First off, let me start by saying this is my first post and I consider myself a newbie with computers.

(This computer is used for multi-track audio recording as opposed to gaming)

Here's the spot I'm in.

I have an Asus Rog Strix X570E Gaming with Wifi.

It's running an Ryzen 5 3600 without any noticeable problems.

I decided to buy a newer Ryzen 7 5700X.

Asus website says this will work with a Bios upgrade.

I tried to update using the latest Bios update for the wifi version of the board. (Yes, I made sure I was downloading the Wifi version).

I got an error message stating "Selected file is not a proper BIOS file".

(I have used a jump drive that is properly formatted fat 32 with the CAB file renamed)

I decided to try some earlier versions. All failed with the same message.

Here's where it gets strange (to me at least). My Bios reports that I'm running Bios version 1408.

1408 is not listed in the history of downloads for the Wifi version of this board, but it is listed for the non-wifi version of this board. I emailed Asus with the issue and the serial number of the board.

Their reply was, that specific serial# is for a non-wifi X570. And in order for my new CPU to work, I should upgrade to BIOS version 4021 (which is a Bios for the non-Wifi board).

I have sent Asus 3 pics.

One showing the retail box for the Wifi version indicating information showing the serial # I sent them.

Another showing the information regarding the Wifi spec's itself. (Which is on the backplate of my MOBO and i have used.)

and the last pic showing my BIOS post of version 1408.

They have not replied to this yet, but it appears I may have a Wifi board that was flashed by them with the wrong bios.

Sorry for the length of this post.

So I'm stuck as to what to do here. I don't think I should attempt an non-Wifi Bios update on my Wifi MOBO in case it really screws it up.

And all the Bios updates I've attempted with various version of the Wifi Bios's are all giving me the "Selected file is not a proper BIOS file".

Note. I have used various thumb drives, all formatted to Fat32, all Cab files renamed with the file renamer, all cab files at the root level on the drive with no other files on the drive.

Any help (from those who have not fallen asleep yet) is welcome.

Thanks, David.

The best i've found through my testing, or atleast the only one I can play with is version 4021

I've tried 4203, 4204, 3604, 3602, 3405, 2816, 2606, 3001

and every one i try has issues, pretty much each version have their own feeling and different hitreg and lag and i'm so fucking sick of it, i just want to find a bios version that works well- 4021 works well enough but it's not perfect. I can't be the only one who notices a totally different game feel between each bios version? you can even see that your monitor refreshes faster / less blurry moving from 2606 to 4021, there's a huge difference between each bios version and I wish I could find one that just works for me, what works for you guys? I play valorant and csgo, I have 4,400 hours in CSGO, global yadayadaIf you don't believe me, go play a valorant deathmatch on different bios versions and you will see a huge difference. I can't find anyone else talking about how severely a bios version affects hitreg and latency in the game, like it literally affects how fast your mouse moves too? It's not like it's unique to the asus rox 570-e either, the same thing happened with my msi b550-a but I found a good early bios that worked for me, sadly I can't find a nice one with this motherboard so far and it's really annoying me because I literally cannot kill people in deathmatch using some bios versions.
