Príčina

The issue has been confirmed and was resolved in firmware version 32.46.3048, released on August 14, 2025.

This is a known NVIDIA issue. The device firmware impacted the training process during PCIe network initialization, and the matter has been resolved starting from firmware version 32.46.3048.

The firmware algorithm has been optimized to improve PCIe link stability. It is confirmed that newly shipped NVIDIA cards already include the updated firmware version 32.46.3048 or later.

Riešenie

Run a full power cycle to verify whether the card becomes detectable again.
