Hello all,

Slipped with a screwdriver and now am back to using my old DFI. It has a 790FX NB but only the 600SB. This MB has run 3 hard v mod 3870's and later 4770's in Xfire with no problems. I have put in the 6870's but ccc tells me I need to hook up both bridges. This will be a problem as there is only one connector. I have tried using each card one at a time and no problems. Both score about the same in tests. It does not matter which display port I use. I have half a dozen bridges and tried 4 of them, no good.

Also ccc shows one card as disabled. MSI Afterburner shows both cards but zero activity (mem,gpu use) on one card.

Any ideas? I never ran the cards in Xfire on the new board so I do not know if they work. As they each work by themselves, I think the MB is the problem.

All drivers up to date, clean install etc.

Thanx for any help.
