Server memory kit for Supermicro H13SSL-N

This 1.5 TB kit contains twelve 128 GB DDR5 RDIMM modules built for the Supermicro H13SSL-N motherboard. Registered ECC architecture keeps every slot stable when fully populated. The kit targets administrators who need maximum registered capacity on this specific platform.

Registered ECC with 2Rx4 organisation

Each module is a 288-pin DDR5 RDIMM rated at 6400 MT/s (PC5-51200) with CL52 latency and 1.1 V operation. The 2Rx4 rank structure matches the memory controller expectations for full-speed recognition. Buyers who need unbuffered UDIMMs or a different rank layout cannot use this kit.

Thermals and power in normal use

Modules run at 1.1 V without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained workloads. Power draw scales with all twelve slots populated at rated frequency.

Questions about this item

Will the 6400MHz rating run at full speed on the Supermicro H13SSL-N, or does the board limit it?

The kit is spec-matched to the H13SSL-N memory controller, so the DDR5-6400 modules are recognized at their rated speed and the full 1.5TB capacity when populated per the board's rules.

What does the 288-pin RDIMM form factor mean for installation on this motherboard?

The H13SSL-N requires 288-pin Registered DIMMs; these modules match that exact form factor and will not fit UDIMM or SODIMM slots.

How much clearance do the 128GB modules need above the DIMM slots?

The modules have no heat spreader, keeping the profile low for tight server chassis clearance around the 288-pin sockets.
