My motivation is, I want to experiment with overclocking the bus speed in 7500-9600 computers. When I was younger, I always wanted a Power Computing unit with 60MHz bus. When I got a beige G3, I ran the bus at 83.33MHz, and it worked perfectly. When I got a Gigabit Ethernet G4, I ran the bus at 120MHz, and it also worked perfectly.
I just read an article on how Power Computing got their bus to run at 60MHz, and in that article, they said that some 7500-9600 actually will run at 60MHz. Now as history has shown us, that isn't true for the majority of 7500-9600 out there. But, I intend to try. I just bought 7300, 7600, 8600, and 9500 mainboards, so I can cherry pick and maybe see what differences there are between these models. I theorize that the 7300 may do well due to lacking the AV circuitry, one less thing to worry about, but that theory could be way off, as could my hopes to get anywhere near 60MHz. I will consider 53.33MHz to be a massive success. This subject should probably have its own thread.
Long story short, I want the highest spec RAM I can get. I am not looking for higher memory performance necessarily, I am looking for extra stability. EDO is considered to be higher spec than FPM, and I have heard it works with zero issues in these Macs, so I think it would be more desirable for me, but please let me know if that is incorrect.
