Is it possible my crossfire bridge is just broken?
so, I have had many issues just trying to crossfire, but I remeber that I read somewhere that if your gpu is being read as x8 the bridge is broken
so I installed gpu-z and it says both of my cards are running at x8 1.1 in pci-e 3.0 slots
from my understanding it shouldn't be doing this if the crossfire bridge is connected properly, so in other words, nothing is wrong with the software or my gpu's its just the bridge

I would like clarification on this before I go out and buy 2 bridges or send in my gpus for rma (i talked to sapphire, they said my brand of card requires 2 as I have 2 connected)
(before you ask, yes my cards are crossfire compatible, they are the exact same card)

The cards are going to run at x8 depending on the motherboard and the processor (depends on how many PCI-E lanes you have). It's fine, as long as Crossfire is working. x8 at PCI-E 2.0 or 3.0 usually only sees a ~5% performance difference from x16.

Click the question mark next to where it shows you your Bus Interface and it should read as PCI-E 3.0 after you start the render test.

What is your motherboard and processor?
