Wow, that's an amazing overclock. But yes, the 3200+ is a 11*200=2.2 ghZ. If the 1800+ has the same amount of cache as a 3200+, then it's running at full 3200+ speeds.
Edit: Looked it up, an 1800+ has 256k cache while the 3200+ has 512k cache. So it's not as fast as a 3200+, but as far as clock speeds go, it is.
