The beta BIOS has been removed. And yes - I did try the BIOS. It does NOT support ANY overclocking. I was not able to check its actual compatibility as I only have a 1090T.
You would be far better off with a new MB that ACTUALLY supported your processor. Take Gigabytes advice - they removed the beta BIOS for a REASON.
The main reason is that they want you to buy ,which is perfectly ok ,they are making hardware to sell and make profits.
The other reason is that some useless features like unlocking cores or the network card feature regarding networkboot are not present due ot lack of BIOS chip space.Installing the beta for FX though would have no impact on the unlocking features as FX are locked in this aspect.
The only question is if the FX will perform properly and if the FX BSOD fixed with later BIOS-es will happen or not.
The lack of BIOS support on the other hand for this mobo is not a good thing.just discovered that the board has issues with some bootable USB sticks opposed to the 970 based board i have.And this is annoying.
I can upload the 2 beta BIOS-es stated to support FX at that time if Absic or DarkMantis allow but it s the users risk.
The strange thing would be that the FX to work just fine with that beta BIOS.
