This goes for all motherboards, all models. I can leave some last calm words, that the 5800x does work with BIOS 5.10 on the mentioned motherboard, even without the proper update. I was updating the BIOS again with one last try this afternoon as I in theory needed it for the new(ish) Ryzen 7 5800x CPU I just ordered to install Windows 11 upgrade. I have for the last few months (3 to be exact) tried again and again, and can confirm that BIOS updates using Instant Flash for the Fatal1ty X370 Gaming X after update 5.10 do not work, and cannot be found by the Instant Flash update no matter how many times the user will try. you can also receive exclusive bonuses, in-game items and experience the premium gaming feast on the asrock app shopsizedescriptiondownload3.28mbapp shop ver:1.0.41latest bios & driver downloadstep 1click on bios & driver on asrock app shop.step 2click the drivers and driver you wish to update.step 3click update to start. By the above, I mean you cannot accidentally damage your motherboard BIOS memory with an update when the Instant Flash application deems it as broken. I have an ASRock Fatal1ty X370 Gaming X motherboard and I would like to add some reassurance too in my words that if an update is not compatible with you motherboard, the Instant Flash! BIOS update won't find the file.

Some models of motherboard manufactured come with 'buggy' or 'not working' updates to the Bios Flash Update. BIOS Update Procedure Locally (Instant flash) Save the BIOS files on a device such as USB disk (FAT32 format), hard disk (FAT32 format) and floppy drive.

I thought I would lay it out for all of you here, and this goes for all motherboards in general, not specificially ASRock.
