Exact-match DDR5-6400 RDIMM kit

This NEMIX RAM kit delivers 64 GB in two 32 GB registered ECC DDR5 modules rated at 6400 MT/s with CL52 latency and 1.1 V operation. The 288-pin RDIMM form factor and 2Rx8 organisation match the Supermicro H14SST-GE motherboard requirements for full-capacity recognition at rated speed.

Verify motherboard population rules

Consult your Supermicro H14SST-GE manual for approved DIMM population order, maximum supported capacity per slot, and installation sequence before ordering. Registered ECC RDIMMs are required; UDIMM or SODIMM modules will not function in this platform.

Suits servers needing registered ECC capacity

This kit fits administrators expanding a validated Supermicro H14SST-GE configuration with matched registered ECC memory. Builders requiring unbuffered UDIMMs, non-ECC modules, SODIMM form factor, or a different speed grade should select an alternative product.

Questions about this item

Does the 64GB kit ship as two 32GB modules or do I need to buy a second stick?

The kit includes two 32GB RDIMMs for a total of 64GB, so nothing else is required to reach that capacity.

Why is this kit specified as 2Rx8 rather than 1Rx8 or 2Rx4?

The Supermicro H14SST-GE memory controller expects 2Rx8 organisation; using a different rank layout can prevent the system from recognising the full 64GB or running at DDR5-6400.

Will the CL52 timing hold at the rated 6400 MT/s once the modules are installed in the H14SST-GE?

Yes, the kit is spec-matched to the board's memory-population rules, so the controller trains at DDR5-6400 with CL52 at 1.1V without manual tuning.
