an ECC registered DIMM built for the Cisco UCS C4200 server platform. It operates at 3200 MT/s with a CAS latency of 22 and runs at 1.2V. The 2Rx4 dual-rank organisation fits the 288-pin RDIMM slot and replaces Cisco part numbers UCSMRX64G2RW, UCS-MR-X64G2RW-M and UCSXMRX64G2RW. It is not compatible with standard desktop computers or unbuffered and load-reduced memory types.

Thermals, noise and power draw in normal use

The module has no heat spreader and relies on the server chassis airflow for cooling. Power consumption stays at the standard 1.2V DDR4 level during typical operation. As a passive component it generates no acoustic noise of its own. ECC circuitry adds a small overhead that is accounted for in the JEDEC-compliant power envelope.

Behaviour under sustained load

Registered buffering helps maintain signal integrity when all ranks are active for extended periods. The single 64GB stick populates one slot, leaving room for further expansion within the C4200 memory architecture. JEDEC compliance ensures timing parameters remain stable at 3200 MT/s during continuous workloads. Mixing with unbuffered or load-reduced DIMMs is not supported and would prevent the system from booting.

Perguntas sobre este artigo

How do I install this 64GB DDR4 3200 RDIMM in a Cisco UCS C4200, and what step is most often missed?

Power down the server, open the chassis, align the 288-pin module with the slot key, press firmly until both latches click, then verify in BIOS that all 64GB are detected at 3200 MT/s; the step most often missed is confirming the BIOS registers the full capacity and speed before closing the case.

What maintenance or replacement will this 2Rx4 ECC registered module need over its service life?

No routine maintenance is required; the module has no heat spreader, so keep server airflow paths clean, and replace only if ECC correctable error counts rise or the system logs uncorrectable errors indicating a failing DRAM chip.

What limit appears first when this 1.2V CL22 RDIMM runs sustained workloads in a Cisco UCS C4200?

The CAS latency of 22 cycles at 3200 MT/s sets the baseline response time; under sustained load the memory controller’s thermal throttling or the platform’s maximum DIMM-per-channel limit will cap throughput before the module’s own rating is exceeded.
