please advice me. Now almost all vendor in my country cut off warranty if I flash bios so I have been use claymore with strap for a long time. after he look like stop update I start to try mining with pheonix miner but got a probelm.

I try -mt option. My asus 570 8gb (not flash bios) with mt 0 got 25MH, 4.0MH with -mt 1 and crash with -mt 2.

What am I done wrong? please advice me. I use latest amd driver.
