Im having is an unusual number of stale and invalid shares that seem to be comming from my 1080ti's. The temperatures are ok. I dont know what miniZ's configuration is for them as its automated but i need to try to solve this sissue. I've used a pool ping tool and i have an excellent ping from here in the UK to the German pool so its got to be the miner configuration or the driver. Miniz is also showing 99.5% success rate for shares on both 1080ti's. Im trying to figure out whether its because i'm undervolting the card significantly but i'm doing that on 1 card so i dont see why i'd be getting the same lower shares on the other card. One possibility is the driver - im having to use 470.05 to allow  2x 3060s to run together. I'm not 100% certain how this is affecting the other cards... The 2070 supers run fine with 100% share success but the 1080ti's do not...
