not the exact same board, but very similar, I suspect you'll need to do the pin shorting thing to get more than 5 working
Topic: Need help with Scrypt mining rig!! 7950 cards (Read 453 times)
BUMP
Hi, I used to only have 2 cards in my MSI Z77A GD65.
But now I got 6 cards, and I am running into trouble. I am using 2 x AX860i power supply. No power riser (I have order some on the way), just normal riser.
I am also running xubuntu. Whenever I do.
I can see that my 6 cards are listed.
Then I reboot the rig and run cgminer. The cgminer only sees 2 cards and sometime 3 cards. But never 6 cards.
What did I do wrong? Do I need power riser? Is that why?
Thank for your help.
