r/ASUS on Reddit: New to PC building. Updating Asus Bios
May 9, 2025 -

Hello,

I believe I need to update the Bios of my Asus ROG Strix B650-A Wifi MB and not sure on how. I went to the ASUS site and downloaded the latest version 3222. Mine is 3024, how ever, their are several versions in between my current and the newest, do I need to download all of them to make sure I have all updates? Also, when I used the renamer, it did not add the .CAP, so I did it myself, is this ok?

No you don't need any of the intermediate BIOS images, just the latest one should be fine. You can do the BIOS upgrade multiple ways. The easiest is to use BIOS flashback. Rename the BIOS file as instructed in your user manual. Place the BIOS file into the root directory of a thumbdrive that has been formatted as FAT32. Place the thumbdrive in the specific USB port for BIOS flashback and then press the flashback button on the IO panel. The LED should flash a few times and the BIOS will be uploaded without the PC being on. It can take anywhere between a few minutes to 10 minutes for the BIOS flash to complete so be patient, do not interrupt this process until it completes. When finished, the BIOS flashback LED should either change colors or will go out. The second way is to do it within the BIOS itselt. Enter the BIOS during boot by pressing F2 or DEL key. Navigate to tools menu. There will be a BIOS flash utility there. Enter the utility and you will be presented with drives on your PC. Find your thumbdrive and select the BIOS file. You will get a visual status bar as the BIOS is being flashed. Do not interrupt the process. When the status bar shows 100% you will be asked to reboot the PC.

I have an ASUS Maximus ROG XIII Hero with BIOS v0707 and would like to update to the latest version (1301) but I’ve never updated a BIOS before.

Any tips/help/guidance?

Thank you

Ps: Asus internet bios update service does not work anymore (I’ve heard this one was the easy way)

r/ASUS on Reddit: Can't update Bios to latest version? :wtf:
February 13, 2023 -

Greetings, I am currently using a ROG STRIX B650E-F GAMING WIFI motherboard, and I am trying to update Bios version from BIOS 0613 to BIOS 0821 .

I tried using the EZ Flash and updating it manually in my BIOS, but after doing so, the PC restarted instantly and CPU red light indicator on my motherboard. I had to do a flashback, back to the BIOS version 0613 to get my system to POST.

Should I try using the ASUS AI Suite 3 V3.03.17 app instead to update BIOS? I am confused, because I believe there is the same functionality occuring between an EZ Flash procedure and updating through the AI Suite application. Any help/tips would be great, as I am trying to get on that 0821 version to better support system performance, 40 series cards, and DRAM optimization.

Cheers!

I have many issues with Asus Motherboards, Asus products in general and AM5 specifically. RMA dramas and horror stories. 
To avoid many issues and to live slightly happier with Asus (like living with a wife that hates you but not as much as you hate her out of convenience); Please make sure to follow these steps or adapt them to your needs:  For Bios updates (sadly frequent for the unfortunate beta testers aka AM5 users) is necessary and must be done; I do the following:

  1. Download latest Bios

    1. From Asus's support Bios Download website for your Motherboard/Device

    2. From ROG forum for Beta Bios For those who dare! (the official moto of ROG by Asus!)

  2. Reboot and reset current bios to defaults (AM5 necessary unfortunately to avoid massive issues)

  3. Boot back to Windows

  4. Disable memory integrity in Windows. Image

  5. Open EZ Update (AISuite)

  6. Load Bios

  7. Change Logo (optional) by clicking the "My Logo" button -> Mine is attached for inspiration, MB is actually my name, funny I know. 

  8. Click on the Flash Bios Button

  9. It will reboot and flash.

  10. Boot to Bios

  11. Reset to default (again!) 

  12. Reboot again back to Bios (Due to some bugs in the past, it's preferred to reboot once you load defaults before changes). 

  13. Make your changes (cannot use a user saved settings across different Agesa version) For me that's turning off RGB and enabling EXPO profile for RAM + adjust Ram training changes frequency and the SAD Asus AI AMD overclocking to (more likely to change after each training) as well as changing optimism rate to 125% (AFAIK will adjust curve optimiser to non 3D cores lower as long as it doesn't crash during use - not during training on cold boots)

  14. Change Secure boot to Enabled (Windows)

  15. Reset secure boot TPM2.0 keys (otherwise windows secure boot will not be enabled in Windows).

  16. Save and reboot

  17. Enter Recovery key for BitLocker if you use encryption.

  18. Boot Windows

  19. Check secure boot is enabled.

  20. Re-Enable Memory integrity in Windows.

  21. Stress test Memory and do your benchmarks.

  22. Test USB ports for failures and speed (Asus MBs are really sh!tty)

  23. Hopefully you won't need to do that for another 15-25 days :'(

Notes:

  • AI suite is uninstalled. However, the only decent, supported and easy way to edit your official BIOS is using EZ Update. For example, and that's the only reason I use the EZ Update is to change the silly ROG logo on boot and put a simpler more my age Logo for boot.

  • I uninstalled all Asus software except for EZ Update (by installing AI suite and removing all components except EZ Update).

*Use this at your own risk, the info there works for me and saves me a lot of headaches and drama, if you don't like any of the steps or don't need it, simply disregard it.
At lease see how I do it and give feedback if you think I can do something better.

I have a new PC build. My motherboard is Asus Rog Strix X670E-A Gaming Wifi with a Ryzen 7800x3D.

The BIOS version shipped with the motherboard and currently installed is v 1415 (5/16/2023).

I'm not experiencing any issues but since the current BIOS is so old, would you recommend updating to the current version (1905 - 2/7/24)?

Thanks for the advice.

To update the BIOS on a B550 motherboard, you can download the latest BIOS files, save them to a USB drive, and then update the BIOS from the BIOS menu. The process may vary depending on the motherboard manufacturer. Steps Download the latest BIOS files from the motherboard's support page Extract the files using a utility like WinRAR Save the files to a USB drive Restart the computer and access the BIOS menu Find the BIOS update option Select the BIOS update file Confirm the update When flashing via bios you can use any USB port in the back.

For the ASUS Prime B550M-A WiFi II, here’s how you can update the BIOS: Download the BIOS Update: Visit the ASUS BIOS & FIRMWARE page for your motherboard, locate the latest BIOS version, and download it. Format your USB drive to FAT32 and extract the BIOS file to the root directory of the USB drive. Make sure the file is not inside any folders. Restart your PC and press DEL or F2 during boot to enter the BIOS/UEFI settings. In the BIOS menu, navigate to the Advanced Mode (press F7 if needed), then go to the Tool tab and select ASUS EZ Flash 3 Utility. Choose the USB drive and select the BIOS file you downloaded. Confirm the update and let the process complete. Ensure your PC stays powered on during the update. Once done, the system will restart automatically. Double-check that you’ve downloaded the correct BIOS version for your exact motherboard model. Avoid interrupting the update process to prevent bricking your motherboard.

r/ASUS on Reddit: Motherboard BIOS update for a noob

I've bought the AMD 5600x, but before switching my actual cpu to this one, I have to update the BIOS to make sure my motherboard will be able to run the recent CPU. Makes sense.

Despite I struggle which method to update the BIOS to choose, I watch this video explaining how to update the BIOS : https://youtu.be/_aBiTr6tpcs

In this video, the guy said that was preferable to update by step ie: using previous BIOS updates before using the newest update, especially if the MB had never been updated before. Is that true?

Because that's the case : This will be my first ever attempt to upgrade my MB I'm using right now since I bought it last year.

Should I use the recent BIOS update , or I have to go through a gauntlet of previous BIOS upgrades before installing the new one ?

My MB is a ASUS ROG STRIX B550-F GAMING

r/ASUS on Reddit: I found an easier way to update ASUS motherboard UEFI BIOS
September 1, 2022 -

Officially, Asus lists 3 ways to update BIOS: two methods need a FAT formatted USB drive, the third method needs AI Suite 3 / EZ Update software. I've found a fourth method than needs neither a USB drive nor any Asus software/bloatware installed, and is actually the easiest to use.

My method uses EZ Flash 3 utility that is baked into UEFI BIOS, but it doesn't need a USB drive to read the new bios update file. What Asus doesn't say and what I accidentally found out it that EZ Flash 3 can read NTFS drives. You can simply download the bios file to your main C:/ (Windows) drive and update from there. Here's are the instructions in detail:

  1. Download the latest BIOS update from ASUS support page for your specific motherboard.

  2. After unzip, a .CAP file will appear, this is the BIOS update file. OPTIONAL: Move this file somewhere where it's easy to navigate, such as C:\.

  3. Restart computer and press F2 to enter BIOS. Select Advanced Mode (F7), go to Tool > ASUS EZ Flash 3 utility. Under Storage Device(s) locate your main drive (It's usually the biggest one). Navigate to the .CAP file and click YES/OK to confirm update.

The bios flashing last about 5 minutes. When the progress bar is completed, click OK to reboot. That's it.

Needless to say, this method will not work if your drive is encrypted or if you have older non-UEFI bios motherboard that doesn't have Flash 3 utility.

It works for me on my B550 mobo and Windows. Let me know if it works for you.

My Asus ROG Strix G16 was working perfectly at night, but in the morning it started restarting randomly and now it won't even turn on, it just freezes with the logo. I've disconnected the RAM and SSD and it didn't make any difference. I suspect it could be the BIOS since I noticed on the Asus website that it was updated 3 days ago, but I don't remember turning it off or interrupting the update. I even fell asleep without shutting down the laptop. Does anyone have any idea what could be causing this issue or has anyone else experienced something similar?

So I have an Asus A320M-K Prime motherboard that i wanted to do a BIOS update. I have that motherboard since I think around 2018 and Its BIOS is still currently on version 4027 I think if im not mistaken. My questions is this:

  1. is it safe if i just update the BIOS straight to the latest stable version, which i think is Version 6042?

  2. Currently the CPU that is installed to that motherboard is Ryzen 5 2400G, will i lose support to this CPU?

  3. Any reason not to do this update?

My main reason in wanted to conduct this update is that my brand new is under performing, which i believe is because of the BIOS version is the culprit.

Updating BIOS... Necessary? : r/ASUS
March 16, 2024 - AMD's and ASUS's BIOSes have been a shitshow for AM5, and still kinda are. Otherwise as I understand it, it wouldn't matter much performance-wise and any performance increases would just be from tweaking overclocking/boost-clock behavior. Typically BIOS updates are for hardware compatibility (particularly new RAM) and security updates (for CPU vulnerabilities and pre-boot encryption).
