I'm using sapphire nitro+ 8gig 470 since August 2016. When I buy card it was crashing at all aaa games. Then somebody said if you overclocked it, it's normal. Then I downgraded frequency to 1160 from 1260 (sapphire standart) , and it worked. But then i updated drivers to 17.12.1 and it started crashing at all games even i downgrade frequency. I turned back to 17.6.2. So i can't use new adrenaline drivers. Please help! (sorry for poor english)
