This update is beneficial to ATi users as it will allow fully smooth playback of high resolution, high definition, videos; Hulu, YouTube, Vimeo, Facebook Video, and others… As browser and flash playback has been CPU dependent in the past the long overdue inclusion of GPU acceleration will be a huge blow against video playback stuttering and choppiness through consistent and high framerate.

Not only unsupported, Mobility Radeons are further crippled by their drivers. Laptop distributors (HP, Dell, Lenovo, etc) limit the clocks on the bundled video cards and restrict access to the GPU BIOS. There are a number of logical reasons behind this, namely warranty overheating issues.

There are a number of ways to work around these restrictions, the best likely being a BIOS mod, as it would allow fluent clock changing through ATT, or other programs. However, some GPUs have their BIOS read and write protected, making the process rather futile.

Another, simpler, method is using a specific driver version. 8.9 and 8.10 Catalysts allow you to overclock when used in conjunction with AMD GPU Clock Tool.

So before we begin, these are the ingredients you want:

*optional components

To begin, uninstall your current drivers. If you have the Catalyst bundle installed, go to control panel, remove programs, ATI uninstall – remove CCC, Install manager, and Display Driver, reboot.

If you are running Windows 7, load up DSEO and enable Testing Mode, reboot computer.

If you do not have an ATI entry to uninstall in remove programs then head over to device manager (Run “devmgmt.msc”), select your display adapter, right click on it and select uninstall. Your screen will probably flash.

At this point you have the option of booting into safe mode, by pressing f8 repeatedly in between bios loading screen and the windows logo, and running Driver Sweeper to wipe all traces of ATI from your computer.

When this is done boot back to windows and extract the 8.10 drivers you just downloaded. Now run Mobility Modder, point it to the ATI directory that was created, and click Modify.

For Windows 7, there is an extra step. Skip this if you are not running Win7.

Locate atikmdag.sy_ in the ATI folder, use

DSEO to sign the file.

Now go back to device manager by running devmgmt.msc , select your display adapter, and press Update Driver. Navigate to Browse fo r File, Pick from list of drivers, select Have Disk, navigate to the ATI directory which was created *\ATI\Packages\Drivers\Display\LH6A_INF and press OK.

You may be prompted whether you wish to install an unsigned driver, press yes. If you have Windows 7, you have one more step. Use DSEO to s ign the “atikmdag.sys” in your /windows/system32/drivers folder. Now you can reboot.

When windows boots back up, you can use the AMD GPU Clock Tool to change your clocks.

When installing ATT, make sure to check Disable Overclocking, as it will not function properly. Read these notes if installing ATT on Windows 7.

As stated earlier, Windows 7 requires digitally signed drivers. This is a bummer if you want to run an awesome application like ATT rather than crappy CCC. The fix, as you may have guessed, relies on DSEO. Download it, run it, agree to prompts, enable TEST MODE, and reboot.
Following the reboot, install ATT but do not launch it. Instead, head over to its installation directory and locate atitray64.sys and atitray.sys – these are the unsigned drivers.

Launch DSEO, select sign a system file, and manually enter atitray.sys and press ok. Do this one more time for atitray64.sys Now you can run ATT without problems.
