I used 1.52/2.151/2.119/1.510 to get my X1900XT (BJ11 rams) to 702/801 rock solid.
With modified stock cooler (replaced fan with 80mm fan) I max out 72C core, 56C memory under hours of Farcry/LostCoast/AArmy.
With the STI services shut off, Im in "3D" mode all the time, dile is at 48C.... is there a way to get back the 2D/3D control while keeping ATI tool profile in effect for the 3D numbers? Im using the plain Control Panel, not CCC, from the FireGL Cat 6.3 package.
