Hi there. After a few days of trial and error with driver issues I finally have 2 470s running at 28MH/s each. I can get them to 29 each but one of the cards runs 10C higher than the other card. That causes it to hit the max temp I have set and as soon as it tries to underclock to keep temp my screen goes grety. In fact even when I run them at 28 each and they are stable and can run for days as soon as I stop the mining or the overvlcok the screen goes grey. Are there any thoughts that would stop this or do I need to live with it. I'm using MSI AB to undervolt it will only let me go to -48 with the clock and mem speeds I'm running to achieve 28 - 29. Thanks.
