http://service.futuremark.com/compare?pcm05=694227 it shows FSB is 166MHz but on Dell.com the M1210 is listed as 667MHz. Whats the deal? I don't get what FSB speed does anyway, just wondering if i'm missing something.

The actual FSB speed is 166Mhz, but it is quad pumped, meaning it sends four pieces of data per clock cycle, so it effectively works at a speed of 667Mhz, that is why it is quoted at that speed. The FSB is the link between the processor and the rest of the system, RAM, PCI Express, etc.

667MHz would be the core speed of the processor or CPU. 166MHz FSB (front side bus) is the speed of the bus between the ram and the CPU. Your memory is rated at 166MHz and it talks to your processor through the front side bus at that speed. The FSB is always slower than the CPU. Newer machines have faster FSB's but no one has come out with one that is the speed of the processor. If you were looking to add memory you would want to know the 166 speed.
