Six bare green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 768GB 6x128GB DDR5 6400 CL52 1.1V 2Rx4 ECC RDIMM Supermicro H14DSH memory upgrade

SKU CH-0C33-55BNH

Six 128 GB DDR5 registered ECC RDIMMs deliver 768 GB at 6400 MT/s with CL52 latency and 1.1 V operation for the Supermicro H14DSH 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 server density
  • DDR5-6400 speed with CL52 latency delivers rated throughput on the H14DSH
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors
  • 1 V operation matches the motherboard's voltage requirement for stable full-population runs
  • 288-pin RDIMM form factor fits the H14DSH slots exactly as specified

Exact-match DDR5 kit for Supermicro H14DSH

This 768GB kit contains six 128GB DDR5 registered DIMMs built to the precise rank, voltage and timing the H14DSH memory controller expects. It is intended for administrators upgrading that specific motherboard to its full registered ECC capacity.

Registered 2Rx4 ECC at 1.1V CL52

The modules run at DDR5 6400 (PC5 51200) with CL52 latency, 1.10V operation and a 2Rx4 organisation. Registered buffering and on-die ECC let every slot stay populated at rated speed while correcting single-bit errors before they reach the OS.

Full-population stability under load

Registered architecture offloads the memory controller so all six slots operate continuously at 6400 MT/s without down-clocking. ECC correction runs in-line during sustained workloads, preventing silent data corruption and unplanned reboots in production environments.

Questions about this item

What does the 6400 MT/s rating mean once the six 128 GB modules are installed in the H14DSH?

The kit runs at DDR5-6400 (PC5-51200) with CL52 timings at 1.1 V, so each module delivers its rated bandwidth and the full 768 GB is recognised at that speed when populated per the board's rules.

How does the 288-pin RDIMM interface and registered design affect what the memory controller can handle?

Registered architecture buffers the command and address signals, letting the memory controller drive all six slots at full 128 GB per DIMM without signal degradation, while ECC corrects single-bit errors on the fly.

What physical clearance does the 288-pin RDIMM kit need to fit the Supermicro H14DSH?

Standard 288-pin DDR5 RDIMM height; no heat spreader is fitted, so the modules occupy only the DIMM slot footprint and work with the H14DSH's native slot spacing and any low-profile CPU cooler.
