I have two HD5970 installed in a P6T SE motherboard in the two blue (x16) pcie slots and 2 out of 4 gpu's appears to be running at x8 speed given the information taken from ATI ccc and EVEREST ULTIMATE. I have the latest drivers (windows 7 64/ATI catalyst 10.2) and no RAID configuration (if that matters). I also have an i7 975 (stock speed). A single vga card also runs in both gpu's at x8 speed (installed in the first pcie x16 blue slot) instead of x16 speed. Is there a BIOS setting i need to change or something else?Any help would be appriciated.
