Can someone explain to me the difference with ram & its speeds. like why is a 1GB stick when it transfers at say 3.2GBps labled as 1gig. What the diffence between the speed and the advetized memoroy. why is it not labled as 3.2gig? ex: Corsair Memory VS1GB400C3 PC3200 1GB CAS3 -< this is a 1gig stick capable of 3.2GBps. also i have a old computer that im useing to play about with, it has this motherboard ASUS A8N-E Motherboard - Product details and features - DealTime It has a frontside bus of 1000mhz but only support a max ram speed of 400mhz, why is this. i thought the FSB speed was the maximum of the ram speed???
