I am trying to get my MSI 890FXA-GD70 to run 5 x 5870's. All the graphics cards work fine, all both the risers work fine, and all the slots are fine, as I have tested these thoroughly in different combinations.
But, when I populate all 5 slots, it takes a lot longer to boot, at least 3-4 times a long, and then when I detect the graphics cards, by running "aticonfig --odgt --adapter=all" it get errors on 2 of the cards.
Additional Info that might be of help...
Ubuntu 11.04 64bit
Sempron 140 CPU
2 x 850W XFX PSU's
I have searched the forums, but it just seams to be people saying that what rig they want, not what they actually have
