Asking for a friend, who wants to overclock his GPU, the R9 390 (non-X).
He asked me for advice to OC his card, however I'm only used to newer Nvidia cards, where you just maximize the power/temp target and core voltage and then start dialing the OC, as the maximum allowed voltage and power settings are hardware capped.

How does this work on this AMD card? Can he also maximize the sliders and just dial in the OC?
