256GB DDR5 4800 kit for Cisco UCS X210c M7

This 256GB kit contains eight 32GB DDR5 4800 ECC registered DIMMs built for the Cisco UCS X210c M7 compute node. Each module runs at 1.10V with CL40 latency and uses a 1Rx4 organisation on 288-pin RDIMM form factor. It targets IT teams expanding memory capacity in that specific server platform.

Thermals and power at DDR5 4800

The modules operate at the standard DDR5 4800 data rate and 1.10V without a heat spreader, relying on the server's directed airflow for cooling. Registered buffering and on-die ECC add minimal latency overhead while maintaining signal integrity across all eight slots under sustained load. Power draw scales linearly with the 256GB total capacity at the rated voltage.

What the kit contents change

The package delivers a matched set of eight 32GB DIMMs pre-validated for the Cisco UCS X210c M7, eliminating the need to source individual modules or verify rank compatibility. Major OEM Samsung, Micron or Hynix DRAM ensures consistent quality across the kit. No additional software, cables or cooling accessories are included beyond the memory modules themselves.

Questions about this item

How do I install the 8x32GB DDR5 RDIMMs in the Cisco UCS X210c M7 and what step is often missed?

Power down the node, open the chassis, align each 288-pin module with its slot, press firmly until both latches click, then verify in BIOS that all 256GB are recognised at 4800 MT/s; the step often missed is seating every module until both latches engage.

What maintenance or replacement will the 1Rx4 ECC RDIMM kit need over time?

The modules have no moving parts or heat spreaders, so routine maintenance is limited to keeping the server air filters clean; replacement is only required if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What limit appears first when the 256GB kit runs sustained workloads at CL40 1.1V?

The registered DDR5 4800 interface caps throughput at PC5-38400, so memory bandwidth saturates before the 1.1V power envelope or thermal limits become a bottleneck.
