multiplier vs fsb

PEople say it's hard to overclock the 2.2a because it has such a high multiplier. What's the difference? Shouldn't it be easier to overclock with a higher multiplier then massively increasing your fsb? Even if you increase your fsb, you still have to eventually set dividers, so why do people like lower multipliers and not higher multipliers? I just don't understand.

It's harder to overclock a 2.2A cause that particular chip is already close to the limit it was designed to do. The die used in the A series Northwoods maxes out at 2.4 in production. The same die design is used from the 1.6A's to the 2.4A's and when you go with a slower production chip speed to overclock in the series it tends to have more overhead for overclocking then a higher production speed chip in the series.

Yeah, and people like to push the fsb as far as they can WITHOUT enableing dividers. It overclocks everything. A [email protected] will outperform a 2.2A unoverclocked. Why? Increased memory bandwidth and overclocked pci cards and video card.
