RBE - Radeon BIOS Editor

Note: Due to a signature requirement on recent AMD cards, this application is no longer supported and working with the latest graphic cards.

If you're a gaming fanatic, you might understand the concept of overclocking and underclocking and be interested in a tool that can help you apply these procedures to some of your computer's components.

RBE - Radeon BIOS Editor is such a utility that can simplify the way you tune your video card by providing you with a modified version of its original BIOS that can be easily flashed.

Since you don't need to install it on the target computer, this application falls in the portable tools category, which means that you just launch the executable and enjoy its full range of options without any restriction.

More so, you can carry it around with you on a CD/DVD, USB flash drive or external HDD or SSD and not worry about it creating files or folders on your computer without your permission nor about it modifying your registries.

Before you can start tampering with settings, you need to load a valid BIOS file into the application that you can later modify. This file includes various pieces information such as the date/time, version string, chip type, copyright message, atomBIOS version, video card vendor and model and more.

After doing so, you can freely modify clock settings by navigating to the designated tab and set values for GPU (MHz), RAM (MHz) and voltage (V) as you see fit. You can also use a clock tuning wizard if you like. Fan settings can also be modified from the proper section.

To wrap it up, if you own an older ATI Radeon card and would like to mess around with its configuration, you might want to give RBE - Radeon BIOS Editor a shot. It's portable, comes with a simple interface and requires no additional configuration.
