so i have the 4870's crossfired, but GPU-Z and amdgpuclocktool both show the primary card as pci-e 8x and the second card at pci-e 8x @ 2.0.....

sometimes they are both at 2.0 but its weird, should i be worrying about this? and if so, ho can i make sure they both run at 2.0 full time?

any help appreciated, thanks in advance

after some testing it seems the first game i launch after a fresh boot is at 8x/8x 2.0, and after quitting the first 3d app i run it drops to 8x 1.0 / 8x 2.0 .... if that helps....
