so I recently got a second 6870, one thing is there is a bit of a coil whine at 100% load, is this my PSU being stressed? I have a Corsair 750TX. Also, most utilities I use, If I got past like 950 core, the computer freezes and bluescreens, is this remedied by increasing the voltage? I that safe? Also what is a good overclocking utility, when I use afterburner with 2 cards it often crashes/freezes/bluescreens, but this didnt happen with one card.
