None of the above

Gentlemen,
I'd be grateful for some assistance in working out whether it would be worthwhile replacing my PC RAM with higher speed cards.
I have a home made XP/Vista dual boot system with 4 x 1Gb of RAM. (Crucial 1GB DDR2 533MHz / PC2- 4200 Unbuffered Non ECC)
Since installing it I find that Vista is only capable of recognising 3.25Gb.
Well, we all make mistakes.
I am considering replacing the RAM with DDR 2 PC 2 6400 800Mhz cards.
Now, this is where I have some difficulty. (Apart from the little faux pas above). I do not understand the complex relationship between FSB speed and RAM speed. My Asus M2V mother board is described as having an FSB of 2000MT/s which I believe is more commonly expressed as 1000Mhz.
I understand that there is a point at which the memory works faster than the FSB, to put it in somewhat simplistic terms, and as such is 'wasted effort', so would 4 x DDR 2 PC 2 6400 800Mhz cards 'overtake' the FSB speed?
One more relevant(?) thing, the CPU Spec:
AMD Athlon 64 X2 4400+ (2.3 GHz) Socket AM2 Energy Efficient L2 1MB (2x512KB) cache.
Any assistance would be greatly appreciated.
Thanks
N o t a:ok:
PS: I can't remember how I decided on the spec when I built this machine, but I suspect that it came together more by good luck than good management.
