CPU FSB Wall?

When overclocking, usually FSB would be what the motherboard can handle. But recently, I have been hearing about CPUs having it's own FSB limits per multiplier, is this true? I always just thought that the overall speed (say 3.6GHz for the e6400) would be the limit and not the FSB per Multiplier on the CPU.

Anyone do any experiments to test this out?
 
generally, CPUs do have a limit to their overclocking ability due to their manufacturing processing differences in batches. temperatures of the CPU and the motherboard/NB have an affect on highest FSB achievable, and there's more reasons for "walls".
the E6400 can achieve anything on proper cooling. On air, I can hit 3.733 and there have been close to 100% OC's on water and phase. (XS Record DB puts the highest E6400 OC at around. 4.1-4.2GHz).
What you may be confusing is that "F" batches generally do not OC as well as other A and B batches because of the manufacturing processing differences.
