Atikmdag patcher, or as it is also called AMD / ATI Pixel Clock Patcher, cancels the verification of the video card driver’s signature after flashing the BIOS, treats Error 43 and removes restrictions from the AMD / ATI driver for high resolutions and refresh rates, removes the limit of the pixel frequency of 165 MHz for 1 -channel DVI and HDMI, the limit is 330 MHz for 2-channel DVI and 400 MHz for VGA.
Version 1.4.10 is compatible with Catalyst 11.9 to Adrenalin 21.4.1. It can be used with future versions if it finds the limits you need.
The program will find all the limits, select “Yes” to fix and re-sign the driver.
Then you can select higher refresh rates using programs for fine-tuning video cards.
