Operating Instructions
Performance Modes
The Nucbox M7 features three adjustable performance modes to optimize power consumption and fan noise:
- Quiet Mode (35W TDP): Ideal for light tasks, offering minimal fan noise (32-35dB).
- Balance Mode (50W TDP): Suitable for everyday computing, providing a good balance of performance and noise (36-37dB).
- Performance Mode (65W-70W TDP): Maximizes CPU and GPU performance for demanding applications and gaming (39-40dB).
These modes can be adjusted within the BIOS settings. VRAM allocation can also be configured up to 16GB in the BIOS.
