Not to sound rude but you are all wrong. There is a mod and overclocking utility for 9600 as I downloaded it and have it myself. I too wanted more speed and grunt from my 9600SE but it always told me that it was LOCKED and could not be changed. I scoured the net and found some tools, so I modded it. It used to run at Core 324.00mhz and Memory 202.50mhz which was a little slow for the games that I was playing. After playing around with it for a little while I eventually got the Core running smoothly at 396.00mhz and Memory at 219.60mhz. That is quite an increase in performance for a graphics card. It was both a speed increase and visual performance.
The link for the control panel and display driver to unlock the card is:

The ATI Tool for modding and overclocking the card is as follows:

NOTE: This mod will not work on a regular ATI driver. You need the modded driver to unlock it before it will work.
Any more info or instructions just email me.

Happy overclocking people and good luck.
