Here I am determining the cutoff or change in the PCI divisor for each FSB setting.
Please correct or add to this data as you have tested.
Here is what I have found but it is not complete.
Setup: A7V133/Duron700
Multiplier stays constant @7.0
Vcore via jumpers @ 1.70
JumperFree mode to set FSB
FSB and memory speed are set the same in BIOS.
Note: I just know this won't format correctly!!
FSB Divisor PCI Mhz
117 1/3 39
120 1/3 40
121 1/4 30 *******
122 1/4 30
123 1/4 31
125 1/4 31
126 1/4 32
128 1/4 32
130 1/4 33
132 1/4 33
133 1/4 34
135 1/4 34
140 1/4 35-unstable

see next post........

What a surprise..I thought the numbers would be all scrambled.
Anyway, at about 120 the divisor changes and somewhere above 140 it should change, but I can't get there yet. Maybe someone else could finish this.
IF..the PCI devices in a particular system work better at the lower PCI Mhz settings, then a setting between 122 and 133 is better than going just below 122, say 118 or 119.
So, I decided that a setting of 133 is as high as I want to go and still remain stable.
Maybe this has something to do with the fact that the DIP switch settings jump from 110 to 133. At 110 you would get 37, which is still a good speed.
Well, that's my rambling and 2 hrs killed time.
Chime in anyone!!!
