But the ATITool method does? (saw you got some overclocked scores in the other thread).

Reposting the ATITool method:

1) enable CrossFire mode
2) open taskmanager (crtl+alt+del) and close the two Ati2evxx.exe services
3) Use ATITool Beta 10 and set your fan speeds and voltages and clockspeeds for each card (7100 is slave, 7109 is master), set cards to equal speeds
I dont think ati tool can change voltages for x1600 cards.
I dont see it anywhere.
