Alright, update to my mobo issue.. Got the asrock h110 pro btc+ today and wow.. wish I would have ordered this board originally, it was practically plug and play. Had absolutely 0 issues plugging in all of my 1080ti's and the performance seems slightly better (5-15 Sols/s) on this mobo more than the original MSI board I had, which is awesome. Thanks for the recommendation, super impressed and it was a lot cheaper than the board I had originally.
From experience motherboards hit and miss. I tried h110 pro and even the popular Asus Z270 Prime wasn't good start. Whats funny my other rig has the same model as yours started good. So I got H110 Pro replacement and it was much better until 2 months that I ask for another replacement. Finally decided to sell it to my friend because he would be long time miner. You can't really resell this to other people who only games.
Asus Z270 prime isn't bad just I got unlucky like the H110 but I didn't instantly avoid or feel regrets like many people do with products.
I'm still using MSI and Asus motherboards to this day.
