Exact DDR5-6400 RDIMM for Supermicro H13SSW

This NEMIX RAM module delivers 32GB of DDR5 6400 memory in a registered ECC RDIMM form factor built for the Supermicro H13SSW motherboard. It targets server administrators who need a capacity-matched upgrade that the board recognises at full speed without manual tuning.

Registered 2Rx8 CL52 at 1.1 V

The single specification that decides fit is the registered 2Rx8 organisation running at CL52 and 1.1 V on a 288-pin DDR5 interface. Only modules with this exact rank, voltage and timing will initialise at the rated PC5-51200 data rate on the H13SSW memory controller.

Seat firmly in the prescribed slot order

Installation requires pressing the 288-pin RDIMM into the motherboard slots following the population sequence in the Supermicro manual until both retention clips click. The most common issue is mixing registered and unregistered DIMMs or skipping the mandated slot order, which prevents the system from posting.

Questions about this item

Will the 6400 MT/s speed run at that rate once installed in my Supermicro H13SSW?

The module is spec-matched to the board's memory controller, so it is recognised at full capacity and operates at its rated 6400 MT/s without manual tuning.

What does the 288-pin RDIMM form factor mean for compatibility with my H13SSW?

The H13SSW requires a 288-pin Registered DIMM; this module matches that exact keying and will not fit UDIMM or SODIMM slots.

Does this 32 GB stick need a heatsink or extra clearance to fit in the H13SSW?

No heat spreader is included, so the module uses the standard low-profile RDIMM height and fits within the server's normal DIMM spacing.
