dont forget - the IBM Part (750FX) is rated as having an external interface running at up to 200MHz (ie: extreme limit) but dont forget two other very important parts: the motherboard and the Articia-S.
I believe the Articia is only capable up to 133MHz (possibly 150 but that might be pushing it), so therefore the motherboard wont be going much faster than the chipset.
I feel the fastest FSB is therefore 150 if you are incredibly lucky, and you run it outside in winter with a fan the size of the Cornwall wind farm.
and given the trouble people have been having with Memory at 133 MHz, I'd say 150 might be a step too far.
so: 133 MHz FSB, set multiplier to 7.5 times, put an [color=0033FF]Enormous[/color][/b][/i] fan on the CPU. possibly one on the northbridge too !
other than that, good luck, hope you dont fry your long awaited A1. ;-)
apparently IBM had a bit of trouble getting FX's to run nicely at 1GHz - so they shrunk the die (and a few other tweaks) to get the GX (up to 1.4GHz ?). HyperionMP posted on another list somewhere... Ben - wanna confirm ?! :-) )
