Uh, some bad news for your numbers, Chris.
Digital Audios already have a 133MHz bus with 4x agp.

Well, I am about to pick up a 533MHz G4 from a DA and put it into my
Sawtooth. Once I get it, my motherboard is getting removed and having
some dip switches installed. And these dip switches will be
controlling
my bus speed. Settings above stock that will be tried are 105MHz,
120MHz, and 133MHz. I will test stability and RAM slot functionality
at
these speeds. Anyway, I have the following 2 questions:
Can a dip switch replace a register? Or resistor? Basically, should I
probably include this in the setup? I imagine the answer is yes if the
resistors are anything other than 0ohm.
Is AGP timing related to bus speed in this machine? The 120MHz setting
reduces PCI speed to 30MHz, while the 105MHz setting increases it to
35MHz. PCI speeds are not important to me but I dont want to slow down
my AGP bus.
Speeds I will eventually test are (bus/processor):
105 / 577.5
105 / 630
120 / 540
120 / 600
133 / 600
Note that this will be after testing all of the bus speeds at the 4X
setting to thoroughly test the bus speed overclocking first. I dont
expect to get past 600MHz but I do know someone who has gotten 650MHz
out of one of these processors, though his computer was run in a cool
basement. i will also be trying to fashion a better cooling system.
Thanks for any help
