I cannot solve Atikmdag and hear increasing clocks on the card can help. I am by default already at 400/1200 for 2d mode. Will going higher damage the card? I was thinking of trying 500/1200 or even 600/1200.
Here is my attempt at making a profile with identical 2d and 3d settings. Note the 3d settings are default and I just copied them into the Want_0 and Want_1 values. I also matched the voltage setting for all 3 to 1200 instead of 950,1000,1200.
