Eight green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 256GB 8x32GB DDR5 6400 CL52 1.1V ECC Registered RDIMM memory upgrade

SKU CH-FJAF-MJQTW

Eight 32 GB DDR5 modules deliver 256 GB of registered ECC memory at 6400 MT/s with CL52 latency and 1.1 V operation for the Supermicro H14DSG-O-CPU motherboard

  • Capacity256GB (8 x 32GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 256 GB total capacity from eight 32 GB modules for dense server memory
  • DDR5 6400 speed with CL52 latency at 1.1 V for efficient throughput
  • Registered ECC RDIMM design corrects single-bit errors and stabilises fully populated slots
  • 2Rx8 organisation matches the memory controller expectations of the Supermicro H14DSG-O-CPU
  • 288-pin DDR5 form factor fits only boards that require registered DDR5 modules

Server-grade DDR5 kit for Supermicro H14DSG-O-CPU

This 256GB kit (8 x 32GB) delivers registered ECC DDR5-6400 memory at 1.10V with CL52 timing. It is built for administrators and integrators who need maximum capacity on the Supermicro H14DSG-O-CPU motherboard. The 2Rx8 registered DIMMs ensure full population support without signal loading issues.

Replaces partial or mixed-capacity configurations

Moving from a partially populated setup or mixed-rank modules to this uniform 8-module kit lets the memory controller run every slot at the rated 6400 MT/s. The jump is worth it when your workload demands the full 256GB at native speed and you must avoid downclocking caused by population rules or rank mismatches.

Handles large-scale virtualization

The 256GB capacity with registered ECC architecture comfortably supports dense virtualization clusters, large in-memory databases, and high-thread-count compute nodes. It runs out when a workload exceeds the motherboard's maximum supported memory or when a future platform requires a different DDR generation or form factor.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro H14DSG-O-CPU motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the Supermicro H14DSG-O-CPU motherboard requires, and it matches the board's memory-population rules for full-capacity recognition.

What is the correct installation sequence for the eight 32 GB modules on this board?

Consult the Supermicro H14DSG-O-CPU manual for the approved DIMM population order; the kit's 2Rx8 registered ECC modules must be installed in the exact slots the manual specifies to run at DDR5-6400 CL52.

Will the ECC and registered features require any firmware updates or ongoing maintenance?

ECC error correction and registered buffering operate automatically once the modules are seated and the system boots; no firmware updates or periodic maintenance are needed for the memory itself.
