Server memory kit for Supermicro H13SSF

This NEMIX RAM kit delivers 192GB across four 48GB DDR5 RDIMM modules. It is built for administrators who need registered ECC memory that matches the H13SSF motherboard's exact requirements. The modules run at 5600 speed with CL46 latency at 1.1V. Buyers who need a different capacity, unbuffered DIMMs, or a non-ECC configuration should look elsewhere.

Registered ECC RDIMM with 2Rx8 organization

The single specification that determines fit is the registered ECC RDIMM format with 2Rx8 rank structure. The H13SSF memory controller expects this exact combination of buffering, error correction, and rank geometry. A UDIMM, SODIMM, or different rank configuration will not be recognized or will prevent the system from posting. The 288-pin DDR5 interface and 1.1V operating voltage are also mandatory for this platform.

Straightforward installation with population rules

Installation follows standard DIMM insertion into the 288-pin slots, but the H13SSF manual defines a specific population order that must be followed for all four modules to operate at 5600. The most common issue is populating slots in the wrong sequence, which causes the system to run at reduced speed or detect less than 192GB. No heat spreaders are present, so airflow clearance is not a concern. Consult the motherboard manual before installing.

Questions about this item

Will the 5600 MT/s speed run at full rate when all four slots of the Supermicro H13SSF are populated?

The kit is spec-matched to the board's memory-population rules so the registered ECC RDIMMs are recognised at the full 5600 MT/s rating across all four slots.

Does the 288-pin RDIMM form factor match the Supermicro H13SSF's DDR5 slots, and is it different from UDIMM or SODIMM?

Yes, these are 288-pin DDR5 RDIMMs — the registered form factor the H13SSF requires — and they are not interchangeable with UDIMM or SODIMM modules.

What physical clearance do the modules need since they have no heat spreader?

Without a heat spreader the modules use the standard low-profile RDIMM height, so they fit in the H13SSF's DIMM slots even with close-pitch heatsinks or airflow ducts.
