It's best that you use the same speed as your processor's FSB.
That way they are synchronized.
The 'optimal' setting will do this for you.
In 'Advanced Chipset Features', set 'CPU Interface' and 'Memory Timings' to Optimal.
You can further tweak this for even better performance, but for the most stable settings, choose optimal.
DDR is "Double Data Rate". The actuall frequency is 200mhz, but it works on both the rise and the fall of a cycle, so it's condidered 400mhz equivalent.
If you have DDR400 (PC3200) ram, then you will also get timing benefits when using it at DDR200 or DDR333 speeds. So, your money has not gone to waste.
