Server Memory Kit

This NEMIX RAM kit delivers 128GB of DDR5 ECC registered memory in two 64GB modules. It is built for the Cisco UCS X210c M7 compute node and suits administrators who need validated capacity for virtualisation or database workloads. The registered design adds signal integrity for multi-DIMM server boards.

Thermals and Power

Modules run at 1.10V with a CL40 latency profile and no heat spreader installed. The low-voltage DDR5 architecture reduces power draw compared with previous server memory generations. Passive cooling relies on chassis airflow across the bare PCB, so adequate case ventilation is required for sustained loads.

Build and Connectors

Each 288-pin RDIMM uses a 2Rx4 organisation sourced from major OEM Samsung, Micron or Hynix die. The kit targets the Cisco UCS X210c M7 memory slots directly and is not intended for desktop or unbuffered platforms. Buyers who need non-ECC memory or consumer motherboard compatibility should look elsewhere.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules into the Cisco UCS X210c M7 compute node and which step is commonly missed?

Power down the node, open the chassis, align the notch on each 64 GB module with the slot key, press firmly until both side clips click, then verify in BIOS that all 128 GB are detected at 4800 MT/s; the step often missed is seating both clips fully so the register engages.

What maintenance or replacement will the 2Rx4 ECC registered kit need during its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement only occurs if a module fails, which is covered by the manufacturer’s lifetime replacement warranty.

What limit appears first when the 1.1 V CL40 kit runs sustained workloads in the Cisco UCS X210c M7?

The primary limit is the DDR5 4800 MT/s data rate and CL40 latency ceiling; thermals are secondary because the registered design and 1.1 V operation keep temperatures within spec without active cooling.
