The mobo asks the CPU for the information to set up the timings. Just like it asks the memory for it's timings. I have not seen a way to overclock EFI yet, so you have to hope someone could so it in software (on the OS X side).I was just thinking the same thing, and ended up here searching for some answers. If you can't overclock a mac fsb through software/bios in any way, it must be because the fsb is set from factory and cant be changed?
so if that is the case, it should work in theory to put a cpu with 1066 mhz fsb and get it to run in 1333 mhz. If the fsb isnt controlled by the cpu? would be intrersting to hear from someone who tried it
but im afraid Transeau's right.
That is odd, I thought the Xeons were of the Core 2 line. If they are not, what line are they from?
What kills me is how everyone here thinks that one processor of a speed is really different from another of a speed. All CPU makers do part binning. Two dies from the same wafer could run at two different speeds. Intel has been known to sell a faster part as a slower part to make up for margins. In Intels Extreme CPU's the processor multiplier is unlocked. Which basically means you can raise the multiplier higher than the stock level (you can always lower multipliers even on locked CPU's). Intel's stuff can run much faster than what they sell it for, all you have to do is wait for AMD to announce a faster part and see Intel ratchet up their CPU speed in lock step.
