Hi, i have a 4096MB Asus Radeon R9 290 DirectC U II OC which crashes all the time since I bought the card. I used Afterburner to clock the card down and ervything works fine. After re-installing my system I installed the new Amd Radeon 17.7.2 drivers and Afterburner, but i wasn't able to clock down the card. So I installed Afterburner 4.4.0 Beta 16 and downclocking worked again. But I still have a problem playing Overwatch. The card is clocked down, I start playing Overwatch and ervything is fine. I tab back into windows, check afterburner, card is clocked down, everything fine. At some Point, Overwatch crashed with "your rendering device has been lost". When I then check afterburner, I see that the card is not clocked down anymore. I don't know why Afterburner "looses" the clock down at some point during the game. Anyone has an idea what to do? Thanks a lot!
