  • 128 GB capacity in a matched 4 × 32 GB kit
  • DDR5 5600 speed rated at PC5-44800 for full throughput
  • ECC plus registered design corrects errors and offloads the memory controller
  • 10 V operation at CL46 matches the board's exact timing spec
  • Validated for Supermicro H14DST-F motherboard with 288-pin RDIMM slots

Exact-match server upgrade

This 128GB kit delivers four 32GB DDR5 5600 RDIMM modules built to the precise rank, voltage and timing the Supermicro H14DST-F memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while correcting single-bit errors before they reach production workloads.

288-pin registered form factor

Each module uses the 288-pin RDIMM layout this board requires — not a UDIMM or SODIMM — and operates at 1.1V with CL46 latency. The registered buffer stabilises signal integrity across all four slots, letting the motherboard recognise full capacity without population-order conflicts.

Replaces partial or mismatched kits

When existing modules are mixed capacities, unregistered or lack ECC, this kit restores uniform 2Rx8 registered operation across all channels. The jump is worth it when silent data corruption or unplanned reboots trace back to memory errors that ECC would catch and correct on the fly.

Questions about this item

What bandwidth does the DDR5 5600 (PC5-44800) interface cap at?

The PC5-44800 rating corresponds to a peak transfer rate of 44800 MB/s, which is the maximum bandwidth this DDR5 5600 kit can deliver on a supported platform.

What physical slot and form factor do these modules require?

Each module is a 288-pin DDR5 RDIMM; the Supermicro H14DST-F motherboard needs this exact registered form factor, not UDIMM or SODIMM.

What is the correct population order for the four 32 GB RDIMMs on the H14DST-F?

The motherboard manual defines the approved DIMM population sequence; follow that order when installing all four modules so the server recognises the full 128 GB at rated speed.
