Atikmdag – A Must-Have After Flashing Graphic Cards

Atikmdag – A Must-Have After Flashing Graphic Cards

 402 views

Atikmdag (also known as Atikmdag-patcher) is a special utility that disables device signature enforcement (a security feature) for graphic cards working on AMD/ATI chip-sets to guarantee higher resolutions and frequencies. It deletes constraints related to the clock frequency, utilizes the correct operation of the driver after flashing AMD devices, and lifts overclocking restrictions/limits. What is more, it deals with error 43.

Altogether, there are three versions of Atikmdag that are actively used in the community: 1.4.9, 1.4.8, and 1.4.7. Let’s fasten our eyes to each of these updates, shall we?

  1. Atikmdag 1.4.7

This is one of the oldest program modifications. It suits actuators up to version 20.5.1. Also, it supports the SL-DVI / HDMI limit.

  1. 1.4.8 Atikmdag-patcher

In drivers starting from 20.5.1 update, the file ‘atikmdag.sys’ has been redesignated as ‘amdkmdag.sys’.  Accordingly, this patcher variation is supposed to work properly with new driver-software and address problems of ‘amdkmdag.sys’.

  1. Version 1.4.9

This is the most relevant update. Modification 1.4.9 supports Catalyst 11.9 – Adrenalin 20.12.2. It can be also utilized in newer versions if it finds the drivers you need and their limits. This program variation has a fixed limit HDMI-DVI for 20.11.2 and an HBlank restriction for 20.5.1.

How To Use The Program?

Instructions are intuitive and don’t require some deep knowledge. Just follow the next steps:

Use The Atikmdag Program
  1. Double click the atikmdagpatcher.exe file.
  2. The program will automatically find all the drivers, their limits, and associated errors. Once the searching process is done, a pop-up window with confirmation will appear. Click on the “Yes” button to start troubleshooting and re-flashing the driver.

That’s it! If the process goes amiss, reinstall the current software for your graphic card, or download a more relevant version of the program. Then, reboot the system. After that, you may pick higher resolutions and frequencies using the graphics card configuration software.

Atikmdag Main Characteristics

The basic requirements for the utility are as follows:

Atikmdag for mining
  • Windows OS (Vista or later);
  • GPU 5000 series or newer (AMD devices only).

As for compatibility, we can say the next:

  • Atikmdag-patcher 1.4.7 suits driver updates 20.5.1 and below.
  • 1.4.8 update is relevant to version 20.5.1 and newer.
  • Variation 1.4.9 supports Catalyst 11.9 – Adrenalin 20.12.2.

Atikmdag.sys: What Is It?

As you might have understood, Atikmdag-patcher addresses issues associated with atikmdag.sys. This file is a software component of the ATI Radeon Family developed by ATI Technologies, a Windows driver that allows your computer to communicate with hardware and devices. This means that the driver has direct access to the internals of the operating system, hardware, etc.
In fact, Atikmdag.sys is not essential for Windows and often causes problems. The file is located in the C:\Windows\System32\drivers folder. The driver can be enabled and disabled from the Toolbar – Services or other programs. As this software component often fails after flashing firmware, we recommend you disable or delete it completely.
