How to Update Asus BIOS (4 Methods) Step by Step

Updating your BIOS can bring some benefits, such as new security features and hardware compatibility. However, it can also pose some risks, such as causing system instability or malfunction.

For example, Asus has released some problematic BIOS updates for the Ryzen 7000 processors, which affected their voltage regulation. Therefore, you should only update your BIOS if it is necessary and you are aware of the potential consequences.

Asus provides two convenient tools to help you update your motherboard’s BIOS: EZ Flash 3 and AI Suite 3. EZ Flash 3 allows you to update BIOS from within the BIOS menu, while AI Suite 3 allows you to update BIOS from within Windows.

Before you use either of these tools, you should check your current Asus BIOS version and compare it with the latest version available on the Asus support site. If your BIOS is already up to date, there is no need to update it again and waste your time. You can easily check your Asus BIOS version by following these steps.

Methods to Update

There are four main methods to update ASUS BIOS:

EZ Flash: This method allows you to update BIOS from within the BIOS menu using a USB flash drive or the internet. It is recommended for most users as it is simple and safe.

EZ Update: This method allows you to update BIOS from within Windows using a utility program. It is convenient for users who do not want to enter the BIOS menu or use a USB flash drive.

USB BIOS FlashBack: This method allows you to update BIOS without powering on the system or installing a CPU. It is useful for users who have a new CPU that is not compatible with the current BIOS version.
