PCI-E 2.0 being reported as PCI-E 1.1 in GPU-Z

post #1 of 5
Thread Starter 
As you can see in my sig, my motherboard is a P8Z68-V Pro. It has 2 PCI-E 2.0 x16 slots but GPU-Z is reporting the bus interface as PCI-E 1.1 x16. What's the deal?

Are they under load and if not, does it still report that when they are?

Go to gpu-z then press the question sign (?) Then proceed to do a render test,at the bottom ((lefthand) you will see your true bus interface,if it still says 1.1 then you need to access your bios and set accordingly....note it will always if im not mistaken say 1.1 when not being fully utilize I.e gaming/render testing....

Ah, I guess it's only when the card is idle. Under load it does report as 2.0. I never knew PCI-E had that sort of power management system. Thanks guys
