Exact-match DDR5 ECC RDIMM kit for Supermicro H13SSW

This 192GB kit contains twelve 16GB DDR5-4800 RDIMM modules rated at CL40 and 1.1V. Each module uses a 1Rx8 registered ECC design that matches the memory controller expectations of the Supermicro H13SSW motherboard. The precise rank, voltage, and timing allow the system to recognise the full capacity and run at the rated speed without manual adjustment.

Registered architecture and 288-pin form factor

Registered buffering offloads the memory controller so every slot can be fully populated at full capacity while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor is the only type the H13SSW accepts; UDIMM or SODIMM modules will not fit or function. Modules ship without heat spreaders, relying on server chassis airflow for cooling.

Verify population rules

Server memory support varies by model and BIOS revision. Consult the Supermicro H13SSW manual for approved DIMM population order, maximum supported capacity per channel, and installation steps. This kit is not suitable for platforms that require unbuffered UDIMM modules or non-ECC memory.

Questions about this item

Does DDR5 4800 CL40 limit the Supermicro H13SSW to 4800 MT/s?

The kit is rated at DDR5 4800 (PC5-38400) with CL40 latency. The Supermicro H13SSW memory controller will run these registered ECC modules at up to 4800 MT/s when populated according to the board's population rules.

Will 12 modules of 288-pin RDIMM fit the Supermicro H13SSW slots?

The kit contains twelve 288-pin DDR5 RDIMMs. The H13SSW requires registered DIMMs in its 288-pin DDR5 slots; verify the exact slot count and population order in the motherboard manual before installing all twelve modules.

What is the correct installation order for 12x16GB RDIMMs on the H13SSW?

Consult the Supermicro H13SSW manual for the approved DIMM population sequence. A common mistake is filling slots sequentially from CPU1 instead of following the board's specific channel-interleaving order, which can prevent the system from recognising the full 192 GB capacity.
