Exact-Match 128 GB Kit for Supermicro H13SST-GC

This NEMIX RAM kit delivers 128 GB across eight 16 GB DDR5 5600 RDIMMs tuned to CL46 at 1.10 V. The registered ECC design with 1Rx8 organisation matches the Supermicro H13SST-GC memory controller so the full capacity is recognised at rated speed.

Who This Suits and Who Should Look Elsewhere

Server administrators populating every slot on an H13SST-GC board gain the registered buffering and error correction their platform expects. Builders needing UDIMM, SODIMM, non-ECC modules, or a different capacity per DIMM cannot use this kit.

Registered ECC RDIMM Form Factor

The 288-pin registered ECC RDIMM form factor is the single specification that determines compatibility; only motherboards wired for registered DDR5 ECC will accept these modules.

Questions about this item

Do I need a Supermicro H13SST-GC motherboard to use this 128GB kit?

Yes, this 8 x 16GB DDR5 5600 RDIMM kit is spec-matched for the Supermicro H13SST-GC and its 288-pin registered DIMM slots.

Can I mix these 1Rx8 CL46 modules with older DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds forces the memory controller to downclock to the slowest module and may break population rules; consult the board manual for approved configurations.

How do I verify the kit runs at DDR5 5600 with ECC active after install?

Enter BIOS and confirm the memory frequency reads 5600 MT/s, total capacity shows 128GB, and ECC status reports enabled or active.
