Is this true of all Macs and all RAM and all upgrades? I had some guy in a

The RAM is connected to the DRAM controller chip which, in turn, is connected 
to the (common) 50 MHz bus. The CPU rides on the 50 MHz bus, to.

Most CPU upgrades run the bus at 50 MHz or a little slower.

Also, most currently manufactured RAM is 50 ns or 60 ns, not the 70 ns which 
was manufactured when the 9600 first came out.

If there were to be ANY problems, it would be with Macs which had the older 
70 ns RAM, combined with CPU cards which intentionally overclock the common 
bus.
