AMD Athlon 2500+

I bought a swiftech heatsink that is really nice, and feel comfortable with overclocking now.What are the steps I should take? I have an A7N8X DELUXE motherboard that supports up to 400mhz bus. As of now with the jumper setting it only has the option to go 200.

I know that upping the FSB means I should also up the RAM right? If so...how and to what.

Thanks.

By what terms do you refer to operating frequencies for ddr RAM? I want to know.
