best bios settings for gaming
Listen to this post

BIOS, or Basic Input/Output System, is a program that controls communication between your computer's hardware and its operating system.

It's stored on a chip on your motherboard and is the first thing that runs when you turn on your computer.

BIOS is the underlying software controlling all the hardware at the lowest level.

With millions of hardware configurations, the BIOS settings need to be very general in its approach.

Hence there is room for optimization in dedicated gaming systems.

The Ultimate BIOS Settings Guide

  • What is the BIOS & What can be optimized?
  • Why is it important to optimize the BIOS settings?
  • How to configure BIOS settings for performance

What is the BIOS?

BIOS is the underlying software controlling the various components inside a computer.
The BIOS is running inside the Motherboard and works independently from the OS.

Its memory is stored on a battery located on the motherboard to save the BIOS configuration in case of power and hardware failure.

Why are they important?

Since the BIOS controls everything on the hardware level it is recommended to configure it properly in order to reduce input lag and increase overall responsiveness.

What is BIOS optimization?

Since the BIOS controls performance settings for the CPU and RAM, optimizing its options may show remarkable results.
Enable/Disable devices on the Motherboard, allows you reach peak performance on CPU.

Why it's important to update BIOS

All the major Motherboard brands release BIOS updates regularly.
Updates are primarily released to improve compatibility with newer hardware such as CPUs and RAM.
Other improvements may include bug fixes and general enhancements.

How to reset the BIOS?

If your computer refuses to start, or if you are unable to access the BIOS during startup, you might need to reset the CMOS battery.
Carefully remove the physical battery from the motherboard to reset the onboard memory.
Place it back inside its socket to start over.
Wait 10 seconds before inserting the battery again and start up the system.

How to enter BIOS?

To enter BIOS, restart your computer and press the appropriate key (usually F2, F10, or Del) when prompted to do so.

The key you need to press will be displayed on the first screen that appears when you turn on your computer.

Usually DEL or F2 or F8/12

How to Optimize BIOS Settings for Gaming

If you're a gamer, you may be wondering if there are any settings that you can tweak to improve your gaming performance. The answer is: it depends. Here are a few things to consider:

Always be careful when configuring the BIOS, its settings may prevent the PC from starting correctly. Follow the steps below to set a foundation for increased performance and improved responsive from your system.

But remember to be aware of the fact that some settings may have to be tweaked for your particular PC in order to achieve peak performance.

Total Time: 20 minutes

Update the BIOS

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.

Load BIOS to optimized defaults

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.

Disable Virtualizations

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

Disable Hyper-V

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

Disable Hyper-Threading

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.

Disable Fast Boot

"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.

Disable Intel Speed Shift Technology

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.

Disable CPU C-states

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.

Disable CPU Enhanced Halt (C1E)

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

Set SATA mode

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

Secondary ATA controllers.

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

Disable On-board Graphics

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 Display output

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

Disable Onboard Audio

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.

Enable High Precision Event Timer (HPET)

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.

Set PCI-E to Gen3

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.

Disable Intel Software Guard Extensions (SGX)

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

Disable all RGB

bios settings

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

Disable Platform Power Management

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

Legacy USB Support

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).

Fan Settings


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.

The Results

In conclusion, by following the steps above, you can optimize your BIOS for competitive gaming. This will help you to achieve the best performance possible and give you a competitive edge over your opponents.

Remember to always assess any changes you make to ensure that they are working correctly and don't have a negative impact on your system. If set correctly the BIOS will work for you to make your system more responsive and faster.

Keep in mind that every system is different, and what works for one person may not work for another. It's always a good idea to do your own research and carefully consider the risks and benefits before making any changes to your BIOS.

Good luck in your next match!
