Ok now i tried everything…
I put my card in another pc running windows 7 running all at stock speeds and, there i dont have slowdowns there it just make a BSOD, im sure it got enough voltage coz its a corsair 1000w, i got 2 older 7970 cards and they work perfectly in both machines.
I tried with some other ram aswell.
Should i RMA the card or what.. ???
