It is now time for some GPU Modding / Overclocking. #GPUJune2

Back in 2003 ATI decided to Clock Lock all Low-end and Mid-range GPUs.
This includes all Radeon models from the 9000 to the 9600.
This is so SAD... It makes me cry, for real. T-T

So in this video I present all the ways to circumvent this lock. :D
This includes software Tools, Modded Drivers, and BIOS Modding.
A lot of different tools are used here: ATITool, RaBiT, FlashRom.
So this is a nice mini Tutorial on all these methods.

In theory the same tools can be used to unlock pipes on certain models.
This is not covered here, as I do not have any of these cards (9500 and 9800SE).
I might explain this in a future video.

Addition:
The RaBiT Tool can directly open the Bios running on you GPU.
With the option: Open, OnBoard EEPROM
