As of today it's dead anyway ,rip 1080 Ti .
Interesting video ,will try to resuscitate one more time the gpu,but i still remain with the question in my mind if it was like this from the begining.(with cap at 6 gb ,crash after).
Check carefully the products you buy,it's your money you loose and nobody will give a fck about it.
I have tons of hardware bought and not tested even for functionality because of lack of time,i will have surprises ,i can bet on it.
