Seems like the 6pin powered risers didn't solve the issue. Rig did work stable for longest period now, think it was something over 24hrs. Plugged out 1 GPU to see is 6x GPUs causing it to crash... Every GPU was on separate cable on PSU but still crashed... Out of ideas now
EDIT: Now my x4 1070 rigs are crashing too. Same shit all over again, Either GPU1/2/3/4 has stopped working bla bla, crashes the whole rig... Can anyone provide me with a solution?
Also, I've got a Gigabyte H110-D3A on those 1070 rigs, could that be the issue? Put one as a test back on AsRock to see for a test, will let ya know
EDIT2: Yep, AsRock didnt make a difference. Sometimes it crashes with a freeze
