(Use Google translate at http://www.google.com/translate_t if you don't know german)

This one supports 3850, 3870 and 3870X2 alltogether. Also, you can edit low and high power 3D clock/voltages separately.

NB: People with 3870X2 - make sure to use google translate and fully read the instructions there. Apparantly you will need to first save the original bios of each gpu separately and then change each one individually but to the IDENTICAL new values and flash both bioses at one sesison (e.g. type atiflash -p 0 bios1.rom once, enter and then type atiflash -p 1 bios2.rom and enter and then restart). I don't have this card and I haven't tried this, so make sure you know what you're doing!
