Requirements for AMD/ATI Pixel Clock Patcher:

The AMD/ATI Pixel Clock Patcher has a few requirements that must be met in order to use the tool:


Blue screen of death

Atikmdag sys errors often appear on a blue screen due to incorrect driver installation. It is also often caused by driver corruption; it occurs on AMD and ATI Radeon video cards. In most cases, reinstalling or updating the driver solves the problem. However, this is not always effective.

Code 0Х0000003

This code points to a completely different problem, most likely a conflict with the Win32K video driver. Fixing the problem is simple. Just download the desired version of the patch. When installing a video driver, always run Software Update in automatic mode.

Advantages and Disadvantages

Atikmdag-patcher is a tool that catches the attention of many users of AMD Radeon graphics cards, especially those involved in cryptocurrency mining. This tool promises to unlock the potential of graphics cards by increasing their performance and, consequently, mining income. However, like any tool, atikmdag-patcher has its advantages and disadvantages, which should be considered before use.


  1. Increased Hashrate: One of the main advantages of atikmdag-patcher is its ability to increase the hashrate of AMD Radeon graphics cards when mining cryptocurrency. This can lead to increased mining profitability.
  2. Unlocking Potential: Atikmdag-patcher unlocks restrictions imposed on AMD Radeon graphics cards by drivers, allowing them to operate at full power when performing mining computations.
  3. Free to Use: Atikmdag-patcher is available for download and use for free, making it an attractive choice for many users.


  1. Loss of Warranty: Using atikmdag-patcher may result in the loss of warranty on your graphics card. Many graphics card manufacturers do not support the use of such software and consider it a violation of warranty terms.
  2. Security Risk: Downloading and using third-party software like atikmdag-patcher always carries some security risk. There is a possibility of downloading malware or compromising system security.
  3. Negative Impact on Hardware: Improper use of atikmdag-patcher or applying incompatible versions may lead to a negative impact on your hardware, including graphics card damage or system crashes.

Troubleshooting: Fixing BSOD Caused by atikmdag.sys Replacement

When launching a new program, the old atikmdag.sys file is sent to System32\drivers, potentially causing the operating system to use the old version of the file instead of the new one. This can lead to compatibility issues and system crashes.

To fix this problem, follow these steps:

  1. Rename the old atikmdag.sys file in System32\drivers by adding the extension .sys.old to it.
  2. Move the new atikmdag.sys file, located in the ATI folder on the desktop.
  3. Open Command Prompt through the Start menu.
  4. In Command Prompt, navigate to the desktop (type chdir Desktop and press Enter).
  5. Use the Expand.exe command to unpack the new atikmdag.sys file (type Expand.exe atikmdag.sy_ atikmdag.sys).
  6. Copy the new atikmdag.sys file from the desktop and replace the file in System32\drivers.
  7. Restart the system.

After completing these steps, the problem should be resolved. If it persists, it is recommended to check the hardware for possible issues.”
