Wrong memory bus read on 2nd amd 7770

[earvinarp]

Hello,
I installed the second gpu via crossfire. It all seems fine but gpu-z shows the new gpu at 32 bit memory bus instead of 128. Is this a bad read by gpu-z or am I doing something wrong here?
My mobo is a p8z77-v deluxe.
Thank you

Interestingly enough this problem seemed to take care of itself. Now the read in GPU-Z is correct. So, that is solved.
