the 11.6 drivers will let you use aticonfig to set clocks outside the normal config range.
I guess I don't understand how. I've used 11.6 plenty, but I've never had success getting passed the 'normal' range. Is there a list of commands? I use things like "aticonfig --od-enable" "aticonfig --odsc=GPU,mem" "aticonfig --odgc" and so on, but I don't seem to be able to get that to work.
aticonfig --od-enable
aticonfig --odsc=900,300 --adapter=all
change 900,300 for what your lookingto change your gpu and mem clocks.
if your running multi cards just choose the adapter instead of all.
