Can you overclock nvidia cards on simplemining?
yeap
What cards are you overclocking and do you have any troubleshooting tips?
I am using over 100 GTX1060's in multiple rigs and overclocking working perfectly.
Suggest you try using an SSD if you are using a usb stick and slow usb sticks can also cause overclocking issues.
If the ssd does not solve the problem delete your rig and reboot your rig and setup new overclocking settings.
