NEMIX RAM 384GB 12x32GB DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM memory upgrade

SKU CH-0EDD-YC7YT

A 384GB DDR5-6400 ECC registered kit of twelve 32GB modules at 1.1V CL52, validated for the Supermicro H14DSG-OD motherboard

  • Total capacity384 GB (12 × 32 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 384 GB capacity in a 12-module kit scales memory-heavy workloads
  • DDR5 6400 speed with CL52 latency keeps data moving at rated throughput
  • Registered ECC design corrects single-bit errors for production stability
  • 1 V operation matches the server controller's exact voltage requirement
  • Validated for Supermicro H14DSG-OD motherboard ensures correct fit and population

Exact-Match Server Kit

This 384GB kit contains 12 modules of 32GB DDR5 RDIMM memory rated at 6400 MT/s with CL52 latency and 1.1V operation. It is built as a registered ECC 2Rx8 configuration specifically for the Supermicro H14DSG-OD motherboard.

Fitment Guidance

The kit suits administrators upgrading the named Supermicro board to its maximum validated capacity using registered DIMMs with ECC. Builders needing unbuffered UDIMMs, non-ECC modules, SODIMM form factors, or lower-density kits for different platforms should look elsewhere.

Deciding Specification

The registered 2Rx8 ECC RDIMM architecture at 1.1V is the single specification that determines compatibility; the memory controller requires this exact rank, buffering, and voltage combination to recognise all 12 slots at the rated 6400 MT/s speed.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H14DSG-OD motherboard?

Yes, the 12-module kit uses the 288-pin RDIMM form factor required by the H14DSG-OD and matches its DDR5-6400 registered ECC specification.

What is the correct installation sequence for all 12 modules on the H14DSG-OD?

Follow the motherboard manual's DIMM population order for the specific CPU configuration; install modules in the prescribed slot sequence so the memory controller recognises the full 384GB at rated speed.

When should the ECC RDIMM kit be replaced or upgraded?

Replace modules if ECC logs report uncorrectable errors or the system fails memory diagnostics; otherwise the registered DDR5 design is rated for continuous server operation at 1.1V.
