CPU Clock setting (BIOS)??

i went for on of the deals at Fry's yesterday for an ECS mobo (K7VTA3 V6.0 / FSB 333/266/200 MHz ) & AMD XP 2200+ combo for around $60. i'm trying to put this system together for a relative.

anyway i got everything running installed and running fine. only question is upon boot-up the bios reads the cpu speed at something around 1.35ghz. shouldn't it display a 1.8ghz speed?

is there a jumper or setting in the bios that i need to change. i was going through the mobo manual and it mentioned it should automatically detect the cpu's speed and settings. i did notice the CPU clock was at 100 in the bios, should this be changed?

unfortunately i really don't understand all these cpu settings, FSB, voltage settings, jumpers, etc. is there a guide out there on the internet for me to read up on or can someone here please explain it in a simple way :)

There should be a jumper on the mobo or in the BIOS soft menu for selecting a 100 or 133 Mhz CPU bus clock. You want 133.

i see. the cpu clock settings in the bios can be changed but i didn't "set it" yet as i wasn't sure :)

but it only allowed me to go as high as 132.... is that right?

I don't think that's right. I had a mother board that in order to get 133 and above you had to change a jumper. Does your manual say anything about a jumper setting?

no that is not right.
You need to find the jumper on the mobo that changes from 100 to 133 FSB.
Should be very early in the manual.

Jumpers JP2 and JP3 are the ones you need to change.
Just above the speaker connection.
From default you should change JP2...JP3 will remain the same as 100FSB

100 FSB
JP2 - Short 1-2
JP3 - Short 1-2

133FSB
JP2 - Short 2-3
JP3 - Short 1-2

166FSB
JP2 - Short 2-3
JP3 - Short 2-3

thanks for the add'l input guys. i also checked the online manual and am gonna try changing the jumper settings on the board later when i get home.

so what exactly is this "CPU CLOCK" setting in the bios for?
