128 GB DDR5 ECC RDIMM kit for Supermicro H14DST-F

This 128 GB kit contains four 32 GB DDR5 6400 RDIMM modules rated CL52 at 1.1 V. Registered ECC architecture and 2Rx8 organization match the memory controller requirements of the Supermicro H14DST-F motherboard for full-capacity operation.

Verify DIMM population rules

Before ordering, consult the Supermicro H14DST-F manual for supported DIMM population order, maximum capacity per channel, and any BIOS version requirements. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function.

Replaces smaller or slower DDR5 RDIMM configurations

This kit upgrades from lower-capacity DDR5 RDIMM sets or slower speed grades that limit total memory bandwidth. The jump is worthwhile when your workload needs the full 128 GB at the board's native 6400 MT/s with ECC protection.

Highlights

  • DDR5 6400 speed with CL52 latency at 1.1 V
  • ECC and registered design prevents silent data corruption
  • Verified fit for Supermicro H14DST-F motherboard
  • Lifetime replacement warranty with US-based technical support

Questions about this item

Does the kit include four 32 GB modules or do I need to buy extra sticks?

The kit contains four 32 GB DDR5 RDIMM modules for a total of 128 GB, so no additional sticks are required.

Should I choose a different speed or latency for the Supermicro H14DST-F?

This kit runs at DDR5 6400 with CL52 at 1.1 V, matching the exact speed, latency and voltage the board expects for full-capacity operation.

Will the registered ECC design actually run at 6400 MT/s when all four slots are populated?

Yes, the 2Rx8 registered ECC modules are spec-matched to the motherboard's population rules, allowing all four slots to operate at the rated 6400 MT/s.
