Sapphire’s driver disk is where you will find their Automated Performance Enhancer Utility. Once installed, the utility automatically overclocks your Sapphire Radeon X700 Pro Toxic Edition card to pre-set levels. When enabled, the card’s memory was running at 1GHz, 140MHz faster than stock clock speeds. The card’s core is also overclocked to 472MHz, a 47MHz increase in core clock speed.
Also included with the Sapphire Radeon X700 Pro Toxic Edition is the Redline Tweak Utility. We first saw this program come bundled with the Radeon 9700 Pro Ultimate Edition, with the program being an "all in one" tweaking utility, not only allowing you to manually overclock your graphics card, but also tweak it’s driver settings as well..
