Although it may sound technical, I assure you that with this article you will be clear about what to touch, what to avoid and how to get the most out of your equipment..
How to tell if your PC uses BIOS or UEFI?
The first step in getting your hands on the setup is to figure out what system you have. If your computer is newer than 2012 or has Windows 8 or later, it is almost certain that you have UEFI, but to know for sure you can do the following:
- From File Explorer: Go to the folder Windows, find the subfolder Panther and open the file Setupact.logIf you see that the detected environment is UEFI, you're sure.
- From System Information: Balance Windows + Q (or search in the menu) and type "System Information" or run msinfo32 from Windows + R. Look at the line "BIOS Mode": If it says UEFI, bingo. If it says BIOS, you'll have to adjust what you can within its limits.
How to access the BIOS or UEFI
Entering the BIOS or UEFI setup menu is often the most stressful moment for the uninitiated because you have to press the right key at the right time. Most often, just after starting the computer (before the Windows logo appears), you have to press one of these keys: Del, F2, F10, ESC, or on branded computers some special combination.. Here are some common combinations according to the manufacturer:
- ASUS, ASRock, Acer, Gigabyte/Aorus, MSI: F2 or Del
- Dell: F2 or F12
- Lenovo: F2 or Fn+F2
- HP: F10
- Microsoft Surface: Press and hold the Volume + button
- Sony, Samsung, Toshiba: F2 (sometimes F1 or F3)
If you miss the moment and the computer is already starting up, restart and try again. Another option from Windows 10/11 is restart your computer from the recovery options: Go to Settings > Update & security > Recovery and tap “Restart now” under “Advanced startup.” From there, choose Troubleshoot > Advanced options > UEFI firmware settings.
You can also access using Shift + Reset from the shutdown menu or even create a shortcut on desktop to execute Shutdown /r /fw /t 1 to go directly to the UEFI with a single click.
BIOS/UEFI main menu structure and which options to touch for gaming
Once you're logged in, you'll see that the menu can vary significantly depending on the motherboard and manufacturer. On modern boards you will have a graphical user interface (GUI) where you can move around with the mouse (ASUS, MSI, Gigabyte…), while in portable and OEM equipment is usually a classic MS-DOS style menu controlled only by keyboard.
The most common sections are:
- Main: General equipment information and language settings.
- Extreme Tweaker or Tweaker: Here you manage everything related to the CPU and RAM (overclocking, XMP or DOCP profiles, frequencies).
- Advanced/ACPI/Power Management: Power Options, Peripheral Management, APM, ACPI.
- Boot/Startup: Order and options of Boot of the operating system.
- Monitor: Real-time details on temperatures, voltages, and fans.
- Security: Grid of security settings such as passwords, TPM and Secure Boot.
- Tools: Special tools such as BIOS flashing from USB or network.
- Exit: Save changes, load factory settings, or exit without saving.
Each manufacturer can add their own menus, but the general logic is always the same.
Key Gaming Settings in BIOS/UEFI
Now that you are clear on how it is structured and accessed, Let's get down to business with the settings that really affect gaming performance..
1. RAM memory: XMP or DOCP profiles
Many current RAM modules come with XMP profiles (Intel) or DOCP (AMD) which allow you to automatically increase the frequency and latency to optimal values to maximize performance (instead of the base speed). Enable XMP/DOCP from the Tweaker or Extreme Tweaker tabOtherwise, the RAM will run at standard speed (2133/2400 MHz), even if you purchase 3200 or 3600 MHz modules.
For gaming, It is always worth activating these profiles, as they improve both FPS and system responsiveness and are 100% safe if you use compatible memory and motherboards.
2. CPU overclocking and frequency management
If your processor and motherboard allow it, You can increase the CPU frequency (multiplier) from the BIOS/UEFIFind the options in Extreme Tweaker, Tweaker, or CPU Setup:
- AI Overclocker Tuner: Switch from Auto to Manual or select automatic profiles based on the manufacturer.
- CPU Core Ratio: Adjust the multiplier to increase the base speed of the CPU.
- Core Performance Boost/Turbo Boost: Allows you to activate dynamic frequency boost on modern processors.
- Vcore and voltages: With care, you can adjust the voltages to stabilize the overclock. If you're not experienced, it's best to leave it on Auto.
Important: Improper overclocking can cause instability, reboots, or damage if you overdo the voltages/temperatures. Make sure to monitor temperatures and don't push them too hard.
3. Boot Priority and Mode: Boot Mode, CSM, UEFI vs Legacy
In the Boot section it is crucial to put the Primary SSD as the first boot option to speed up startup. In addition:
- CSM (Compatibility Support Module): If you are using a modern OS and recent hardware, leave it at UEFI, not Legacy. Only run CSM/Legacy if you need to boot older systems.
- SecureBoot: Useful to protect the boot against malware, although with some alternative systems (Linux, games with anticheat) can cause problems. Enable or disable it as needed.
- Fast Boot: Enable fast startup if you're looking for maximum speed when you turn on your PC.
4. Advanced power settings and peripheral management
Within Advanced/Power Management you can optimize the energy management and peripheralsSome interesting options:
- ErP/EuP Ready: If you enable it, your PC will consume less power when it's off, but it won't charge anything via USB when it's off, nor will it wake up when you use the mouse or keyboard. Leave it disabled on gaming computers.
- Power On by PCIe: Allows you to turn on the computer remotely (useful if you use Wake-on-LAN).
- SMT/HyperThreading: It's best to keep it active for gaming, unless there's a specific incompatibility with a title.
- Temperature and fan monitoring: Check that all temperatures are within range (less than 80ºC for CPU/GPU under intensive load). Check revolutions and voltages to avoid problems.
5. Durable disk configuration: AHCI, NVMe and M.2 SSD
If you have an M.2 NVMe SSD, go to storage settings and make sure that:
- The port mode is in AHCI (no IDE or RAID, unless you are setting up a RAID).
- The M.2 slot is configured in PCIe x4 mode to ensure the highest bandwidth (typical on ASUS ROG and similar boards).
- The NVMe driver is enabled if your BIOS offers that option (AMI Native NVMe Driver Support: Enabled).
On ASUS motherboards, search directly M.2 Configuration or Storage Configuration to make sure the NVMe SSD is running at its best.
Security Options: Secure Boot, Passwords, and TPM
Gamers don't only live on performance, it's also important keep the system secure. The BIOS/UEFI allows you to set:
- SecureBoot: It protects against malware at startup, but as mentioned, it can disable alternative systems. Enable it if you're only using Windows.
- Administrator password: Prevents unauthorized access to the BIOS/UEFI menu.
- TPM (Trusted Platform Module): Required for advanced encryption features (such as BitLocker) and to meet security requirements. Windows 11. Activate it if your motherboard supports it.
On Lenovo, MSI, ASUS, and other brands of computers, these options are usually found in the Security menu or in the Advanced tabs.
How to reset and restore the BIOS or UEFI if something goes wrong
You may change a setting and your computer may not boot properly. To resolve this, there are several options for resetting the settings to default values, ensuring your PC boots up again:
- Physical Reset button: Many boards have a dedicated button on the back or inside the case that resets all settings to factory settings. Always consult the manual.
- Jumper on the motherboard: Open the case, locate a jumper near the CMOS battery, hold it for a few seconds, and then push it back in to reset the BIOS. For more details, you can visit This guide on problems with missing files.
- Remove the CMOS battery: Turn off and unplug, remove the round battery for 15 seconds, and then reinsert it. This will erase all your personalized settings.
In the event of any major change, take a photo or write down the original settings so that it can be restored if necessary.
When and how to update the BIOS or UEFI?
Updating the firmware can fix bugs, improve compatibility, or increase performance. However, it should only be done if there's a real need, as a failure can render your device inoperable. The basic steps are:
- Download the latest firmware version from your motherboard manufacturer's official website, making sure you choose the correct one.
- Copy the file to a USB formatted in FAT32.
- Enter BIOS/UEFI and use the manufacturer-specific flashing utility (such as ASUS EZ Flash, M-Flash, Q-Flash, etc.).
- Follow the instructions carefully and never turn off the equipment during the process.
Optimal hardware settings in BIOS/UEFI for gaming
To maximize performance, in addition to optimizing your BIOS/UEFI, you should ensure that each component is operating at its peak capacity. From processor, graphics card, memory, to disks and cooling, all of which will influence the gaming experience.
- Processor: Choose the latest generation models, activate Turbo Boost, and adjust cores or threads as needed.
- Graphic card: Install the latest drivers and set them to maximum performance in the BIOS or using the manufacturer's software.
- RAM: Use at least 16GB, preferably 32GB if you're looking for multitasking or streaming. Activate XMP/DOCP profiles.
