Asus Maximus VII hero Mooded bios

[Tymoteo]

Hi I need a modded bios to allow access for advanced video card settings I need to manually set video cards to work in PCI-E x4.... is this even possible??

I plug 3 video cards but only card 1 & 3 are detected in windows, card 2 is by default set in bios to PCIe x0 and card one is x8 I need a way to change this...

I'm new to all this sorry if I didn't post in right place.

any help will be appreciated...THX
