Asrock h97m pro4 crossfire

Hi I have an Asrock h97m pro 4 http://www.asrock.com/mb/intel/H97M%20Pro4/index.asp?cat=, I was wondering if I ran crossfire on this board will it run in the slower x4 mode? Thanks!

Total bandwidth is x16. Two GPS's would share that and there would not be much difference if the two slots were running at x8 together. Even the higher end GPU's are not able to come close to using up the bandwidth.

Just for clarification, even if I have 2 graphics cards plugged in it wont drop down to x4? Cause on asrocks site it says
- 1 x PCI Express 3.0 x16 Slot (PCIE1: x16 mode)
- 1 x PCI Express 2.0 x16 Slot (PCIE2: x4 mode)
- 2 x PCI Slots
- Supports AMD Quad CrossFireX™ and CrossFireX™"

The max will be x4 with the second PCIe slot. In tests there is hardly any difference at all between 2 slots x16 & x8 versus 2 slots x16 & x4.
