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.
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.
ATTENTION !! the latest version at the moment is 1.4.7 No newer versions! Do not be fooled!
