Well, BatBrink felt no need to show up. Nice one though. Funny!

I was thinking more in line with Brinkman and the Brink signal.

@Ghot: re: The Checksums shown for the BIOSes at least on this Gigabyte site are for the main Capsule (?) file contained within the zip files.

eg: X570 AORUS ELITE (rev. 1.0) Support | Motherboard - GIGABYTE U.K.
eg: Version F37 > Checksum : 77D5

The Checksum (16 bit) appears to be a legacy checksum algorithm.

One Windows program which can compute that checksum is WinHex (I only have an old version).

WinHex Checksum (16 bit) for the Capsule file : "X570AE.F37" (which is inside the zip file).

@das10 If I upload the F36 BIOS file I have, would you be able to check it this way? I can post a Dropbox link?

Sure, I can only but try.
(pn: I can get back to you tonight after dinner.)

Share link X570AXME.F36

The file is extracted directly from the .zip folder, downloaded from official Gigabyte BIOS page for this motherboard.

OK, it shows 98FE.

Same as what I get when I use Q-Flash but it;s not what the website is showing. I've reached out to Gigabyte UK e-support, will see what they say when they respond.

I think it's more likely a Gigabyte error, especially as the Elite BIOS has the correct checksum as you've shown here.

Downloaded the BIOS from Gigabyte again this morning, still getting 98FE checksum so it's not a corrupt download, which would likely fail to install anyway

Update: Gigabyte UK replied requesting a screenshot of the BIOS Q-Flash install screen showing the 98FE Checksum. I've sent them that and await their next reply

Another update: Gigabyte asked me to confirm the checksum, thanks to @das10 for using a 16-bit Hash checker to confirm the checksum is 98FE.

Looks like GB got it wrong on their website.

Final update: Gigabyte have changed the checksum on their website to 98FE, just an hour after I replied to them with confirmation of the value.
