Capacity & form factor

This NEMIX RAM kit delivers 768 GB of DDR5 memory in six 128 GB RDIMM modules. Each stick is a 288-pin registered DIMM rated at 4800 MT/s with CL40 latency and 1.10 V operation. The 4Rx4 organisation and on-die ECC suit enterprise workloads that require maximum density per channel.

Who this suits

IT teams upgrading Supermicro CloudDC SuperServer models SYS-621C-TN12R, SYS-611C-TN4R or SYS-121C-TN2R will find a validated, plug-compatible population. Buyers needing unbuffered UDIMMs, lower voltages, or consumer desktop form factors cannot use this registered server memory.

Deciding specification

The registered RDIMM interface with ECC and 4Rx4 ranking is the single attribute that determines compatibility; only motherboards designed for registered DDR5 ECC modules at 4800 MT/s can accept this kit.

Questions sur cet article

How much power does each 128 GB DDR5 4800 CL40 RDIMM draw at 1.1 V under sustained load?

Each module operates at 1.1 V; total kit capacity is 768 GB across six 128 GB RDIMMs.

Which Supermicro platforms must the buyer already own for this 6×128 GB kit to be compatible?

Compatible systems listed are SuperMicro CloudDC SuperServer SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R.

Will these 288-pin DDR5 ECC RDIMMs work alongside existing DDR5 RDIMMs of different capacity or rank in the same server?

The kit uses 4Rx4 organisation at DDR5 4800 CL40; mixing ranks or capacities depends on the motherboard memory population rules.
