Exact DDR5-5600 RDIMM kit for Supermicro

This 576 GB kit contains twelve 48 GB DDR5-5600 RDIMM modules rated CL46 at 1.1 V. It is built for servers that require registered ECC memory and will only work in systems that accept 288-pin RDIMMs populated in the exact order the motherboard specifies.

DDR5 RDIMM population rules limit installation order

Registered DDR5 memory must be installed in the sequence the board's memory controller expects. Filling every slot with 2Rx8 modules works only when the platform supports that rank count per channel; otherwise the system will not post or will run at reduced capacity.

Verify board manual for supported capacity

Before ordering, check the Supermicro H14DSG-O-CPU manual for maximum memory per socket, approved DIMM population tables, and any BIOS version requirements. The kit will not function in boards that require UDIMMs, SODIMMs, or a different rank configuration.

Questions about this item

Should I choose the 12-module 576GB kit or a smaller capacity for my Supermicro H14DSG-O-CPU?

The 12-module 576GB kit fills all DIMM slots with matched 48GB 2Rx8 RDIMMs, giving maximum registered ECC capacity at DDR5 5600 without mixing ranks or speeds.

What does the DDR5 5600 CL46 rating deliver in a real Supermicro H14DSG-O-CPU server?

The modules run at the board's native DDR5 5600 transfer rate with CL46 latency and 1.1V operation, providing the exact timing and voltage the memory controller expects for full-speed stability.

How does the 288-pin RDIMM interface and registered ECC design affect usable performance?

The 288-pin registered RDIMM interface buffers address and command signals, allowing all 12 slots to operate at DDR5 5600 while ECC corrects single-bit errors to prevent data corruption.
