A quote from the article:
Finally we have the Smart Switch, which controls the dual BIOS that Palit has used with this card. In "normal" mode, the card operates at 750 MHz core / 950 MHz memory. When "turbo" mode is engaged, the card is overclocked to 775 MHz core / 1000 MHz memory - talk about user friendly overclocking!
