bought 2 cards. (11196-19-20G) tried to overclock them. both crashed. got new ones. tried to overclock from 925 to 950. crashed.
now I stopped overclocking and they are doing fine. arround ~550khash per card at 60-65C

1 question. If you overclock, do you need to put the boost option on or off? so overclock from 850 or from 925?
