Il sito Guru3D ha pubblicato, a questo indirizzo, una guida all'overclok per le schede video Radeon HD 7950. Si parte dall'aumento delle frequenze di clock e del powertune dal pannello driver Catalyst, fino ad arrivare alla modifica della tensione di alimentatore della GPU Tahiti Pro tramite il tool AfterBurner. 

"You'll notice that AMD applied restrictions on the clock frequencies. And for good reason, if you like to break free of them you'll need software that can deal with that. AfterBurner can do so, but you'll need to follow these instructions. Now this tweak disables AMD's Powertune. The results may be an instable graphics card. Really anything can happen. If you don't appreciate that, then overclocking is not for you.

Anyway, we recommend you start off with a GPU core clock of 1050~1100 MHz and work your way upwards. with each increase of MHz stress your GPU with a stringent application or game. A full 3Dmark 11 session would be fine.

We ended at 6300 MHz for the memory (1575 MHz x4), and a whopping 1150 MHz on the GPU core (in combination with 65% fan RPM and thus a 1250 Mv voltage tweak)."
