Capacity and configuration

This NEMIX RAM kit delivers 192GB of DDR5 server memory in a matched set of six 32GB RDIMM modules. Registered ECC design and 1.1V operation target enterprise platforms that require error correction and signal integrity at scale. The modules run at 4800MHz with CL40 latency and use a 1Rx4 organisation across 288 pins.

Suited for Supermicro DDR5 servers

The kit is validated for Supermicro UP SuperServer SYS-111C-NR, SYS-521C-NR and X13SEDW-F motherboards. Builders using other server boards, workstations without registered DIMM support, or systems limited to fewer than six slots should verify compatibility before purchase. Non-ECC consumer platforms cannot use these registered modules.

Registered ECC RDIMM form factor

The decisive specification is the registered ECC RDIMM interface; only motherboards wired for DDR5 registered DIMMs with ECC enabled will post with this memory. Unbuffered, non-ECC or earlier DDR generations are physically and electrically incompatible.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the SuperMicro SYS-111C-NR server?

Yes, the kit is validated for SuperMicro UP SuperServer SYS-111C-NR, SYS-521C-NR and X13SEDW-F motherboards using the 288-pin DDR5 RDIMM form factor.

Which slots should I populate first when installing the six 32 GB modules?

Follow the motherboard manual's population order — typically fill the farthest slot from the CPU on each channel first, then work inward across all six DIMM sockets.

Will the Samsung, Micron or Hynix chips on these modules require any firmware updates later?

No firmware updates are needed for the DRAM chips; the modules run at 1.1 V with CL40 timings and are covered by a lifetime replacement warranty if any module fails.
