Four green DDR5 RDIMM modules without heat spreaders in a kit

NEMIX RAM

NEMIX RAM DDR5 6400 ECC RDIMM 192GB 4x48GB CL52 1.1V 2Rx8 Supermicro H14DSG-OD memory upgrade

SKU CH-88PD-BAX15

A 192GB kit of four 48GB DDR5 6400 ECC registered DIMMs validated for the Supermicro H14DSG-OD motherboard

  • Total capacity192 GB (4 × 48 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Exact-match 192GB kit runs at DDR5-6400 CL52 1.1V so the server recognises full capacity at rated speed
  • Registered ECC RDIMM architecture offloads the controller and corrects single-bit errors for enterprise stability
  • 2Rx8 288-pin form factor matches Supermicro H14DSG-OD population rules for verified fitment
  • Major-brand Samsung, Micron or Hynix DRAM chips deliver consistent quality across all four modules
  • Lifetime replacement warranty with free US-based technical support backs the upgrade

Capacity and fit

This 192GB kit delivers four 48GB DDR5 RDIMM modules built to the exact 288-pin registered form factor the Supermicro H14DSG-OD motherboard requires. It targets administrators who need the full 192GB capacity without mixing ranks or speeds. Buyers who need a different total capacity or a UDIMM form factor cannot use this kit.

Thermals and power

Each module operates at 1.1V with no heat spreader, relying on the server chassis airflow to keep temperatures in check. The registered architecture buffers the address and command signals, reducing electrical load on the memory controller when all slots are populated. No active cooling or additional voltage headroom is specified.

Build integration

The kit matches the board's 2Rx8 rank structure and CL52 timing so the memory controller recognises every module at its rated 6400 MT/s speed. Installers must follow the motherboard manual for approved DIMM population order and maximum supported capacity per slot. The 288-pin RDIMM design prevents accidental insertion into consumer UDIMM or SODIMM sockets.

Questions about this item

How do I install the 288-pin RDIMM modules in the Supermicro H14DSG-OD and what population order is commonly missed?

Power down the server, open the chassis, and insert each 48GB module into the slots specified by the motherboard manual for a four-DIMM configuration; the step often missed is following the exact slot sequence so the memory controller recognises all 192GB at DDR5-6400.

What maintenance or replacement will the registered ECC RDIMM kit need during its service life?

No scheduled maintenance is required; if a module fails the lifetime replacement warranty covers a swap, and ECC continues correcting single-bit errors without user intervention.

What limit appears first when the 1.1V 2Rx8 modules run sustained workloads at CL52?

The DDR5-6400 speed and CL52 latency are the rated operating points; sustained loads stay within the 1.1V specification, so the first limit encountered is the module's maximum rated frequency and timing.
