Download link: Radeon Bios Editor v1.27 (149)

RBE is a tool which helps you with 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.
There is no installation required. Just download the RBE.exe and run it. There is just that one single file. No administrative privileges are required to run RBE.
