Ethereum: Device not found. NO GPU output 3 Computers same issue?
Ethereum Mining Issue: Device Not Found, No GPU Output on Multiple Computers
As a cryptocurrency enthusiast with multiple computers to mine, you are probably no stranger to the frustration that comes with troubleshooting issues in the digital realm. Recently, I 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, potential causes, and solutions to this issue, which is affecting Ethereum mining.
The Issue
My setup consisted of two ATI 7700HD graphics cards (one in a separate enclosure from the third XFX HDI 7870) and an x64-based Windows 10 system. The hardware was fully optimized for Ethereum mining using AMD’s Radeon software. At first everything seemed to be working fine, but after some time of inactivity I noticed that my Ethereum mining process had stopped, leaving no GPU output on the computers.
Device Not Found Error
Upon further investigation I discovered that my operating systems were reporting a “Device Not Found” error when trying to launch the AMD Radeon Software. This error message usually indicates that the system is 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, the output was not visible on any of my computers. The Radeon Software was still installing and configuring properly, but I could not see any GPU activity.
Potential Causes and Solutions
- Hardware Configuration: Although all three systems were configured to use the x64 architecture, the AMD Radeon graphics drivers may have a version conflict or incorrect settings that are not compatible 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- Driver Issues: Outdated or corrupted graphics drivers can cause system instability, including the inability to properly launch Radeon Software and display GPU activity on all devices.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 Connectivity: A temporary issue may be related to network connectivity issues or interference from other devices.
Potential Solutions
To resolve these issues:
- Update Graphics Drivers: Make sure your graphics drivers are up to date by following these steps:
- On Windows 10: Open Device Manager (press Win + X > Devices and Sounds > Device Manager), expand “Display adapters” to find your graphics card, right-click on it and select “Properties”. Click the “Driver” tab and click “Update Driver”.
- On older systems or non-Windows computers: Check the manufacturer’s documentation to update the drivers.
- Disable AMD Radeon Software
: Try disabling AMD Radeon Software to rule out any conflicts:
- On Windows 7: Open Radeon Software, right-click on it and select “Properties”. Uncheck the box next to “Launch” and click “OK”.
- Windows 8: Press Win + R, type “radeoncfg.exe” and press Enter. Right-click on your graphics card in the list of available devices and select “Disable device”.
- Network Settings: Check if your system’s network settings are correct:
- Make sure you have a stable internet connection.
- Check if other devices are interfering with your Ethernet or Wi-Fi connections.
Bottom Line
This issue affected all three computers, resulting in a “Device Not Found” error and no GPU output on the Ethereum mining setup. By identifying potential hardware conflicts, driver issues, and network connectivity issues, you can take steps to resolve these issues and ensure your Ethereum mining operation runs smoothly.
