echo.
echo Recommended BIOS Tweaks:
echo.
echo 1. Enable XMP / DOCP / EXPO
echo - Use Profile 1.
echo - This makes RAM run at the rated speed.
echo.
echo 2. Enable Above 4G Decoding
echo - Required for Re-Size BAR.
echo.
echo 3. Enable Re-Size BAR
echo - Helps GPU memory access in supported games.
echo.
echo 4. Enable PBO for AMD Ryzen
echo - Use Precision Boost Overdrive.
echo - Use Enabled or Advanced.
echo - Avoid extreme settings unless cooling is good.
echo.
echo 5. Disable CSM
echo - Use UEFI boot mode.
echo.
echo 6. Keep Secure Boot ON
echo - Important for Windows 11 and Valorant.
echo.
echo 7. Keep TPM / fTPM ON
echo - Important for Windows 11.
echo.
echo 8. Set PCIe Slot to Gen 4 or Auto
echo - Use Gen 4 if stable.
echo - Use Auto if issues happen.
echo.
echo 9. Fan Curve
echo - Use performance fan curve.
echo - Keep CPU temperatures safe.
echo.
echo 10. Boot Priority
echo - Set Windows drive first.
echo.
echo Safe Temperature Goals:
echo CPU Gaming: under 85C preferred.
echo GPU Gaming: under 85C preferred.
echo.
echo Notes:
echo Do not disable Secure Boot or TPM for gaming PCs.
echo Do not manually increase RAM voltage for basic clients.
echo Do not promise huge FPS gains.
