TechPowerUp Radeon Bios Editor v.1.24 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 58x0 and 5970 GPU voltage control.
Added memory voltage control where available (i.e. all cards that utilize a VT1165 in order to control memory voltage, such as 4890, 5870 and 5970 [as far as I know]).
Added GPU voltage control for cards utilizing a L6788A chip. Most 4770s and 5770s use them. Hey, better late than never! :-) Unfortunately, 5670 and 5750 reference design cards can not be supported because their UP6201 chip does not support external programming.
