Just FYI:  I got my new risers in today and that fixed this problem.

Boozer do you use powered risers for all the cards? Just wondering if I would need to get powered risers for the 16x16 risers in a 4 x 7970 rig or just the 1 x 16

Also can not having enough power from running unpowered adapters cause the machine to crash after being able to run for 10+ hours?

thannks

I too am wondering this.

I cannot seem to be able to run 4 cards for more than ~6 hours at a time.

I am now running 2 cards for ~9 hours. I'm keeping my fingers crossed that they will go indefinitely.

The only thing I haven't tried is powered risers. I'm looking to create two of these today on my 1x risers where I'll add 1 card at a time with the new powered risers.
