I am just wondering, is it possible to overclock an AMD64 3700+ S754?

I am currently using an Asus K8N-E, with 1 Corsair PC3200 CL2.5 and 1 Corsair PC3200 CL2. Board is running at DDR333. PSU is Enermax 460W FMA.

1. Is the CPU multiplier unlocked?
2. What does it mean by DDR333? What I know is it runs at the same cpu speed??
3. Even if its a minor overclock, can I say, overclock the ram, but with a lower
multiplier, achieving result of around 2.4ghz as well? Does that increase
performance?
4. I might want to upgrade to 2GB memory, what kind of rams are good for an average
OCer (I know this cpu cant o/c much), and what's the average price for these rams?


Thanks in advance, sorry for the noobish questions. Its been awhile since I've used AMD, and that was a 1.4ghz Tbird.

Thanks for the reply. Well, I'm at work at the moment, see, it says DDR333 when I use my different corsairs together (in cpu-z it says PC2700 & PC3200). Motherboard is Asus K8N. Anyway I remember at CPU-Z at standard settings, the rams are running at 166Mhz. I managed to overclock the FSB to 220Mhz and get a speed of 2.64Ghz. Primed it about 2 hrs, and played CS a bit. Seems to run ok. What's bugging me is that the memory speed is at 17XMhz?
