RADEON VII 4 pieces do not work, bad luck or AMD falling

[deskless]

I have had 3X Radeon VII fail in recent times.
One of them failed within few hours of installation. All were installed directly on the motherboard.

Someone was telling that we are not supposed to put more than 2 radeon VII on same motherboard. Not sure whether it is correct.
In my case, I had 3 of them and one failed.
