Twelve green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 576GB 12x48GB DDR5 6400 CL52 1.1V ECC RDIMM Supermicro H14SSL-NT memory upgrade

SKU CH-BGQD-6R2H1

576GB DDR5 6400 ECC registered RDIMM kit with twelve 48GB modules at 1.1V CL52 for Supermicro H14SSL-NT

  • Total capacity576 GB (12 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 576GB total capacity from twelve 48GB modules for maximum memory density
  • DDR5 6400 speed with CL52 latency at 1.1V for rated server performance
  • ECC registered RDIMM architecture corrects single-bit errors and buffers signals for stability
  • 2Rx8 dual-rank organisation matches the Supermicro H14SSL-NT memory controller expectations
  • 288-pin DDR5 RDIMM form factor fits the motherboard's required slot type

Capacity and Fit

This 576GB kit delivers twelve 48GB DDR5 6400 registered ECC RDIMMs built for the Supermicro H14SSL-NT motherboard. It targets administrators who need the exact rank, voltage and timing combination that board expects for full-capacity operation.

Upgrade Path

The kit replaces partial or mixed-capacity populations that force the controller to down-clock or limit rank-per-channel counts. The jump is worth it when every slot must run at the rated 6400 MT/s without manual timing adjustments or stability compromises.

Headroom and Limits

Registered architecture and on-die ECC keep all twelve modules stable at 1.1V across the full 576GB. The configuration runs out when workloads demand bandwidth beyond PC5-51200 or capacities exceeding the board’s qualified maximum.

Questions about this item

Does the 288-pin RDIMM form factor fit the Supermicro H14SSL-NT motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM modules that match the Supermicro H14SSL-NT motherboard's required form factor and registered architecture.

What is the correct population order for installing all 12 modules on this board?

Consult the Supermicro H14SSL-NT manual for the approved DIMM population sequence; the board's memory rules dictate the exact slot order for full 12-module operation.

Will the 2Rx8 registered ECC modules require firmware updates or battery-backed cache maintenance later?

The modules themselves need no firmware or battery maintenance; ECC error correction operates automatically, and registered buffering is handled by the memory controller.
