TechPowerUp Radeon Bios Editor v.1.26 is a tool which helps you over-/underclocking and tuning your recent ATI video card. Unlike other programs as Rivatuner for example, RBE will provide a modified version of your video card's original BIOS that you can flash upon your video card.
Added (preliminary) support for Radeon HD 6850 and 6870. Everything _should_ work, except for voltage modding.
