So with this VGA all my games crashes after few minutes of playing and sometimes pc restarts. And often my internet browser crashes. Can be something wrong with ATI Overdrive? What GPU Clock and Memort clock should be (mhz)? And what fan speed should it be? Now GPU clock is 775Mhz, Memory clock - 950Mhz, Fan speed - 16% and temperature ~73*C. Im sure my VGA drivers are newest and works fine.
