Exact-match upgrade for Supermicro H14DST-FL

This 288GB kit delivers six 48GB DDR5 4800 RDIMM modules built to the precise rank, voltage and timing the motherboard expects. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

288-pin RDIMM form factor required

The board accepts only 288-pin Registered DIMMs; UDIMM or SODIMM modules will not fit or function. This kit matches that exact physical and electrical interface so the system recognises the full 288GB capacity without population conflicts.

1.1V operation with no heat spreaders

Each module runs at the standard DDR5 1.1V, keeping power draw low even with all six slots filled. The absence of heat spreaders relies on chassis airflow for cooling, so adequate case ventilation is necessary to maintain stable temperatures under sustained load.

Questions about this item

What does the 4800 MHz speed mean once the kit is installed in a Supermicro H14DST-FL?

The modules run at the JEDEC DDR5-4800 rate the board expects, so all 288 GB are recognised at full capacity and operate at the rated 4800 MT/s with CL40 timing.

What does the PC5-38400 designation tell me about the memory interface on this board?

PC5-38400 is the JEDEC label for DDR5-4800; the memory controller on the H14DST-FL uses that standard, so the kit runs at its rated speed without down-clocking.

What physical slot and form factor does this 6 x 48 GB kit require?

Each module is a 288-pin DDR5 RDIMM, the registered DIMM form factor the H14DST-FL requires — not a UDIMM or SODIMM.
