Hi folks

Can anyone point me to a good web site with a clear explanation of what RAM
works in what macs - specifically, does it matter using 100 type which can
run at different speeds - this is for a G4 400.

a tech explanation follows - but i want to know if mixing the different
types matters...

thanks for any help
