theres something else that confused me.

remember the old board i always mentioned that only did 1825 max dc stable?
its one of the first retail p5k3... well now it does 1900+...
i switched the cpu and wham, suddenly it runs much better.

the weird thing is, before it was running with a 6600 that could run a high fsb.
now its running a 6750... im sure i checked the fsb stability of the 6600 by using the same fsb or higher with a different mem divider. and it was stable... so i assumed that fsb was stable... but for some reason the 6600 was not stable at the same fsb when i used the 1:2 mem divider.

and the difference between the dividers must be huge, because with the other divider i could run an fsb of 500 easily and it was stable.
with the 1:2 divider i was limited to 1825, which is 455fsb.

could this be correct?
a max fsb difference between memory dividers?
and not a small one but a whooping 50mhz?
im puzzled... ill see if i can reproduce this with the 6600.
Well, a difference between dividers ( max clock speed dependency on divider ) is there ( for sure ).
But I don't remember spotting ( well, didn't tried hard almost at all ) any difference in mem clocking with different CPUs.
But I think it's time to try some CPUs with the same board + settings to see if I can reproduce your findings [ the more you test, the more things you need to test ]
