there was a test application to see if your sawtooth could accept a dual cpu upgrade or not
i believe i ran this test on my sawtooth yeras ago and it said that mine is compatible?
i remember it made direct reference to northbridge
https://discussions.apple.com/thread/118381i think that reader50 is partially correct; in that SOME Sawtooth machines are incompatible, but if your particular machine has the vWhatever uninorth then u are in the clear..
like i said i think i ran this test on my 450mhz machine and it was ok
but my friends machine is a 400mhz model; it may not be the same capability, but it just might! tbh i have done that test on a few sawtooths and usually gotten the green light for dual processors everytime.. which leads me to think they made more of the compatible uninorth then the incompatible or maybe i been lucky
anyways tbh im not too concerned about dual processors...
i honestly forget which cpus can be swapped into a sawtooth
7400 (100mhz) | 7410 (133mhz) | 7450 (133 mhz) | 7455 (133mhz)
i know its a 100mhz machine, so any Mhz #'s from machines that have a 133mhz bus
will not show up as the same # on the sawtooths' 100mhz bus...
that much i remember at least
so taking a cpu from an early Digital Audio G4 (7410)
or a later DA/Quicksilver (7450)
or a 2002 QS (7455)
will not give the same Mhz
933mhz / 133 = 7
so 7 * 100 =
700mhzthis is how it works right??
divide mhz by FSB to get multiplier
than times the multiplier by the new FSB
to get the achievable MHz of the processor
so a 933 mhz qs cpu in a sawtooth will
only show up as a 700mhz
800 / 133 = 6
6 * 100 =
600 Mhzand likewise a dual 800 QS cpu
will yield dual 600mhz in a sawtooth,
wasnt there also a hack to force the sawtooth to a 133FSB via OC?
733 / 133 = 5.5
5.5 * 100 =
550mhzso a digital audio 733 mhz cpu would only yield
550mhz in a sawtooth
1000 / 133 = 7.5
7.5 * 100 =
750Mhzso a QS2002 dual -1ghz
will show up as a dual 750mhz in a sawtooth
do quicksilver CPUS work stable in a sawtooth?
