I overclocked my gtx 1080 ti fe to 110 power limit +110 core clock and +55 memory clock. It mines Zcash at 730 Sol/s at a temperature of 64 degrees with fan at full speed. anyone knows how far i can overclock it without getting unstable?

I'm pretty new to cryptocurrency mining and I was wondering what currency i should mine and how to do it. I have a gtx 1080 ti fe and want to mine when I'm not using my pc (at night and when I'm not at home).
help is welcome.
