Do you guys also think that it's one of the above issues? Since 3x 6990 is 6 GPU..

I'm not familiair with that. Thanks for the share.
According to someone it's because windows doesn't support more than 4 GPU (i have 6).
According to someone else it's because my mainboard doesnt have enough lanes.

As I understand it, when using 1x risers, you sometimes need to jumper two pins on the motherboard socket.

Correct in most mobos it's needed. Quick and easy to do but you need good eyes

Did you use the jumperwire on your PCI slot when using a riser?

Hello guys
I'm trying to setup a 3 x 6990 mining rig, but windows won't detect more than two.
my motherboard is a Asrock 970 Extreme 4
I have tried different riser combinations (1=> 16 powered / 16 => 16 non powered).
SDK 2.7
Catalyst 12.8 and 13.1
Win7 64
Please help..
Update,
I now have 3 cards running, but my old settings for 2 cards won't work.
I can't get thread concurrency to 8192
I can't get intensity higher than 17
What's going on? I upgraded ram to 8GB.
