576GB DDR5-4800 ECC RDIMM kit

This 576GB kit contains twelve 48GB DDR5-4800 registered ECC modules built to the PC5-38400 standard. Each DIMM runs at 1.1V with CL40 latency and a 2Rx8 organisation. The 288-pin RDIMM form factor is the exact type required by the Supermicro H14DST-F motherboard.

Suited for fully populated H14DST-F servers

Administrators expanding a Supermicro H14DST-F to its maximum supported capacity with registered ECC memory will find the correct rank, voltage and timing in this kit. Builders who need unbuffered UDIMMs, SODIMMs, non-ECC modules or a different DDR generation cannot use these DIMMs.

12-module population requirement

The kit delivers 576GB only when all twelve slots are filled with the supplied 48GB RDIMMs. Partial population will not yield the stated capacity and may violate the motherboard's memory-population rules.

Questions about this item

Does the Supermicro H14DST-F need all 12 slots filled for this 576GB kit to operate?

The H14DST-F has 12 DDR5 RDIMM slots; populating every slot with the 12x48GB modules delivers the full 576GB at DDR5-4800, but the board will also run with fewer modules installed following its population order.

Can I mix these 48GB 2Rx8 DDR5-4800 RDIMMs with smaller DDR5 RDIMMs already in the server?

Mixing different capacities or ranks is possible if the motherboard's population rules allow it, though the memory controller will run all modules at the lowest common speed and timing.

How do I confirm the kit is running at DDR5-4800 CL40 1.1V after installation?

Check the BIOS memory information or a tool such as dmidecode; it should show each DIMM at 4800 MT/s, CAS 40, 1.1V, and the total capacity at 576GB with ECC active.
