i have an amd athlon 64 3400+ and it says the fsb is 1600 mhz. is the fsb truly that fast? is there any ram that can even run at that frequency? i'm confused because i've been told that my fsb/mem ratio should be 1:1 on an athlon system, but how can that be possible if the fsb is 1600 mhz and (at least i dont think i can) get any ram that runs that fast. my mother board is capable of running at 1600 fsb but whats the point? any info you could provide would be much appreciated.
