ATi Radeon 9500 Pro and 9700 overclock, that's how it works!

ATi Radeon 9500 Pro and 9700 overclock, that's how it works!

It's strange: While graphics cards with ATis Radeon 9700 Pro can sometimes be overclocked significantly, pixel accelerators based on the Radeon 9700 or 9500 Pro are not allowed to run even one MHz above the specifications. Clearly, ATi must have helped here.

After all, it's no secret that the Radeon 9700 Pro, The only difference between the Radeon 9700 and Radeon 9500 Pro is the memory interface used, as well as the chip and memory clock, while the R300 graphics processor is used in all three. Attempts to overclock with, for example, Powerstrip only lead to success with the Radeon 9700 Pro, the other competitors vigorously defend themselves against a higher chip or memory clock.

The reason for this is the Radeon in the BIOS 9700 and Radeon 9500 Pro cards can be found. A special hexadecimal value prevents overclocking. In order to unleash the potential of the Radeon 9700 and Radeon 9500 Pro, you only need a slightly modified graphics card bios that changes this hex value. Modified BIOS versions are already available on various pages on the Internet. Software for flashing ATi graphics cards is also available. With all of this, you should be aware that such an intervention is anything but harmless and will void your warranty.
