Confusion about my MoBo's RAM capacity

Hello all,

I'm am currently trying to understand the whole FSB and what your RAM speed should be. i.e. PC3200 and so fourth.

Here is a my confusion.

I had my computer bulit locally by somone in town. The mobo is a nForce680i SLI. The box for the mobo says it takes DDR2 800 RAM. I would assume that this would mean I would put PC3200 RAM in? (800 x 4 = 3200, because intel multiples the FSB of 800 by 4, correct?)

Ok, I went to and scanned my computer and it says the guy installed 2gb PC6400 in the computer? Should he have put PC3200 in?

Also the review for my mobo says that the FSB is 1066/1333Mhz? But the box says DDR2 800!! Doesn't that mean 800Mhz FSB?

Any help on the confusion would be great! Thanks!

Ok, I've found this article
and it says that DDR200 is PC26400, the memory Crucial recommended.

I'm still confused though because the artciles says a DDR200 PC26400 has a FSB of 200Mhz? How can this be, the review of my mobo shows that I have a 1066/1333Mhz FSB?

This table would also be helpful for today's modern motherboards and cpus.
