Chipset supports processor but motherboard does not!!!

Hello guys how are you? I currently have a motherboard on who's specification site it does not list anywhere that it supports Core 2 Quad, but i have intel g31 express chipset family and on intel spec sheet it list that it supports core 2 quad so right now i am stuck and can't decide whether or not my motherboard supports the core 2 quad. And if my motherboard does not support it can anybody tell me why it doesn't support. Thanks in advance. By the way my motherboard is Lenovo 9481D6U.
