Cudo Miner lets you mine cryptocurrency using the computer’s GPU. Though, there may be times when Cudo Miner is not using GPU, which can negatively impact mining. Try reinstalling the software or restarting your graphics card driver to resume efficient mining in such a situation.

Key Takeaways

  • Cudo Miner may not use the installed GPU if the display drivers are outdated, overclocking is disabled, or the computer has multiple installed GPUs. 
  • You can resolve the error by updating the display driver, enabling all coins in Cudo Miner, and turning on overclocking in the app.
  • Remember that your GPU should be legible for mining, have at least 4GB of memory, and be supported by Cudo Miner.

Why Is Cudo Miner Not Using Your GPU?

Cudo Miner may fail to utilize your GPU when you launch it for the first time on your computer. There can be multiple causes behind this; for instance,

  • Outdated or corrupt display drivers
  • Incompatible graphics card
  • Presence of bugs or glitches in the app’s files or the drivers
  • Inaccurate Cudo Miner settings 

How To Fix Cudo Miner Not Using GPU?

You can resume the GPU’s functioning on Cudo Miner by restarting the display drivers, turning on Compute mode on your GPU, and many other ways listed in this section.

Restart Cudo Miner

Close the app completely on your system. Re-open it after a few minutes and check if the GPU works fine by analyzing the ongoing mining jobs or through the app settings.

Restart Display Driver

You should restart the display driver when experiencing performance issues with your GPU. It will solve glitches and other graphics-related issues so Cudo Miner can resume using the graphics card. Besides, we applied the same troubleshooting step when the Nvidia display driver failed to start on our computer.

  1. Right-click on the “Windows” button on the “Taskbar.”

  7. Re-enable the graphics card driver after one minute.

Update Graphics Card Driver

Updating the graphics card driver brings new features and enhanced compatibility with previously unsupported programs and hardware. You can manually install an update file for the Nvidia graphics card from the official page or let your computer search for possible updates. Learn everything about updating drivers from our extensive guide.

  1. Select “Update Driver” from the graphics driver menu.

  3. The computer will scan and install the necessary updates for your graphics card driver.

Ensure Compatibility

Cudo Miner can work with most modern GPUs, with a few exceptions. For example, you can not use Intel GPU for mining, nor does Cudo Miner support it. Check the list of supported hardware to verify your graphic card’s compatibility with the app.

Inspect GPU Memory

The required GPU memory depends on the cryptocurrency you are mining. Cudo Miner recommends at least 4GB of memory for mining Ethereum, but you should get an 8GB graphics card for stabilized performance and growth of your cryptocurrency. 

Turn On Overclocking

Along with increasing the hash rate for mining, overclocking also lets you optimize the performance of your GPU and customize the settings to meet your mining requirements. Therefore, enable overclocking to ensure Cudo Miner makes full use of your GPU.

  1. Go to “Settings.”
  2. Find the “Enable Overclocking” option.
  3. Turn it on via the toggle bar.

Enable Windows Defender Exclusions

Windows Defender may sometimes flag Cudo Miner as potentially harmful, which could disrupt the mining performance and the overall functioning of the software. Enabling Windows Defender Exclusions in Cudo Miner will prevent the antivirus program from interrupting its performance.

  1. On the “Settings” page, locate the “Windows Defender Exclusion” box.
  2. Enable it from the toggle switch.
