hello
i have a big problem with the last version and all over miners. works with 3 cards and when i want to put 4 gpu cards on my rig, it crashes...
all the same cards, Under win10 fresh installed, AMD driver 17.4.4, stock cards, psu 1200w seasonic prime on asrock H81 rev2

risers are ok because:
- gpu 1+2+3 => ok
- gpu 1+2+4 => ok
- gpu 1+2+3+4 => ko...

claymore start well and detect the 4 gpu's but crashed before to start mining, just after GPU detect.

please help me !!
