Using PCI-E 3.0 port without Ivy Bridge

I am trying to use crossfire on my MB, it is a Biostar TZ77B. It has one PCI-E 2.0 slot, which is fine with my i5-2500k processor, and it also has one PCI-E 3.0 port. From what i hear i need an ivy bridge to even use this port? yes or no? and if yes, can i make it able to be used without buying the ivy bridge? Thanks

  1. No, you don't need an IB CPU to use that port. It will just act as an older port through backward compatibility.
  2. So i can crossfire 2 AMD 6870's via the PCI-E 2.0 and 3.0 ports without breking the wallet to buy an ivy bridge?
  3. Yes.
  4. Thank you for the help, i have been contemplating this for a long while lol

    It won't be PCIe 3.0 without an Ivy CPU, but yes, you can still use it. It will just be restricted to PCIe 2.0 speed.
