Asus OC bios

Asus OC bios extends the overclocking abilities of a normal Radeon HD7970 bios. I use it when I bench, and turn my card back to my original bios afterwards.

The extended capabilities of the Asus OC bios can only be utilized using Asus GPU Tweak utility

To flash the card, I recommend two apps. The first app is GPU-Z, in which you can backup you daily bios, before flashing the Asus OC bios. The next app is ATIWinflash, which is used to flash the different bios files.

Further more its a good idea to get the latest ATI drivers from benchmark3d.com.

Procedure:

    • Install latest GFX drivers

    • Install ASUS GPU Tweak utils

    • Unzip/Install atiwinflash in ASUS GPU Tweak directory

    • Move ASUS OC bios to ASUS GPU Tweak utils directory

    • Rename Asus.HD7970.3072.120104.bin to Asusoc.bin

    • Run GPU-Z and dump backup of GPU bios

    • Rename Backup bios to Original.bin

    • Move backup GPU bios to ASUS GPU Tweak utils directory

    • Install/Unzip atiwinflash to ASUS GPU Tweak utils directory

    • Download and unzip bios file and put the files in ASUS GPU Tweak utils directory

To flash from windows, you can use my batchfiles, which makes it simple you can use these two files

    • To OC bios, run the file asusoc.bat with "Administrator" rights

    • To original bios, run the file original.bat with "Administrator" rights.

After each change of bios, be sure to reboot the computer.
