128GB DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 memory as four 32GB registered DIMMs. Each module runs at 4800MT/s with CL40 latency at 1.1V. The registered ECC design is built for server platforms that require error correction and signal buffering.

Suited for Supermicro H13SST-G upgrades

The kit matches the Supermicro H13SST-G motherboard's 288-pin RDIMM requirement and 2Rx8 rank structure. Builders needing UDIMM, SODIMM or non-ECC memory should look elsewhere. Systems limited to lower speeds or different pin counts cannot use these modules.

Registered ECC DDR5 at 4800MT/s

The registered architecture with on-die ECC allows full-capacity population while correcting single-bit errors. This specification determines whether the memory controller will initialise the kit at its rated 4800MT/s speed and 128GB total capacity.

Highlights

  • Full 128 GB capacity in a matched 4 × 32 GB kit
  • DDR5 4800 speed with CL40 timing runs at rated performance
  • Registered ECC architecture corrects single-bit errors on the fly
  • 10 V low voltage reduces power draw per module
  • Verified fit for Supermicro H13SST-G motherboard with 288-pin RDIMM slots

Questions about this item

Will these 288-pin DDR5 RDIMM modules fit the Supermicro H13SST-G motherboard?

Yes, the 288-pin Registered RDIMM form factor matches the slots on the Supermicro H13SST-G motherboard; UDIMM or SODIMM modules will not fit.

What is the correct installation order for the four 32GB modules on the Supermicro H13SST-G?

Follow the motherboard manual for the approved DIMM population sequence; the kit includes four 32GB 2Rx8 modules that must be installed in the specified slot order for full capacity recognition.

Do these registered ECC DDR5 modules need any firmware updates or periodic maintenance?

No firmware updates are required for the memory itself; ECC corrects single-bit errors automatically, and the modules run at 1.1V with CL40 timing for the life of the server.
