Ultimate BIOS Settings Guide: Configure and Optimize Your Computer's Performance

It may be recommended to update the BIOS version to guarantee maximum performance out of the system.
Download from the manufacturer's website and install using a USB stick during system boot.
Could be important to secure the best possible compatibility with new hardware.

Usually, F10 brings up the toggle for restoring the factory default settings.
It's always recommended to do this before making any changes to the BIOS settings.

Sets the RAM to its optimal performance settings by regulating Voltage and Frequency.

Used for advanced workstation tasks and will impact gaming performance in a negative way.

Hyper-V and similar virtualization technologies should be disabled.
Such features are used for virtual machines in workstations and have no use in games.

Controversial since it disables a large selling point of various CPUs.
Lowers temperatures which allow for better latency thanks to less risk of throttling.
Usually not well utilized in games and is usually better for content creation apps that are optimized for more threads.
Only recommended for people with 6 or more CPU cores.

"Fast boot" will postpone crucial desktop checks until later and it's recommended to disable it.
Let the computer do a proper check during startup to guarantee flawless operations.

Technology from Intel controls the CPU by changing the clock speed to save power whenever possible.
While it's good for saving energy it may introduce Frame-timing spikes as a result.
Disable to avoid spikes in FPS from changes in CPU frequency.

Set package C-State Limit, if possible, to a lower C-state value to avoid latency from the CPU going in and out of energy-saving states.
Avoid power management options that put your computer to various levels of sleep which affects the performance and spikes in frequency.

Another energy saving feature present in the BIOS menu. It should be deactivated to ensure ultimate performance during gameplay.

The SSD bios settings should be set to AHCI for best load times and performance.
(Only applicable to SATA-drives)

Disable if not needed as it will need to load Drivers and various tools that may interfere with performance.

It's always preferred to use a discrete graphics card for gaming.
Avoid loading additional (Intel) drivers inside Windows
On-board graphics may help with media encoding features.

Set preferred display output to your dedicated graphics card in the bios settings.

Unnecessary devices will require additional drivers which will add additional load to the system.
Avoid onboard audio if you are using a wireless headset or a dedicated DAC.

It’s usually enabled by default, and it is currently recommended to leave enabled on modern systems.
This is part of the Windows bios settings that control how the OS can schedule various operations.

Ensures the latest and fastest communication between your Graphics card and the rest of your components.
The system itself can adjust to lower settings if necessary.

There are barely any benefits from using it and it may slightly interfere with the CPU performance.

RGB functionality and similar technologies are known for introducing Input Lag, Frame timing issues and various problems.
(Sorry, not sorry)

Disable any Active State Power Management (ASPM)/Aggressive Link Power Management (ALPM) settings

This is one of the most important settings - Disables the power saving features in Windows and gives full performance to your games.

It May not be enabled by default depending on your specific setup.
Disable to force the CPU out of System Management Mode (SMM) which may cause system latency.
This happens because of System Management Interrupt (SMI).

It's a clever idea to configure fan settings in bios. Use DC power and set the fan speed to a locked RPM to avoid short spikes of overheat which will throttle your CPU.
