I upgraded to 7.2b so I could use newer graphic drivers as memory tweak started to make some errors and I tried to fix that.
I have 3x Vega 64 water cooled in W10 in this PC.
Memory tweak is working now but after graphic driver installation and crossfire disabling the first and second gpus are mining 44.5 mhs and not over 50 as before for a long time. 3. gpu is working as before and the share count for gpus show that they are mining at different speeds.

I think this is a driver or W10 issue but I can't find what is wrong and all settings in AMD driver program are same for all gpus, any ideas?

What kind of page is phoenixminer.org virus or mallware?
