i have come across a stick of pc3200 ram that is 1GB and i have a friend who is in need of ram pretty badly and is broke. i realize that his ram is only 100mhz but would this work at all in his 450mhz G4?
No. PC3200 is DDR RAM, it has a different connection. SDRAM has 2 notches in the bottom ( that's what the Sawtooth takes). DDR RAM has one notch in the bottom, so it won't even fit in the Sawtooth.
