How To Update BIOS/UEFI For ROG Strix X570-E Gaming

Introduction to BIOS

How to update BIOS ? Before delving into the process of updating your BIOS or UEFI, it’s important to understand how it works and whether or not updating it is necessary. Equipping yourself with this information beforehand can prove useful when you’re ready to update your device’s firmware.

As technology advances, the term “BIOS” is becoming outdated in the world of PCs and laptops. Despite this, it still persists. The acronym stands for Basic Input/Output System, and it is a chip that allows your device to perform basic startup operations before loading the operating system, such as Windows.

Nowadays, instead of using BIOS chips, PC and laptop motherboards use a new system called UEFI. While it’s possible to run in legacy BIOS mode, most people and manufacturers still refer to UEFI as “the BIOS”.

While there are differences in how BIOS and UEFI work, the process of updating them is generally the same. If you’re looking to update your BIOS, it’s important to know that there are two standards: the traditional type is being phased out and replaced with newer UEFI chips.

However, PCs made before 2007 may still have the older version. UEFI provides a universal standard for all major processor manufacturers, making it a reliable replacement.

More About UEFI

UEFI, or Unified Extensible Firmware Interface, is a newer system that has largely replaced the traditional BIOS in modern PCs and laptops. This firmware initializes hardware during the booting process and acts as a bridge between the operating system and hardware.

Compared to BIOS, UEFI has several key advantages, such as supporting larger disks up to 9.4 zettabytes, faster boot times, and improved security features.

Additionally, UEFI has a graphical user interface, making it easier for users to interact with system settings. Overall, UEFI is a more advanced and capable system that has become the standard in modern devices.

Should You Update BIOS/UEFI?

When it comes to updating your BIOS, it’s important to exercise caution as there is a risk of permanently damaging your device if something goes wrong during the process.

In the event of a power cut or if the computer is turned off during the update, it may become unable to boot altogether. Although unlikely, it’s not impossible.

For this reason, we recommend against updating the BIOS unless you have a valid reason to do so. Valid reasons might include adding support for a new processor, fixing bugs or performance issues, addressing vulnerabilities, or adding new features that you require.

Remember to take all necessary precautions and proceed with care if you do decide to update your BIOS.

How to Identify the Make and Model of Your Motherboard

Before updating your BIOS, it’s essential to identify the model of your motherboard. This is necessary as you will need to download the appropriate BIOS firmware from the manufacturer’s website.

It’s crucial to download the BIOS that is specifically designed for your motherboard model and not just for the brand of the motherboard.

First download CPU-Z from this website and then install it on your PC.

Upon opening CPU-Z, you’ll have access to a range of information about your CPU and other related details. Navigate to the motherboard tab, and you’ll be able to view both the model and brand of your motherboard.

Additionally, the “BIOS” section within CPU-Z will display your current BIOS version. It’s crucial to determine if updating your BIOS is necessary before proceeding with the update. If you already have the most recent version, there’s no need to update it further.

If you prefer not to install any software to obtain information about your motherboard, you can always refer to the motherboard manual or examine the board itself.

The complete model name of your motherboard is typically located somewhere on the board itself. It’s crucial to identify the exact model as there may be slight variations, each with its own specific BIOS.

Additionally, make a note of the revision number, such as REV X.0x, as it may necessitate a different BIOS file than previous board revisions.

How to Update BIOS or UEFI

In this article, we will guide you on updating the BIOS for the ROG Strix X570-E Gaming motherboard. This guide can also be applied to other Asus models or other brands as the BIOS update process is usually similar.

Creating a backup of all important files on your PC is recommended before updating the BIOS. While a failed update doesn’t harm your hard drive data, it can still be a hassle to access them. Although the chances are small, it is still a risk that should be taken into account.

First, you will need to download the newest BIOS version from the Asus website, which in this instance is going to be

Then, extract the compressed file and transfer all the files to your USB drive.

Once the files are transferred to your USB drive, rename the BIOS file to a required filename by ASUS by opening the “BIOSRenamer.exe” file.

After pressing any key to continue, the file will be renamed to a new name such as “SX570EG.CAP,” as shown in the screenshot above.

Update BIOS from the BIOS Menu

Below are the final steps to update your BIOS using the BIOS/UEFI menu. To enter the BIOS (UEFI) menu, restart your computer and press the appropriate key on your keyboard (usually F2, Del or F10). And for this motherboard, you can press F2 or the Del button.

When you’ve entered the BIOS menu, navigate to Tool > ASUS EZ Flash 3 Utility and press enter.

Next, navigate to your USB drive and select the BIOS file “SX570EG.CAP” before pressing the “Enter” key.

The BIOS update prompt will appear, displaying information such as the BIOS version and other details, and will ask for confirmation before proceeding.

After clicking the “YES” button, the BIOS update process will begin, and it may take several minutes to complete. Once the process is finished, you will be prompted to restart your PC.

Finally, after the BIOS update is complete, it’s recommended to check a few things before restarting your PC or laptop. Enter the BIOS by pressing the appropriate key during boot up and check the main settings.

Ensure that the date and time are correct, the boot order is accurate, and everything else looks right. Configure advanced settings such as CPU and memory frequencies if needed, and make sure to save your changes before exiting.

It’s also a good idea to note down previous BIOS settings or know what they should be in case of any issues.


In conclusion, to improve your system stability, increase performance, and add features, updating BIOS or UEFI can be an easy process. However, proceed with caution, backup important files, and follow instructions carefully to avoid issues.

Check the settings after the update to ensure everything is smooth. Updating your BIOS or UEFI can be an investment in the longevity and functionality of your system, if you take the necessary precautions.
