As the previous post pointed out, it is difficult for that motherboard to run stable at 200 MHz. But it does not rule out the CPU to be overclocked to 2.1 - 2.3 GHz.
To do that, it require a good heat sink (in air) such as SK-7 or a SLK-800U with an adjustable high CFM fan such as TT SFII. Also, the motherboard, via bios, has to provide enough level of Vcore at 1.8-1.9+ V.
Edit: After posting, just find out from your sig that you have already reached the CPU overclocking as I pointed out.
