I think im rather confused here. I know that my current CPU (2400+ Tbred) FSB is 266mhz. So inorder to make the most use of it, i have to have ram and a mother board that can handle at least 266mhz. And if i had say a new barton cpu i would need one that could handle 400mhz fsb.

Now i have seen mobo's and ram that can do 400mhz and more. But the new Athlon 64 chips for instance are listed as have a FSB of 1600mhz... and the p4 is 800mhz. So is the FSB of these chips realy double the XP's? I mean i know the 64's kick ass but 1600mhz fsb??? thats nuts...Even DDR2 ram is only what 533mhz? 600something maybe? so am i realy that out of the loop or am I missing something?

The Athlon 64s have the External FSB integrated into the CPU core and it runs at the CPU core speed and is 128 bits wide. The 800/1600 and 1000/2000 FSB ratings you often see on Athlon 64s are the ratings for the Hyper-Transport I/O connection that connects the CPU to the Chipset and runs a 16-bit by 16-bit bidirectional interface at 800MHz (1600MHz effective) on Socket 754 chips, and 1000MHz (2000MHz effective) on Socket 939 chips.

The problem with intel is that the multi for the fsb is 4x, but in reality the P4's dont run as fast as they say that they do
