WOW 2% valid! lol best pool is worst pool.
Where did you get this statistic
From my dashboard share information. It is for my rigs
Maybe the problem is somewhere in your settings.
Try new port 3315.
Varidiff isn't helping, I had 40% when I was originally on there. Also kills my hash down to half
I don't have this problem anywhere else, only settings are pool/worker and frequency which is at factory setting
