How to find out the real, maximum possible CPU speed (WITH..

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.
