Pci-e lane fail?

post #1 of 39
Thread Starter 
A while ago i decided to set my video card into the second pci-e slot, but found that it was limited to 4x. I moved it back to its its original position in the first slot, where it was running at 16x before

It is now running at 8x in the original slot. Why?
There is no second card of any kind in any other slot at all.

Are you using any of the PCI-E x1 slots or anything that's USB 3.0?

I'd say it's not the motherboard. But you can't know for sure til you reinstall the drivers and see
