Help in GIGABYTE GA-Z77X-UD5H-WB

[Nsync]

in the mobo GIGABYTE GA-Z77X-UD5H-WB, the third PCIe x4 there's a note that this slot is for ivy bridge
is that mean if i use sandy bridge like 2700k then i can't use it?

it only becomes pcie-3 with ive bridge cpu's, it should work as 2.0 with a sandy bridge
