Motherboard cannot correctly recognize CPU

My computer has ASUS Striker Extreme Motherboard and QX9650. My motherboard cannot get the full advantage of the sheer power of my CPU. So upon start-up, the computer state that BIOS must be updated to get the full advantage of the CPU.
However, when I updated (ASUS update utility) it states that there is no update to the BIOS available. Hence, the CPU runs 2.0GHz instead 3.0GHz. How can I renovate this problem?
