I followed the directions from this blog to set the gnu frequency, but I get an error when I try to set GPU and CPU clocks manually.
I used amdconfig --odsc==gpu_freq,cpu_freq
and I get the following error:
ERROR:- ATI Overdrive (™) is not supported on the default Adapter - AMD Radeon HD 7600D
I see an option of setting gnu frequency from inside the BIOS, but that also doesn't seem to work. Whatever value I set from inside BIOS, I always see 304MHz frequency of GPU using the amdconfig --odgc command.
