How to find out the real, maximum possible CPU speed (WITHOUT overclocking) ?

I was running an AMD Athlon CPU on an older Elitegroup motherboard.
Some diagnostic tools show me a modell 1400 MHz (10.5 x 133) 1600+ for this CPU.

Then, a week ago, I changed the motherboard to another Elitegroup motherboard (K7S5A).
Note: I moved the old CPU to the new motherboard as well

Much to my surprise the same diagnostic tools show now a CPU modell: 1046MHz (10.5 x 100)

So the CPU modell changes when the underlying motherboard changes ?

It seems to me that the CPU diagnostic software tools show only the effective Mhz
But how do I get the real, maximum possible Mhz of the current CPU (WITHOUT Overclocking) ?

I assume that the new motherboard is setup with FSB of 100 in contrast to 133 on the old motherboard.

How can I change the FSB from 100 to 133: Is this possible by Software, BIOS or Jumper ?

How do I find out all possible combinations between CPU speed and FSB speed ?

It's in the BIOS.
If you install another BIOS (there are some good ones listed in the Elitegroup
or HoneyX forums, you will have more speed options.
I use the HoneyX BIOS and it is excellent.
I find that the 138/138 speed works the best when dealing with a 133MHz core
cpu.
There is a free program called SpeedFan which will allow you to try different
FSB settings while in Windows with even the original BIOS.

Look at this link for good info on the K7S5a motherboard:
