NEMIX RAM 768GB 6x128GB DDR5-6400 ECC RDIMM CL52 1.1V 2Rx4 Supermicro H14DST-F memory upgrade

SKU CH-VYF0-YHVP7

Six 128 GB DDR5-6400 ECC registered DIMMs totalling 768 GB at 1.1 V CL52, validated for the Supermicro H14DST-F motherboard

  • Total capacity768 GB (6 × 128 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 768 GB total capacity from six 128 GB modules for maximum memory density
  • DDR5-6400 speed with CL52 latency delivers rated bandwidth for server workloads
  • Registered ECC architecture corrects single-bit errors and offloads the memory controller
  • 1 V operating voltage matches the motherboard's electrical specification exactly
  • Validated for the Supermicro H14DST-F with 288-pin RDIMM form factor

Exact-match kit for Supermicro H14DST-F

This 768 GB kit contains six 128 GB DDR5-6400 RDIMMs built to the 2Rx4 registered ECC specification the H14DST-F memory controller expects. It runs at 1.1 V with CL52 latency so the server recognises full capacity and rated speed immediately.

Suited for fully populating the H14DST-F

Administrators expanding a Supermicro H14DST-F to its maximum supported memory will use this kit. Builders who need unbuffered UDIMMs, SODIMM form factor, lower capacities or non-ECC modules should look elsewhere because this product is registered ECC RDIMM only.

Straightforward installation with manual checks

The 288-pin RDIMMs seat in the standard DDR5 slots, but the board's population order and per-channel limits must be followed exactly. Skipping the manual's DIMM sequence is the most common cause of modules not being detected or running at reduced speed.

Questions about this item

What motherboard must I already own for this 6x128GB DDR5-6400 ECC RDIMM kit to work?

This kit is verified for the Supermicro H14DST-F motherboard; it requires that board's 288-pin RDIMM slots and registered-DIMM memory controller.

Will these 2Rx4 registered ECC modules run alongside any existing RDIMMs I keep in the H14DST-F?

The H14DST-F's memory population rules determine mixed-rank support; install this 768GB kit in the approved slot order from the board manual and do not mix with UDIMMs or SODIMMs.

After installation, how do I confirm the kit is running at its rated DDR5-6400 CL52 1.1V settings?

Enter the system BIOS or UEFI and check that total capacity reads 768GB, data rate shows 6400 MT/s, CAS latency reads 52, voltage reads 1.1V, and ECC status is enabled.
