Having trouble mining when you use both an AMD graphics card and an Nvidia card together on the same computer?
Having trouble mining when you use both an AMD graphics card and an Nvidia card together on the same computer?
Hey, here is my PC setup: Ryzen 5 3600x, AMD 6700XT Hellhound paired with an RTX 3060 on an Asus B550 Tuf Gaming Plus board. I used DDR memory from Corsair Vengeance and a large SSD like ADATA XPG SX8200 PRO for storage. Everything else is also included in the build. When I try to mine using both cards, the Nvidia card only works at half speed. Even though I installed old drivers 470.05_gameready_win10-dch_64bit that were working fine before. I can mine full speed when just one card is used, but when I use two cards together there is no problem. I tried uninstalling and reinstalling all the drivers using DDU v18.0.3.9 to start fresh. Even after doing this nothing changed. Maybe it's a compatibility issue between AMD and Nvidia? Any help would be great! Thanks
Check how well your CPU and GPU run by looking at Task Manager. Look at two special tabs: Processes and Performance. What matters is seeing what changes when you switch from old single GPUs (like the 6700 XT) to a mix of different ones, which often means lower speed. Make sure to download the right drivers directly from the company's website yourself. If needed, reinstall or adjust your settings. Don't use any extra software tools just for this.
Use Resource Monitor to watch how well the system runs while using different GPU setups from your old post. Check if there are big differences between the "no problems" rate on those 2 x 6700XT cards, how it looks when you run just one card at a time, and how both cards work together.
PSU: Tell me about the power supply - make, model, wattage, age, condition? Was it used for heavy gaming before or mining? Skip DDU. Download drivers manually from the manufacturer's page. Then reinstall them and set up your PC again.
Do you have access to another working power supply unit that you could swap in? Even if it looks okay on the outside, the inside might not be right. If you know how to use a multimeter or know someone who can help, you can check things out. That link shows how to test one manually, but it's not a full load test. Still, any voltages that are too high or off are concerning. Your PSU might work fine with just one card, but two could get overloaded and damage the unit over time.
Check your CPU and GPU performance using Task Manager. Look at two specific tabs called Processes and Performance. You need to see how much hashrate changes when you switch from the original 6700 XT GPUs to a mix of different cards instead. Remember: make sure you download the correct drivers from the manufacturer's site, install them all again, and set everything up correctly on your build. Do not use any third-party software or installers.
It might happen. You can check again using Process Explorer from Microsoft, which is free. Visit this link for details: https://docs.microsoft.com/en-us/sysinte...s-explorer. Sometimes you'll need to try different graphics card settings to find why certain programs stop working or clash with each other. It could take a while and lots of work to figure out the real cause of the issue, but once found, it helps explain what's going wrong.
