Am having an issue when connecting more than 1 AM 290 card.
Its a Sapphire 290. Both cards are exactly alike.
I am using CGminer 3.7.2 with -I 18.
8 gig of memory
120 gig SSD
Windows 7 fully patched
Two power supplies .
950 Watt to Card 1 and MotherBoard (ASRock Z87) it has slot for 5 cards.
950 Watt to Card 2.
each card is inserted into the PCIE slot no riser.
each card works fine by itself and gets around 730 Kh/s.
when I connect the second card, and start CGminer, it runs for about 5 sec and then crash.
Any Ideas?
Thanks in advance.
