I have a evga 1600w G2.
My OC:
Core 1200
Memory 2150
Voltage -50 in msi AB
I uninstall driver with ddu, and reinstall driver 19.9.1 to try.
You can always easily diagnose the problem by running the cards ALL STOCK
- Lowering your gpu clock to stock or lower
- Lowering your memory clock to stock or lower
- applying default voltage.
If they still hangup, start removing one card at a time.
If you still have problems, it may be a driver/software problem
