Crossfire in my hands now too ... ~8)

Actually, you can overclock using the method Macci proposed up there a ways. Using ATItool seems to work for me now for some reason. I upped my score to like 15700 on air just trying it once. You just have to switch between the two cards listed in ATItool and make identical settings for each.

Thanks for confirming this

I think that this is already a fairly quick and easy way to OC R520 CF.

That method sampsa doesnt work for the x1600

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
