My Goldshell Mini Doge keeps having a stroke every 2 days

You switched to 2.1.2 and it is still running strong?
Is the hash rate better than on 2.0.2 or the same.
Did you figure out the graph or is it not as good as 2.0.2? I was going to switch to 2.1.2 tonight but wanted to check first. Thanks for the info?
