I didn't test that motherboard because I always bought socket 775 motherboards that could support C2Q; the 3 that I still have all support C2Q processors.
In the first link, the reply is incorrect because he failed to check the "Since BIOS Version" column like I did. Buy a C2Q if you trust the totally wrong info in the second link. Rely on what the manufacturer says, not on some untrusted info. If you really want a C2Q, then buy a used motherboard that supports it. If I were you I would build a better system.
