GPU is in the top slot.

I tried updating GPU-Z and the MB bios and it then it reported the bus as 3.0. now it's reporting as 2.0 again.

Anyone else have this issue? Any solution?

that's fairly normal if your outside of stressing the GPU. if you hit the question mark next to the buss speed in GPU-Z it will give an explanation of whats going on and a way to put a load on your GPU to check its maximum buss speed.

while idling, mine is presently reporting as x16 1.1. but if i load the GPU it jumps back up to x16 3.0.

now, if it is reporting the lower buss version when stressing the GPU, then you may have a problem.
