Quick Start & Pro Tips
Checking PCIe Resizable BAR Status
- Launch GPU-Z.
- Click the Advanced tab.
- Use the drop-down menu at the top to select PCIe Resizeable BAR.
- Review the eight status requirements to determine why the feature is enabled or disabled on your system.
Why: This is crucial for modern gaming performance; verifying the status of Resizable BAR (or Smart Access Memory) ensures your CPU can access the full GPU memory, maximizing frame rates.
Enabling Background Sensor Logging
- Click the Settings button (wrench icon) in the bottom-right corner.
- Navigate to the Sensor Settings tab.
- Check the box labeled Update sensor reading in background.
- Close the settings window and go to the Sensors tab to begin logging.
Why: Enabling background updates ensures continuous, accurate real-time sensor tracking even when the main GPU-Z window is minimized, which is vital for capturing thermal throttling events during intense gaming sessions.
Viewing ASIC Quality for Overclocking
- Launch GPU-Z.
- Click the Advanced tab.
- Select ASIC Quality from the drop-down menu.
- Note the displayed percentage, which indicates the GPU’s theoretical quality.
Why: The ASIC Quality percentage is a key metric for enthusiasts, as a higher value often correlates with a GPU that requires less voltage to maintain high clock speeds, suggesting better overclocking potential.
