Two green DDR5 RDIMM modules side by side, no heat spreaders

NEMIX RAM

NEMIX RAM DDR5 6400 ECC RDIMM 32GB (2×16GB) CL52 1.1V 1Rx8 Supermicro H14SST-GE

SKU CH-FQF0-7376N

32 GB DDR5 6400 ECC registered RDIMM kit (2 × 16 GB) validated for the Supermicro H14SST-GE motherboard

  • Capacity32GB (2 x 16GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • Exact-match 32 GB kit runs at rated DDR5-6400 speed
  • Registered ECC design corrects single-bit errors automatically
  • 1Rx8 1.1 V CL52 timing matches controller expectations
  • Verified fit for Supermicro H14SST-GE motherboard
  • 288-pin RDIMM form factor supports full-slot population

Exact-Match Server Upgrade

This 32 GB kit contains two 16 GB DDR5-6400 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14SST-GE memory controller expects. The modules install as a matched pair so the board recognises full capacity at rated speed without manual tuning.

Low-Voltage Registered Operation

Each module runs at 1.1 V with CL52 latency in standard 288-pin RDIMM form factor. Registered buffering reduces electrical load on the memory controller when every slot is populated, while on-die ECC corrects single-bit errors before they reach the operating system.

Population-Rule Dependent Fitment

The kit fits only systems that accept 288-pin DDR5 RDIMMs and follow the motherboard's approved population order. Builds requiring UDIMMs, SODIMMs, non-ECC memory or different voltages cannot use these modules; consult the board manual for supported capacities and slot sequence before installation.

Questions about this item

How do I install the 288-pin RDIMM kit in the Supermicro H14SST-GE and what step is often missed?

Power down, open the chassis, and align each module's notch with the slot key before pressing firmly until both latches click. The step most people miss is following the motherboard's exact population order for 1Rx8 Registered DIMMs so the memory controller initialises every rank at DDR5-6400.

What maintenance or replacement will this DDR5 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required. ECC corrects single-bit errors automatically. Replacement is only necessary if a module fails, which is covered by the lifetime replacement warranty.

What limit appears first when the 1.1V CL52 kit runs sustained workloads on this board?

The registered buffer and on-die ECC keep signal integrity at the rated DDR5-6400 speed, so the first limit is usually the platform's maximum supported capacity or thermal envelope rather than the memory's own timing or voltage ceiling.
