hey guys i just recently bought a crossfire setup (2 6950's) and was reading that the lane speeds of the Pci interfaces differ i loaded up GPUz and saw that the first card is running at 16x and the second card is running at 4x, now i heard that 8x by 8x performs better than 16x & 4x.
so i want to try this out and run both cards at 8x to see if there actually is any difference in performance.........
but i have no idea how to get both cards to run at 8x and was wondering if i maybe put the one card in the wrong slot as there are 3 on the motherboard.
so here are some pics of my setup
now the only thing that is worrying me is moving my bottom card up to the white slot, the cards will be right on-top of each other with the bottom card blocking the tops airflow??
also i was wondering if its not better to just leave the cards at 16x, and 4x for games that don't support crossfire logic being that the main card will have better performance for these games as its sitting at 16x? this make sense? or do you guys think i am just nitpicking and the performance gain will be negligible?
