I think the only place it will bring harm is to your eyes, but performance wise not a chance when it's only one fin that's like this.
Do to these time I would not ask Gigabyte or the store for a replacement card.
I do not think I seen 0 MHz in Windows what version and build of Windows 10 are you running?
I know I have shown @W1zzard a bug with GPU-Z on how to get 0 MHz to show up but that's with overclocking via the Radeon Adrenalin control panel.
Using AMD's own uninstaller didn't do it for me and DDU is easy to use not really hard.
Jay starts with DDU around 4:48 mins unto the video.
Also afterwards try unlocking the power limit this is what jay from jayztwocents did when he notice something was wrong, I do not know if this still...
Did u run DDU after switching graphics card?
I did that when I had some performance issues with WHQL and Beta drivers this worked with my MSI Radeon RX 6800 XT Gaming X Trio card.
ATM I am running radeon-software-adrenalin-2020-21.3.1-win10-64bit-mar24.exe
Later today or in this weekend I am...
I only 1GBiT on a 10-100TB network so I don't complain :D
I know the ping is off but that's because of a secured VPN connection I use for my home network, if I was at the office there would be like 200Mbit :(
I used a GTX 1080 Ti for 4K gaming on my 4K@144hz IPS panel and I am more happy with my RX 6800 XT then I was with my GTX 1080 performance wise but also the GTX 1080 Ti lacks DSC which does if you want the full chroma subsampling 4:4:4 you cannot go above like 90Hz if I remember correctly, even...
Personally I don't like power line ethernet adapters because you don't know the quality of the power cables in your home if you haven't renovate or built new recently.
Using it on older power lines always makes me fair overheating of the wires or burns in the walls.
I prefer a ethernet cable...
Last Linux based OS I ran at home was PopOS from System76 ran it off a USB to try it on my Dell laptop and it worked great everything worked as far as I can remember no weird issues.
So maybe try as @Frick suggest Ubuntu or another linux instead of Debian.
Asus might just skip the 184.108.40.206 and go straight to 220.127.116.11 for all AMD 500 series boards instead of making 2 bios' and releasing them the same day or with some days apart.
This is just my meaning of this instead of letting people wait for 18.104.22.168.
On my Asus ROG Strix B550-A Gaming on AGESA 22.214.171.124 I got ReSizeableBar aka. SAM to work with my AMD Ryzen 9 3900X.
But I am waiting for the 126.96.36.199 for the USB fix, even I have made a change in the bios it would be nice to have it fixed by AMD.
