ATIKMDAG PATCHER v1.4.14: Download AMD/ATI Pixel Clock for Windows

AMD / ATI Pixel Clock 1.4.7 Atikmdag Patcher: Скачать для Windows


ToastyX’s AMD / ATI Pixel Clock Atikmdag Patcher has long been used to modify AMD / ATI video drivers to provide better performance by removing the 165 MHz clock limit for single-channel DVI and HDMI, the 330 MHz limit for dual-channel DVI, and the 400 MHz limit for VGA Which is useful for everyone who is mining with ATI / AMD GPUs. This tool also has the ability to fix video drivers and remove BIOS signature verification.

There are other solutions that allow you to override the BIOS signature verification, but using the AMD / ATI Pixel Clock Patcher tool is by far the easiest. The current latest version 1.4.7 is compatible with Catalyst 11.9 to Adrenalin 19.9.2, although it can be used with future versions. All you have to do after installing the AMD video driver is to download the tool and run “atikmdag-patcher.exe”, then just reboot.

Known issues:

Legacy drivers may have issues with HDCP and video acceleration with the patch. Workarounds for video playback issues:

  • Disable hardware acceleration in the Flash Player settings (right-click on any Flash video and click “Settings…”).
  • Use the Codec Tweak Tool to disable DXVA hardware acceleration under “Various Tweaks” (in the “Miscellaneous” section).

Older cards require the “LCD standard” vertical blanking/total to reduce the memory clock when idle. Horizontal values can still be reduced if necessary. Newer cards can handle some lower values depending on the resolution and refresh rate.

Older cards have a design limitation unrelated to the patch that causes video acceleration to scramble the screen if the vertical blanking/total is below standard with the video card’s memory overclocked or with multiple monitors connected. Skype is known to trigger this problem. Either don’t overclock the video card’s memory, or use the “LCD standard” vertical blanking/total in CRU.
