Hello, I'm new to the forum,
my configuration:
Intel Celeron G3930 7th gen(Kaby Lake)
MSI GAMING Z170A PRO CARBON
Kingston 8 GB DDR4
Intel 120GB SSD
7x Sapphire Rx 480 8GB OC (with modded bios)
EVGA Supernova 1200w

I installed the new BIOS and then installed the modded one, but every time I try to boot into windows it shows a backlit black screen and whenever I try booting a UEFI install usb it shows the windows loading circles and then backlit black screen. I've left it on for 24 hours with the same result.

Without the 4G decoding the system is fine, but whenever I try turning it on the system just does a backlit blackscreen, also I have PEG0 and PEG1 set to Gen1

What should I do? I'm really desperate right now, any help is appreciated.

Hello,
First, install this bios (A single gpu main port) ... https://www.dropbox.com/s/bk22xpc6afayexc/E7A12IMS.7Z?dl=0
Then install windows in UEFI mode. (Before installing, change the partition of the disk to GPT).
After installing windows. Install Amd driver
reboot.
Now activates 4G on the bios, you do not need to activate or change anything else.
Reboot.
Plug all gpu and wait

Good Luck Sorry my english is not very good

I just tried this, it doesn't work. The same thing happened. It shows a backlit black screen after loading the BIOS screen.
I'm using Rufus since you can't only install UEFI windows 10 using Media creation tool.https://i.imgur.com/dj7LdN6.png

So this is what I did:

So it boots with the bios logo.

Then it shows a loading screen without the windows logo.

After that it shows the loading circles with the msi bios for a split second. (literally for 1 second, but somehow I managed to get a picture of it)

Right after it shows the backlit blackscreen.

I have been using the modded version of the bios already. I have also tried the 1.7 Official version. Both do not work.
I also have tried using only 1 GPU(not on riser), no cards(using on board Graphics), 1 GPU(on riser) and all GPU(on risers).
