Memory questions for P4

Sorry if this question is too basic. I haven't kept track of technology related to P4 for a long time. I'm still using P3 and they work fine so no need to upgrade. I just want to know how the memory speed is matched up with CPUs. I see most P4 CPU support 800Mhz FSB and people use PC3200 at 400Mhz to match up with it but how do you come up with the CPU's speed because I see people change certain # to overclock their CPUs. If someone can give me a quick explanation of this or a turorial link, that would be great. Also, what' difference with DDR2? It just double the speed by letting you run in dual-channel mode?

Oh, with P3, I remember I can overclock by changing the multiplier in my Abit BIOS setup. If I use PC133, the BIOS will pickup default multiplier and list a couple more for me to choose. Rated CPU speed = 133 x multiplier. How do people over clock their P4 nowadays?

You remember incorrectly, unless you used an "Engineering Sample". All the other P3's had their multipliers locked.
But you could have changed the Front Side Bus and OC'd the P3. 😉
