Twelve green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 576GB 12x48GB DDR5 6400 CL52 2Rx8 1.1V ECC RDIMM Supermicro H13SST-G

SKU CH-BR24-A65FD

12-module 576GB DDR5-6400 CL52 1.1V ECC RDIMM kit for Supermicro H13SST-G servers

  • Total capacity576 GB (12 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 576 GB total capacity from twelve 48 GB modules for maximum memory density
  • DDR5 6400 speed with CL52 latency delivers rated bandwidth for server workloads
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically

  • 1 V operating voltage and 2Rx8 rank configuration meet the board's memory-controller spec

Exact-fit server memory kit

This 576GB kit contains twelve 48GB DDR5 6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SST-G memory controller expects. It is intended for administrators who need to populate every supported slot with validated modules that run at the rated 1.1V CL52 specification.

Verified fitment and registered ECC

The modules match the 288-pin RDIMM form factor required by the H13SST-G and are not compatible with UDIMM or SODIMM sockets. Registered buffering offloads the memory controller so all twelve slots can operate at full capacity, while on-die ECC corrects single-bit errors before they affect production workloads.

Check population rules before ordering

Server memory support varies by model and BIOS revision. Consult the Supermicro H13SST-G manual for the approved DIMM population order, maximum supported capacity per slot and any required firmware updates before installing this twelve-module kit.

Questions about this item

Will the 12 RDIMM modules need any firmware updates or scheduled replacement after deployment?

The kit is an exact-match upgrade built to the Supermicro H13SST-G memory controller spec; no firmware updates are required and the modules are rated for continuous server operation.

Which limit appears first when the 12x48GB DDR5-6400 CL52 kit runs fully populated under sustained load?

The registered ECC architecture offloads the memory controller so every slot runs at the rated 6400 MT/s without throttling; the practical ceiling is the motherboard's maximum supported capacity.

What noise, heat or power impact should I expect from the 576GB DDR5-6400 1.1V ECC RDIMM kit running all day?

Operating at 1.1V with no heat spreaders, the modules add minimal thermal load and draw only standard DDR5 RDIMM power; they are silent and rely on the chassis airflow already present in the server.
