Exact-match DDR5-6400 RDIMM kit

This NEMIX RAM kit delivers 128 GB as two 64 GB DDR5-6400 modules built to the Supermicro H13SSL-NT memory controller specification. Each module is a 288-pin Registered ECC RDIMM running at 1.1 V with CL52 latency and a 2Rx4 rank structure. The parts use major OEM DRAM from Samsung, Micron or Hynix and ship without heat spreaders.

Fits H13SSL-NT DIMM slots directly

The 288-pin Registered form factor matches the board’s required RDIMM slots — not UDIMM or SODIMM — so the kit installs in the approved population order without adapters. Registered buffering offloads the memory controller, allowing every populated slot to run at the rated 6400 MT/s speed while ECC corrects single-bit errors on the fly. Consult the motherboard manual for supported capacities and exact slot sequence before installation.

Suits servers needing validated 128 GB capacity

This kit targets administrators who need a tested, spec-matched 128 GB upgrade for the H13SSL-NT platform with lifetime replacement coverage. Builders requiring UDIMM or SODIMM form factors, non-ECC modules, different voltages, or capacities beyond what the board’s population rules allow should look at other memory options.

Highlights

Questions about this item

Will the 2Rx4 registered ECC RDIMM run at the rated 6400 speed when all 13 slots of the H13SSL-NT are populated?

The kit is spec‑matched to the Supermicro H13SSL-NT memory‑population rules, so it will be recognised at full 128 GB capacity and operate at DDR5 6400 (PC5 51200) with CL52 timing at 1.1 V.

Does the lack of a heat spreader raise thermals or fan noise during continuous 24/7 server workloads?

These modules run at the standard DDR5 1.1 V without a heat spreader; registered ECC RDIMMs are designed for dense server chassis where airflow handles cooling, so no extra noise or thermal throttle is expected.

What motherboard slot type and CPU memory controller are required for this 288‑pin DDR5 RDIMM kit to function?

The kit needs a motherboard with 288‑pin DDR5 RDIMM slots and a CPU that provides a native DDR5 memory controller — the Supermicro H13SSL-NT provides exactly that.
