576GB DDR5-4800 ECC RDIMM kit for Supermicro

This 12-module kit delivers 576GB of registered ECC DDR5 memory tuned for the Supermicro H14DST-FL motherboard. Each 48GB module runs at 4800 MT/s with CL40 latency at 1.1V. The registered design and on-die ECC suit multi-socket servers that require full population across all channels.

288-pin RDIMM form factor with major-brand DRAM

Modules use Samsung, Micron or Hynix ICs in a 2Rx8 organisation without heat spreaders. The 288-pin RDIMM connector matches the board's DIMM slots exactly, so no adapter or down-clocking is needed. Registered buffering reduces electrical load on the memory controller when all twelve slots are filled.

1.1V operation keeps power draw low at rated speed

Running at the standard 1.1V DDR5 voltage, the kit draws minimal power while maintaining 4800 MT/s throughput. No over-voltage is required to hit the rated frequency, so system fans can remain at baseline speeds. The absence of heat spreaders relies on chassis airflow, which is typical for dense server configurations.

Questions about this item

Does this DDR5-4800 kit run at its rated speed when all twelve slots on the Supermicro H14DST-FL are populated?

Yes, the registered ECC RDIMM design offloads the memory controller so every slot runs fully populated at the rated 4800 MT/s speed and CL40 timing.

What physical slot type does the Supermicro H14DST-FL require for this 12-module kit?

The board uses standard 288-pin DDR5 RDIMM slots; each 48 GB module in the kit matches that form factor exactly.

In what order should the twelve RDIMMs be installed to follow the H14DST-FL population rules?

Consult the motherboard manual for the approved DIMM population sequence; the kit is spec-matched to those rules but the exact slot order varies by board revision.
