Looks like a bright minded computer geek has found a solution to bypass ATI's locking mechanism to prevent 9700 and 9500 Pro cards from overclocking, which basically shouldnt be an issue because they share the same R300 core GPU/VPU. Kip Hardina therefore is offering modified VGA card BIOS files to be flashed on the corresponding hardware. According to his findings a comparison of the 9700 Pro BIOS, the 9700 non-pro BIOS, and the 9500 Pro BIOS showed only one hexidecimal
value that is keeping the 9500 Pro and 9700 non-pro from overclocking.

ATI is setting the same hex value on the 9500Pro and 9700 non-pro cards to keep them from overclocking. I tested this theory on both a 9700 non-pro and 9500Pro and it works. All of the overclocking utilities functioned correctly...Rage3D Tweak worked great with the new BIOS! You may need to uninstall/reinstall your ATI Drivers and Control Panel.
