How to Solve Error Code 43 in AMD Radeon GPU

AMD is a company known not only for its processors but also for its Radeon graphics cards. If you love computer games, chances are your computer is equipped with a Radeon graphics card. Although it is a powerful product, it can have some problems. In this final part of our troubleshooting series, we’ll look at the error code 43 in AMD Radeon GPU on Windows 10.

What is Causing the AMD Radeon GPU Error Code 43

Incorrect driver installation: one of the most common causes that can lead to this problem is an incorrect switch from generic drivers to specialized counterparts. In this case, you can solve the problem by running the hardware and device troubleshooter and applying the recommended solution.

AMD driver is out of date: Note that some AMD GPUs (especially older models) are not updated via Adrenaline. Instead, Windows Update performs this task. If this scenario applies and you are actively blocking the installation of new updates on Windows 10, you can solve the problem by installing all pending Windows updates (important and cumulative).

GPU driver conflict: If this problem occurs on a configuration with an integrated and discrete graphics solution, it is probably a driver conflict. This happens quite often with DELL and Lenovo computers, as they usually preload drivers. In this case, you should uninstall all installed drivers and dependencies belonging to AMD before reinstalling the latest versions through the official channels.

Faulty motherboard driver: as confirmed by several affected users, this problem can also occur due to a severely outdated motherboard firmware driver that is not compatible with Windows 10. If so, you may be able to solve the problem by installing the latest BIOS firmware available for your motherboard.

Damaged system file: In some cases, this problem may be due to a corrupted system file that affects your operating system. If this is the case, you may be able to solve the problem by using a procedure such as a clean install or a restore installation to return all Windows components to their default values.

GPU firmware not optimized for cryptocurrency mining: If you see this error code when trying to mine cryptocurrencies, you probably need to install a patch to remove the clock frequency limitation and allow higher frame rates. This is true if you have multiple GPUs and use the platform primarily for cryptocurrency mining.

Custom firmware affects standard operation: if you bought a used GPU that was previously used for cryptocurrency mining, you can expect general instability if you use it in a normal setting with one GPU for normal operation. In this case, you may be able to fix the error by reinstalling the default firmware.
