.40 file extension for BIOS? Should I rename to .exe?

[Tronlo]

I am trying to update the bios of ASRock x370 Killer SLI. I downloaded the latest bios, version 2.40, from their main website. The problem is that the bios update file is .40 extension, and that doesn't seem right. I do not know whether I should change it to .exe, since in the manual for bios update available online, it shows that the bios file is .exe...

I can't understand why a company would name their file like that. And this seems to be common too. Thank you for your help.

The tool can't open the .40 file?

You don't do anything with that file - just unzip it and save to usb stick, under the same name, exactly as written in step 1 of that guide. It's not a Windows file, it does not have extension.

I am getting 'no image file detected.' notification when I press Instant Flash in bios. I made the USB my primary device and it is a FAT32 (It is a brand new SandDisk USB with 3.0 support, I have it currently connected to the 2.0 port, however.)

I have restarted after making the usb the primary boot device.

Wait a sec. Is your mobo Killer SLI OR Killer SLI/ac? BIOS file for one is X370KLI2.40, for other it is X370KLA2.40. If you downloaded wrong BIOS file, name will not match with what Flash expects.

Ahh sorry thank you for ur help but turned out I downloaded driver for x370 killer ac not x370 killer like I was suppose to. Naming conventions are awful.
