Supermicro H13SSW DDR5 ECC RDIMM kit

This 192GB kit contains six 32GB DDR5 6400 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SSW memory controller expects. It is intended for administrators who need to populate every slot with validated capacity.

DDR5 6400 registered ECC limits

Registered DDR5 at 6400 MT/s with CL52 and 1.1V lets the memory controller drive a fully populated board without signal degradation, while ECC corrects single-bit errors before they reach the operating system. The board's own population rules still dictate which slots must be filled first and the maximum capacity per channel.

288-pin RDIMM installation notes

The 288-pin RDIMM form factor keys only one way into the H13SSW slots; align the notch, press evenly until the latches click, then verify the BIOS reports all 192GB at DDR5-6400. A common issue is skipping the manual's prescribed population order, which can leave capacity unrecognised or force a lower speed.

Questions about this item

Should I choose the 192GB 6 x 32GB kit or a different capacity for the Supermicro H13SSW?

The 192GB kit provides six 32GB modules that match the board's 288-pin RDIMM slots and population rules. Consult the motherboard manual for supported capacities and approved DIMM order before deciding.

What does the DDR5 6400 speed mean once the modules are installed in the server?

The memory controller will recognise the kit at its rated 6400 MT/s (PC5-51200) with CL52 latency and 1.1V, delivering the full bandwidth the platform expects when all slots are populated.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered architecture buffers address and command signals so every slot runs fully populated at 6400 MT/s, while ECC corrects single-bit errors on the fly to prevent silent data corruption.
