i have a amd athlon xp 1.8 ghz cpu and installed in to the mother board a k7s41gx but when i look at my system it says 1.15 mhz is this right ???

Sounds about right i think the 1800 XP runs at 1.5Mhz.

Opps let me just clarify, if your cpu is running at 1150 Mhz then it is set wrong in the FSB it should be set at 133 in the bios,if it is running at 1500Mhz then it is running at the right speed.

P.S

On the post screen if it is set up right and the Mobo supports it then it should say XP 1800 on post,if not it will just say 1150Mhz cpu,this can be because your mobo doesnt support the CPU or it is set wrong in the Bios.

some amd cpu's use amd 'power now' mine does, the speed on idle can go down to 1 mhz, but as soon as it has something to do it goes back to 2.2 mhz.
but i dont knoq if your's has this feature, maybe someone more learned than myself could advise.
