Common BIOS/UEFI Settings
- Boot Priority: Select which device to boot from first.
- XMP Profiles: Enable for overclocked RAM speeds.
- Fan Control: Adjust speeds for cooling fans.
- Secure Boot: Security feature to prevent unauthorized OS loading.
- CPU Settings: Overclocking, voltage adjustments.
- Storage Settings: RAID configurations, AHCI mode.
- Hardware Monitoring: Temperatures, voltages, fan speeds.
Updating BIOS/UEFI
- Always update firmware cautiously, following manufacturer instructions.
- Use official tools or utilities provided by motherboard vendors.
