Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 768GB 16x48GB DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM Supermicro H14DSG-OM memory upgrade

SKU CH-GW2J-3ENP0

768GB DDR5-6400 ECC registered kit with 16×48GB modules at CL52, 1.1V, 2Rx8 for Supermicro H14DSG-OM

  • Total capacity768 GB (16 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 768 GB capacity from 16 matched 48 GB modules for maximum density
  • DDR5 6400 CL52 at 1.1 V delivers rated speed without tuning
  • Registered ECC architecture offloads the controller and corrects single-bit errors
  • 288-pin RDIMM form factor fits the Supermicro H14DSG-OM slot specification exactly
  • 2Rx8 organisation enables full population across all channels

Exact-match server upgrade

This 768GB kit contains sixteen 48GB DDR5 6400 RDIMMs built to the Supermicro H14DSG-OM memory specification. Registered ECC architecture and 1.1V operation let every slot run fully populated at rated speed. The modules use major OEM Samsung, Micron or Hynix components for enterprise stability.

Registered ECC RDIMM form factor

The board requires 288-pin registered DIMMs; UDIMM or SODIMM modules will not fit or function. CL52 timing and 2Rx8 rank layout match the controller expectations so the system recognises the full capacity immediately. Verified fitment removes guesswork from population order.

768GB total capacity headroom

Sixteen slots filled with 48GB each delivers maximum supported density for memory-intensive workloads such as virtualisation, in-memory databases or large-scale analytics. Workloads that exceed this ceiling will need a platform with higher per-slot limits or additional memory channels.

Questions about this item

What does the 768GB capacity mean once installed in a Supermicro H14DSG-OM?

The kit fills 16 slots with 48GB modules, giving the full 768GB the board can address when populated per its memory-population rules.

How does the DDR5 6400 PC5-51200 rating limit real-world throughput?

The modules run at 6400 MT/s with CL52 latency at 1.1V; registered buffering lets all 16 slots operate at this rated speed without downclocking.

What physical slot and form factor do these 288-pin RDIMMs require?

They need 288-pin DDR5 RDIMM sockets on the H14DSG-OM; the registered design and 2Rx8 organisation match the board's slot layout exactly.
