I did the config file with Afterburner and I thought you also had to fill in the EULA text

that is a guide to unlocking Afterburner
it worked for me
really no limit on core/mem with that change
but I found Afterburner to be very "glitchy"
caused instability for me
I switched to ATI Tray Tools

That works well for me
the GUI is not the fanciest
actually just works out of your taskbar as an icon
really easy to set profiles
Nortons 2011 sees it as a security risk because of a low level driver installation causing a false positive
scanned with MalwareBytes,Kaspersky and Mcafee Stinger and came out great
try Afterburner first and see if it is running well for you
alot of people review it as a good program
for me it caused issues
