Exact-match DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 32GB of DDR5 6400 registered ECC memory in a 2x16GB configuration. It uses 1Rx8 modules at 1.1V with CL52 timing and a 288-pin RDIMM form factor. The kit is validated for the Supermicro H13SSW motherboard and uses major OEM chips from Samsung, Micron or Hynix. No heat spreaders are included.

Verify population rules and slot order

Check your motherboard manual for supported capacities per slot, approved DIMM population order and any BIOS version requirements before ordering. The board requires registered RDIMM modules, not UDIMM or SODIMM types. Confirm the system can accept 1Rx8 organisation at the rated voltage and speed. Installation steps may vary by chassis.

Replaces slower or smaller registered kits

This kit upgrades from lower-speed DDR5 registered ECC modules or smaller-capacity RDIMM sets that limit total system memory. The jump is worth it when your workload needs the full 32GB at PC5-51200 throughput with registered buffering and ECC protection. It does not suit builds that need unbuffered UDIMM memory or non-ECC operation.

Questions about this item

Does the kit include only the two 16 GB RDIMMs or are any extra cables or brackets required?

The package contains the two 16 GB DDR5 6400 RDIMMs only; no cables, brackets or other accessories are included and none are needed for installation.

Is the 32 GB (2 × 16 GB) 1Rx8 CL52 kit the right choice for a Supermicro H13SSW that needs registered ECC memory?

Yes — the 288-pin RDIMM form factor, 1.1 V operating voltage, 1Rx8 organisation and CL52 timing match the H13SSW's registered ECC requirements exactly.

Will the DDR5 6400 (PC5-51200) rating actually run at 6400 MT/s once the modules are seated in the H13SSW?

The kit is spec-matched to the board's memory controller, so with a supported CPU and current BIOS the DIMMs will initialise at their rated 6400 MT/s speed.
