I am lost.
Welcome to the ever-growing club of AMDers that are trying to tweak ACC. My experience is identical to your own, Sandeep. Try to help the weak core and...boom...there goes a different core. Without the ingredients for the ACC 'secret sauce', we'll never get a handle on it. I gave up and set the damn thing back to 'auto' after two evenings of repeated attempts to find some sort of consistency with various settings. Consistant it ain't!
