288GB DDR5 ECC RDIMM kit

This 288GB kit contains six 48GB DDR5-5600 registered ECC RDIMMs built for the Supermicro H13SST-GC motherboard. Each module runs at 1.1V with CL46 latency and a 2Rx8 organization. The registered design allows every slot to be populated while keeping the memory controller stable.

DDR5-5600 registered ECC limits

The DDR5-5600 (PC5-44800) interface sets the maximum data rate and timing envelope the board can negotiate. Registered buffering reduces electrical load on the controller but adds one cycle of latency. ECC corrects single-bit errors but cannot fix multi-bit failures, and the 2Rx8 rank structure limits maximum density per channel.

Upgrade from smaller DDR5 RDIMM sets

This kit replaces partial or lower-capacity DDR5 RDIMM populations when the workload demands full 288GB capacity at the board's rated speed. The jump is worth it when virtualization, database or compute tasks exceed the current memory ceiling and the motherboard manual confirms six-DIMM support at DDR5-5600.

Questions about this item

Should I choose the 288GB kit or a smaller capacity for my Supermicro H13SST-GC?

The 288GB kit provides six 48GB modules that fully populate the board for maximum capacity. Choose a smaller kit only if your workload does not need the full 288GB or if you plan to leave slots open for future expansion.

What does the DDR5-5600 rating mean for real-world server performance?

DDR5-5600 delivers a peak transfer rate of PC5-44800, giving each 48GB module high bandwidth for memory-intensive workloads. The CL46 latency and 1.1V operation are tuned for stability when all six slots are populated.

How does the 288-pin RDIMM interface affect compatibility and speed limits?

The 288-pin RDIMM form factor is required by the Supermicro H13SST-GC and will not fit UDIMM or SODIMM slots. Registered buffering lets the memory controller run all six modules at the rated 5600 speed without signal degradation.
