I have Gpu mining with 6 graphic cards...
6x Rx 470 8Gb.
I don't know where is the problem, also i updated the bios and with this version is required to press any key to continue ( but my pc i don't have at home ... ). This problem just wasted my time...
Just when i'm starting mining , after 2 minutes the pc automatically restarted...
I turned off Windows Firewall and Windows Update..
Also i have another problem with other computer ... my friend tried to flash ... but he make a mistake , he want all graphic card in one time to flash... Now when he try to turn on the pc ... the monitor is going to sleep and i can't see anything , he try with another monitor also he get this problem... I don't know where is the problem..
Sorry for my bad english... Hope to get help about this ...
run the rig with one card and see what happens.
one of the risers may not be good.
one of the cards may not be good.
if 1 card runs non stop no problems add 1 card extra and you are at two cards.
if two cards run good for a few hours try the third card.
keep adding a card until there is a problem.
