NEMIX RAM
A 64 GB DDR5 ECC registered server memory kit with two 32 GB modules rated at 4800 MT/s, CL40 latency and 1.10 V, validated for the Cisco UCS X210c M7 compute node
This 64 GB kit contains two 32 GB DDR5 4800 registered ECC RDIMMs built for the Cisco UCS X210c M7 compute node. Each module runs at 1.1 V with CL40 timing and a 1Rx4 organisation. The 288-pin form factor matches the server's memory slots exactly.
The kit suits administrators expanding a UCS X210c M7 with validated DDR5 RDIMMs. It is not for systems that require unbuffered UDIMMs, non-ECC modules or a different DDR generation. Builders needing lower latency, higher frequency or a different pin count should look at other memory types.
The 288-pin registered DIMM interface is the single specification that determines fit. Only platforms wired for DDR5 RDIMM sockets can accept these modules; any other memory slot will not work.

The DDR5 4800 (PC5-38400) interface provides a data rate of 4800 MT/s with a PC5-38400 designation.
Each 32 GB module uses a standard 288-pin DDR5 RDIMM form factor with no heat spreader, so it fits any compatible Cisco UCS X210c M7 DIMM slot without extra clearance.
Power down the node, open the chassis, align each 288-pin module with the keyed slot, press firmly until the ejector tabs click, then verify in BIOS that both 32 GB modules are recognised as a 64 GB kit at 4800 MT/s.
