Ethereum Mining Issue: Device Not Found, No GPU Output on Multiple Computers
As a crypto enthusiast with multiple computers, you are probably no stranger to the frustrations that come with troubleshooting in the digital realm. I recently encountered a similar issue on three identical computers: Windows 7, Windows 8, and an older x64-based Windows 10 system. My goal is to share my findings, possible causes, and solutions to this issue affecting Ethereum mining.
Problem
My setup consisted of two 7700HD ATI graphics cards (one in a separate case from the third XFX HDI 7870) and an x64-based Windows 10 system. All hardware was optimized for Ethereum mining using AMD Radeon software. At first everything seemed to be running smoothly, but after some time of idling, I noticed that my Ethereum mining process had stopped and there was no GPU output on my computers.
Device Not Found Error
After some research, I discovered that my operating systems were reporting a “Device Not Found” error when trying to launch AMD Radeon software. This error message usually indicates that the system was unable to find one or more devices with the specified drivers installed.
GPU Output Issue
The final issue was that despite using multiple graphics cards for Ethereum mining, no output was visible on any of my computers. The Radeon software was still properly installed and configured, but I was not seeing any GPU activity.
Possible Causes and Solutions
- Hardware Configuration: While all three systems were set to use the x64 architecture, the AMD Radeon Graphics drivers may have a version conflict or incorrect settings that are incompatible with Ethereum mining.
- Driver Issues: Outdated or corrupted graphics drivers can cause system instability, including the inability to properly launch Radeon software and display GPU activity on all devices.
- Network Connection
: The temporary issue may be related to network connection issues or interference from other devices.
Possible Solutions
To resolve these issues:
- Update Graphics Drivers: Ensure that your graphics drivers are up to date by following these steps:
- Windows 10: Open Device Manager (press Win + X > Devices and Sounds > Device Manager), expand Display Adapters to find your graphics card, right-click it, and select Properties. Click the Driver tab and click Update Driver.
- On older systems or computers that do not have Windows: Refer to the manufacturer’s documentation for driver updates.
- Disable AMD Radeon Software: Try disabling AMD Radeon Software to avoid conflicts:
- Windows 7: Open Radeon Software, right-click it, and select Properties. Uncheck the box next to Run, and click OK.
- Windows 8: Press Win + R, type “radeoncfg.exe,” and press Enter. Right-click your graphics card in the list of available devices, and select Disable Device.
- Network Settings: Verify that your system’s network settings are correct:
- Make sure you have a stable Internet connection.
- Check that other devices are not interfering with your Ethernet or Wi-Fi connections.
Conclusion
This issue affected all three computers, resulting in a “Device Not Found” error and no GPU output in the Ethereum mining setup. By identifying possible hardware conflicts, driver issues, and network connectivity issues, you can take steps to resolve these issues and ensure that your Ethereum mining operation runs smoothly.
