NEMIX RAM 256GB (4x64GB) DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM Supermicro H13SVW-NT memory upgrade

Exact-Match Server Upgrade

This 256GB kit contains four 64GB DDR5 RDIMM modules built for the Supermicro H13SVW-NT motherboard. It delivers registered ECC memory at 6400MHz with CL52 latency and 1.10V operation. The 2Rx4 rank structure matches the board's memory controller requirements for full-capacity recognition. System integrators upgrading this specific platform receive the precise specification the firmware expects.

Registered DIMM Population Rules

The motherboard accepts only 288-pin registered DDR5 RDIMMs; unbuffered UDIMMs or SODIMMs will not function. Every slot must follow the manual's approved population order to initialise at the rated 6400MHz speed. Mixing ranks or voltages prevents the memory controller from training correctly. Buyers who cannot confirm their board's exact DIMM sequence should verify the documentation before installation.

2Rx4 Rank Determines Compatibility

The dual-rank 2Rx4 organisation is the single specification that decides whether this kit works in the target system. A different rank count changes the electrical loading on each channel and will cause POST failures or reduced capacity. Only modules presenting 2Rx4 to the memory controller satisfy the Supermicro H13SVW-NT population rules. Systems requiring single-rank or quad-rank DIMMs cannot use this kit.
