Cisco UCS DDR5 4800 ECC RDIMM

This 32GB registered DDR5 module is built for Cisco UCS servers that require ECC RDIMM memory. It targets IT teams upgrading compatible Cisco platforms with validated enterprise memory.

Check Cisco UCS qualification

Confirm the exact Cisco UCS model supports DDR5 4800 registered ECC DIMMs and verify the qualified vendor list includes this part number. Review the system manual for maximum capacity per channel and required slot filling order before ordering.

288-pin RDIMM with Samsung Micron Hynix chips

The module uses major OEM DRAM chips without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, and the 1.1V operating voltage matches standard DDR5 server specifications for daily operation.

Questions about this item

Does the 32GB DDR5 4800 module ship alone or with extra hardware?

The package contains one 32GB 288-pin DDR5 RDIMM rated at 4800MT/s CL40 1.1V. No brackets, cables or additional parts are included.

When should I pick the 1Rx4 registered ECC version over other capacities?

Choose this 32GB 1Rx4 registered ECC stick when your Cisco UCS server requires DDR5 4800 registered memory with error correction and a single rank per module.

What does the 4800MT/s CL40 rating deliver in a live Cisco UCS system?

The module runs at the standard DDR5 4800 speed with 40-cycle latency, providing the bandwidth and error-corrected stability the platform expects for registered server workloads.
