i can overclock on 11.5, using amdoverdrivectrl to downclock mem outside bios limits, and gpu clock rise only to bios limits

with 11.6 and 11.7 u can set whatever you want, but cpu usage bug forces me to rollback to 11.5
Bummer. What's the cpu usage bug? I haven't noticed any problems -- top reports about 5% cpu usage with 4 instances of phoenix running.
