solved it?
lol he hasn't been active on the forum since December.
I think the main reason that he can't solve the problem is a lack of driver support for the 7950GX2 card. To the OP - are you running Vista or a 64-bit OS? Perhaps one of the peripheral PCI-E power connectors isn't fitted in all the way, or even further and highly overlooked - do you have any dust in your case? Perhaps it's preventing airflow to the channel between the two 7900 cards (after all they are sandwiched together).
