Reflashing makes no difference btw.
Issues with F22:
Colour cycle for RGB Fusion is messed up. See video:
https://photos.app.goo.gl/qkNZAsRa33ShaiNC3 instead of cycling through the colours in a smooth, gradual fashion, it cycles smoothly through some but then switches rapidly (not gradual) almost as if it is skipping across (with no gradient). It's not meant to be like this and it wasn't before when I was using BIOS F10.
Another issue I've noticed with BIOS F22: All other SATA plugins (except the boot drive) are not showing up in SATA connections or boot override. See same link:
https://photos.app.goo.gl/qkNZAsRa33ShaiNC3 - This isn't indicative of a hardware issue because the drives are connected and they do work. When I get into Windows 10, sure enough there they are and they perform perfectly fine. Again, BIOS issue.
I won't be using F23 until it is F23Z and has been so thoroughly tested and debugged you could bang it. I have to say whoever is working on the X370 Gaming K7 BIOSes sucks. The BIOSes for the Gaming K7 have been riddled with problems throughout and I found that BIOSes for my old GA-Z77-D3H from the year 1807, were brilliant compared to the mass of oversights the Gaming K7 BIOS tends to have.
Last of all: no, I am not using the horrid, cancerous Fusion desktop app and the equally awful Gigabyte APP Centre.
EDIT: After selecting Optimised Defaults and redoing my BIOS settings, I made sure to go into the RGB Fusion section, click static first then go back to colour cycle. After doing so the pattern of the colour cycle has changed (again), now skipping through several colours jerkily and missing red and yellow completely before dipping the light (almost off) for a brief period when the light turns blue. They all do this, so it isn't an LED issue. This is a control issue likely because of sloppy BIOS development or a bug of some kind. See the new videos in the shared album with the same link as before:
https://photos.app.goo.gl/qkNZAsRa33ShaiNC3I have also posted this on the Official Gigabyte Aorus subreddit.
Edit (again): (the 50s video shows before and during changes to the RGB lights - the 31s video demonstrates what happened after I re-set the colour cycle - basically one buggy colour cycle to another, just with a different pattern).
Edit (again, again): other issue, albeit minor. A delay in activation on PS/2 peripherals - namely, keyboards. I have about 1 second to press DEL to enter the bios on a PS/2 keyboard (USB to PS/2 adapter). It starts way later than USB peripherals for some odd reason).
