Ok..I have itchy fingers with an Overclocking Question ?

Just need to know something

Asus Mobo with 2500 Barton
When I very 1st booted up the pc it went straight into Bios and one of the 1st things I did was set the CPU speed to 1800 out of a list from 1100 through to 2200.
What I need to know?? what would happen if I set it to 2200 from 1800.
Here is an CPU-z of my present config.
