Does it work well? Voltage is the most important thing, it must work.
Twelve hours mining ETC and it hasn't changed. Only problem as I mentioned in my first post is that closing Claymore and starting it again raises voltages - I set 980mv (shows 963mv in HWiNFO64) but changes to 1044mv when I restart Claymore. Then again my Strix has 1150mv factory voltage @1310MHz

It's terrible, watttool has current scale and that helped a lot on making the cards not throttling, anyway you put regardless if using afterburner or ccmanager the card throttles if you change the clock. So a tool like wattool would be great, current scale is important.
The problem about the current driver is that it only accepts the default clocks, so if you change the clock to more than what is on bios then the voltage will increase very high, from 0.95 to 1.14, so in simple terms, from 110 watts to 160 watts, for example, if you have 2 cards with set frequency 1100 and you change to 1101 then the voltage goes very high, it does not accept a higher clock than what is set in the bios of the card.
Plus, regardless of anything you do, increasing or decreasing the voltage, the card always throttle.
