Issue

I have a Rampage IV and I just noticed my setup is running 16/8 instead of 16/16. I know it was running correctly before but I have upgraded my bios since then, I am thinking this is when it changed? But I am not sure to be honest. BIOS reports 16/8 as does GPUZ w/fullscreen. Cards are in the proper slots for 16/16 I do have my sound card in x1 slot. Can this be bridge related? BIOS is also set for GEN3 but I also tried GEN2 and same result. Running most current bios from asus.com 4804. I have a soundcard installed in PCIE 1x slot, that should not cause this correct?
