ok, i just put my 7800 into the bottom PCI-E slot. the jumpers are on Normal. Do i have to switch them or will both slots run at 16x? My chipset is not SLi
if you have SLI, either both slots will run at 8X, or one will run at 16X and one will run at 2X, unless you have a certain board which supports 16X for both slots, although that doesn't really make much of a difference
having it at 8X/8X is recommended over 16X/2X
ok, well i couldn't get those jumpers out because i have big fingers . but i put it back into the top slot and its reading at 16x. but why is it recommended at 8x/8x?? do i get better performance at 16x?
