So I just got my hands on a Dell XPS 720. I did install a Core 2 Quad Q9550, but the computer detects it as an unknown CPU and does not have all the features it should have, like enabling VT-x. The CPU is a Core 2 Quad Q9550 spec SLB8V. Attached is the original BIOS. I think it needs the newer microcode to work better. It will boot, but the computer doesn't exactly know what the CPU is.
