Dude, you've been asking over, and over, and over, and over, and over again while ignoring most advice given to you. Take a step back and listen to what others have to say before trying things randomly without actually knowing what you're doing.
First off, uninstall Furmark. It's useless and only stresses your card for no reason. Test for stability with games (The harder they are to run, the better. Witcher 3, I've found, is the best for that)
Secondly, undo any overclocking (Just press the reset button in Afterburner or whatever) and disable any overclocking software (don't let them run at boot), then reboot and run The Stilt's VID app
and post what it reports as your DPM7 voltage (Or even better, post a screenshot of it). If we don't know that, any offset you apply is useless, really.
Third, install GPU-z and give us your VRM temps and actual VDDC under load. You could also have it record everything (In the bottom of the sensors tab - also have it refresh the sensors every second instead of 2.5s or so that it is by default) and then zip and upload the log here so we can see what's going on. Or, again, even better would be to post screenshots.
I'm willing to bet your card is a low DPM7 one and you just need a bigger offset. But you can't just try random things and expect it to work. Help us help you.
