Clock speed wrong in windows

[Dyewitness]

Hi all

I recently updated my ASUS p5w dh delux BIOS to the latest version.
When my computer posts it states that my clock speed is 3.06ghz. But in windows and cpuz. Its saying my clock speed is 2.4ghz. This only started happening when i updated my BIOS. Does anyone know what i can do to remedy this problem?
