Four green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM DDR5 5600 64GB (4x16GB) CL46 1.1V ECC RDIMM Supermicro H14SST-G memory upgrade

SKU CH-41RE-1R0XE

A 64 GB DDR5 ECC registered RDIMM kit of four 16 GB modules running at 5600 MHz CL46 and 1.1 V, validated for the Supermicro H14SST-G motherboard

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 64 GB kit (4 × 16 GB) fills every slot at rated DDR5-5600 speed
  • CL46 latency and 1.1 V keep the memory controller within spec for reliable operation
  • Registered ECC RDIMM design corrects single-bit errors and supports full-capacity population
  • 288-pin DDR5 form factor matches the Supermicro H14SST-G motherboard exactly
  • Built with major-brand Samsung, Micron or Hynix chips for enterprise-grade stability

Exact-fit DDR5 upgrade for Supermicro H14SST-G

This 64GB kit contains four 16GB DDR5 5600 RDIMMs built to the exact rank, voltage and timing the motherboard expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. Modules arrive as a matched set so the server recognises full capacity immediately.

288-pin registered form factor with no heat spreader

The RDIMM design offloads the memory controller for stable operation across all populated slots. Absence of a heat spreader keeps module height low for dense chassis airflow and simplifies visual inspection during maintenance. Each DIMM uses 1Rx8 organisation and major OEM chips from Samsung, Micron or Hynix.

Low-voltage DDR5 at 1.1V for efficient server

Operating at 1.10V reduces power draw per module while maintaining CL46 latency at 5600 MT/s. Registered buffering and ECC together prevent silent data corruption and unplanned reboots under sustained workloads. Verify population order in the motherboard manual before installation.

Questions about this item

Does the DDR5-5600 interface cap the kit at 5600 MT/s on the Supermicro H14SST-G?

Yes, the kit runs at DDR5 5600 (PC5-44800) with CL46 latency at 1.10 V, matching the board's rated speed for this configuration.

What physical slot and form factor does this 288-pin RDIMM kit require on the H14SST-G?

Four 288-pin DDR5 RDIMM slots; the modules are registered ECC 1Rx8 with no heat spreader, so they fit standard server DIMM sockets.

What population order should I follow when installing all four 16 GB modules?

Consult the Supermicro H14SST-G manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots fill first.
