It really depends on your RAM. If it's overclocking-friendly, you can go higher than 200. But I have no idea what type of ram you've got so bump it up higher than what you have set at right now. Who knows? you might still be using PC100 on a KT133A chipset motherboard. I don't even know whether your cpu is type A or B. What motherboard? Do you have a quality PSU? do you see where I'm going at? More info. you provide will get responses quicker. And check other threads. This forum is plastered with 2100+/1700+ overclocking threads.
