thats right

Yeah but hyper transport is just the stupid AMD way of saying FSB but it does do some other things as well but we dont need to worry about them if you do wanna read about it just read the wikipedia article here
http://en.wikipedia.org/wiki/HyperTransport its a lot more complicated than just the FSB but that i sone of the things it does

As for the memory on the Amd chips thats calculated by
Cpu speed divided by the FSB: Dram so if you have a FSB: Dram of cpu/6 like me with an athlon X2 4000=(2100mhz)
You get
2100 Divide by 6 = 350 , so my ram only uns at 350mhz ddr so in all 700mhz rather than 800mhz
To get the Ram back up to 800 in theory i would have to OC to 2.4Ghz i think
cos like 400 times 6 = 2400
