Since my driver upgrade to Radeon Crimson relive 17.7. My gpu is locked at 300 mhz and i can't do anything. I tried checking any older versions of crimson, but no luck getting one because im windows 8.1. So could anyone assist me why does that new driver do this to my GPU. My GPU is Amd R7 m260 its a dedicated GPU with intel graphics hd 3000.
