Eight green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM DDR5 6400 ECC RDIMM 128GB 8x16GB CL52 1.1V Supermicro H13SSL-NT

SKU CH-1MNY-K2R0N

Eight 16 GB DDR5 ECC registered DIMMs deliver 128 GB at 6400 MT/s with CL52 latency and 1.1 V operation for the Supermicro H13SSL-NT

  • Total capacity128 GB (8 × 16 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 128 GB kit runs at full DDR5 6400 speed
  • Registered ECC design corrects single-bit errors on the fly
  • 1 V operation matches the board's memory controller spec
  • CL52 latency and 1Rx8 rank validated for Supermicro H13SSL-NT
  • 8 × 16 GB modules populate every slot at rated capacity

Exact-match server memory kit

This 128 GB kit uses eight 16 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10 V operation. Registered ECC architecture and 1Rx8 organisation match the Supermicro H13SSL-NT memory controller requirements for full-capacity recognition at rated speed.

Suited for populated H13SSL-NT builds

Administrators filling every DIMM slot on that specific motherboard gain registered buffering and on-die ECC correction for production workloads. Builders using consumer boards, UDIMM-only platforms, or systems that cannot accept registered modules should look elsewhere.

Capacity and headroom

Eight ranked modules deliver 128 GB of addressable memory with registered signalling that keeps the controller stable when all slots are occupied. Workloads exceeding this aggregate capacity or requiring higher frequencies than 6400 MT/s will need a different configuration.

Questions about this item

What motherboard must I already have for this 128GB DDR5 6400 ECC RDIMM kit to work?

The kit is validated for the Supermicro H13SSL-NT motherboard, which accepts 288-pin registered DDR5 DIMMs.

Will these eight 1Rx8 registered modules run together with any existing RDIMMs I keep in the other slots?

Population rules are board-specific; the H13SSL-NT manual defines which slots must be filled first and whether mixed ranks are allowed.

How can I confirm the kit is running at its rated 6400 MT/s with CL52 timings after installation?

Check the BIOS memory information or an OS tool such as dmidecode to verify speed, voltage at 1.10 V, and CAS latency 52.
