msallak1,
Just a bit of warning from my personal experience - I killed one card and damaged 3, 1080ti, with too much overclocking. Don`t push them. I overclocked too much and they lasted just 18 hours, then died

WOW I just restored default settings, I think the extra 40 hashes doesn't deserve the risk!!! .
I will stick to stock clocks then and hope will reach ROI
