Exact-match DDR5 kit for Supermicro H13SSH

This 128GB kit contains four 32GB DDR5 5600 RDIMMs built to the exact rank, voltage and timing the H13SSH memory controller expects. Each module is a 2Rx8 registered ECC DIMM running at 1.1V with CL46 latency. The kit is designed so the board recognises the full capacity and operates at the rated 5600 MT/s speed.

DDR5 5600 registered ECC limits

DDR5 5600 sets the maximum data rate at 5600 MT/s and the standard voltage at 1.1V for this registered ECC implementation. The registered buffer reduces electrical load on the memory controller, allowing all four slots to be populated at full capacity, while ECC corrects single-bit errors on the fly. The board's own population rules and maximum supported capacity per slot remain the governing constraints.

Four-slot installation on H13SSH

Installing the kit means seating all four 288-pin RDIMMs in the order the Supermicro H13SSH manual specifies for a four-module configuration. Common issues arise when modules are placed in the wrong slots, when the BIOS is not updated to the version that supports the full 128GB population, or when a UDIMM or SODIMM is mistakenly used instead of the required registered form factor.

Questions about this item

Should I choose the 128GB kit with four 32GB modules or a different capacity for my Supermicro H13SSH?

This exact-match kit provides 128GB total using four 32GB DDR5-5600 RDIMMs. Populate all four slots following the motherboard manual's population order to run at full rated speed and capacity.

What does DDR5-5600 CL46 actually deliver once installed in the H13SSH?

The modules operate at 5600 MT/s with CAS latency 46 at 1.1V. Registered ECC architecture lets the memory controller run every slot fully populated at that speed while correcting single-bit errors on the fly.

How does the 288-pin RDIMM interface and PC5-44800 rating limit real-world performance?

The 288-pin RDIMM form factor is required by the H13SSH; UDIMM or SODIMM will not fit. PC5-44800 confirms the 5600 MT/s data rate, so bandwidth is capped at that DDR5-5600 specification.
