you run 1050-1185 core at 880mv?
Can you confirm your settings with GPU-z screenshot?
HOLY SHIT you got a good card.
I guess mines low ASIC quality (66%), so I need the volts.
Here's mine
I am using 2.2.0 msi afterburner BETA 15. You have to go into config to set Unofficial Overclocking to 2.
Without it, the program limits the max difference between memory and core speeds for stability.
So set it to 2.
Open MSI after burner set it to 710.
Close it
Open MSI after burner set to 410.
Close it
Open MSI after burner set it to 200.
Repeat, etc
