3. It-Tħaddim tal-Mini PC Tiegħek
3.1 Tixgħel/Jitfi
Press the power button located on the front of the Mini PC to turn it on. To turn it off, use the operating system's shutdown function or press and hold the power button for a few seconds.
3.2 BIOS Settings and Power Consumption (TDP) Adjustment
The AOOSTAR GEM12 allows for BIOS adjustments to optimize power consumption (TDP) for different performance needs. You can select between Silent Mode (45W-54W), Balanced Mode (54W-65W), and Performance Mode (65W-70W). For maximum performance, the TDP can be adjusted up to 75W.
To adjust TDP to 75W in BIOS:
- Restart your Mini PC.
- Waqt l-istartjar, agħfas ripetutament il-buttuna Del ċavetta (jew F2 depending on your system) to enter the BIOS setup.
- Innaviga lejn il- Avvanzat tab.
- Agħżel Konfigurazzjoni tal-Enerġija.
- Taħt Konfigurazzjoni tal-Enerġija, agħżel Prestazzjoni.
- To set TDP to 75W, navigate to AMD CBS -> Għażliet Komuni SMU -> SmartShift Control.
- Bidla SmartShift Control biex Manwal.
- Aġġusta APU Only SPPT Limit, Sustained PowerLimit, Fast PPT Limit, u Slow PPT Limit biex 75000 (representing 75W).
- Agħfas F4 u agħżel Iva biex issalva u toħroġ.
- The system will restart with the new TDP settings.

3.3 Adjusting Integrated Graphics Memory (VRAM)
The integrated AMD Radeon 780M Graphics can utilize system memory (VRAM). You can adjust the allocated VRAM in the BIOS to optimize graphics performance, up to 16GB.
To adjust VRAM in BIOS:
- Restart your Mini PC and enter BIOS setup (usually by pressing Del or F2).
- Innaviga lejn il- Avvanzat tab.
- Agħżel AMD CBS -> Għażliet Komuni NBIO -> Konfigurazzjoni GFX.
- Taħt Konfigurazzjoni GFX, agħżel Konfigurazzjoni iGPU u poġġih għal UMA_SPECIFIED.
- Imbagħad, agħżel UMA Frame Buffer Daqs and choose the desired VRAM size (e.g., 8G, 16G).
- Agħfas F4 u agħżel Iva biex issalva u toħroġ.
- The system will restart with the new VRAM settings.
