  • Exact 128 GB DDR5 4800 kit with 2Rx8 registered ECC so the H14DST-F recognises full capacity at rated speed
  • 1 V CL40 timing matches the board's memory controller for stable full-population operation
  • Registered architecture offloads the controller enabling every slot to run fully populated at 128 GB
  • ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots
  • Verified 288-pin RDIMM form factor fits the Supermicro H14DST-F motherboard memory slots

System-specific DDR5 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5 4800 Registered ECC modules built to the exact voltage, rank and timing the Supermicro H14DST-F memory controller expects. It is intended for administrators upgrading that specific server platform with validated, fully populated memory.

Registered 2Rx8 architecture at 1.1V

The modules use a 2Rx8 registered design that buffers address and command signals so every slot runs at the rated DDR5 4800 speed when all four DIMMs are installed. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads.

128GB total capacity across four slots

The kit fills four DIMM sockets with 32GB each, delivering the full 128GB the board can address in this configuration. Adding further memory would require a different motherboard or a platform that supports higher-density modules.

Questions about this item

What does the DDR5-4800 rating mean once the kit is installed in a Supermicro H14DST-F?

The memory controller will recognise the modules at their rated 4800 MT/s speed, delivering the full PC5-38400 bandwidth the platform expects.

How does the 288-pin RDIMM form factor and registered design affect compatibility?

The 288-pin Registered DIMM is the exact form factor the H14DST-F requires; the buffered architecture lets all four slots run fully populated without overloading the controller.

What physical clearance does the 4-module kit need inside the chassis?

Each 32 GB module is a standard-height 288-pin RDIMM with no heat spreader, so it fits the regular DIMM slots on the H14DST-F without extra clearance.
