RBE is a handy tool to modify several interesting parameters in ATI BIOS files. It focuses on fan and clock settings as these are the most important things to most users. BIOS modification is an alternative to using memory resident tweaking utilities such as RivaTuner, ATI Tray Tools or ATITool. But RBE can do more than that: It will balance the BIOS file's checksum, lets you modify the Overdrive settings, enables superior PowerPlay functionality for some video cards, contains a CCC profile editor for hidden features of the CCC and much more. Main Features Can display and change a lot of information strings inside the BIOS file, including Device ID and vendor ID. Accesses every PowerPlay state and can change GPU clocks, RAM clocks and voltage for each of them seperately. Displays the PowerPlay structure of the BIOS. Also displays the voltages the card can make use of. Can graphically display and modify four different fan controllers in a very comfortable way and automatically figures out which controller is used for a particular BIOS. RBE modifies the Overdrive signature of a BIOS to enable a higher overclocking limit. Signatures can also be extracted and saved to a file. Will make the annoying spin up bug some cards have vanish. Enables superior PowerPlay. Contains a profile editor for accessing hidden CCC panel features. Acquires and flashes BIOSes all from within RBE using the built-in WinFlash interface.
