Exact-match 384 GB DDR5 kit for Supermicro H13SSW

This 12-module kit delivers 384 GB of DDR5 4800 registered ECC memory. Each 32 GB module runs at 1.1 V with CL40 timing in a 2Rx8 configuration. The kit is built to the precise rank, voltage and timing the Supermicro H13SSW memory controller expects for full-capacity recognition at rated speed.

Registered DDR5 limits and population rules

Registered DDR5 offloads the memory controller so all twelve slots can run fully populated at 4800 MT/s while ECC corrects single-bit errors on the fly. The 288-pin RDIMM form factor is mandatory for this platform; UDIMM or SODIMM modules will not fit or function. Motherboard population rules dictate the exact slot order, so full capacity depends on following the documented sequence.

Verify your H13SSW configuration before ordering

Consult the Supermicro H13SSW manual for supported capacities, approved DIMM population order and installation steps. BIOS version can affect memory recognition, so confirm the board firmware matches the vendor’s validated list. This kit is not suitable for systems that require UDIMM, SODIMM or non-ECC DDR5 memory.

Questions about this item

Should I choose the 12x32GB kit or a different capacity for the Supermicro H13SSW?

The 12x32GB kit delivers the full 384GB capacity this motherboard supports when all twelve DDR5 slots are populated with registered ECC modules.

What does DDR5-4800 mean for actual throughput on the H13SSW?

Each module runs at 4800 MT/s, providing PC5-38400 bandwidth per channel; twelve populated channels give the maximum aggregate throughput the platform allows.

How does the 288-pin RDIMM interface affect installation on this board?

The 288-pin registered DIMM form factor matches the H13SSW slots exactly; the registered buffer lets all twelve slots operate at full speed without signal degradation.
