Why is my Athlon XP2500 showing up as XP 1.1 Ghz on System Info?

I have recently installed a new MB and CPU (Athlon XP2500 and Asus
A7N8X-X
The computer is running fine except that when I look up System Info or
on boot up, my CPU is displayed as XP 1.1 Ghz.
Have I done something wrong on install that my CPU is running slower?

Thanks....Ed

You're running at 100FSB X 11 multiplier. I'm running that chip at
200FSB X 11 multiplier getting a 3200+!
Press DEL on startup to enter the BIOS. You want FSB 166 bare
minimum. Lock your RAM at 100% so the system stays rock solid like
mine.

Probably you are running your FSB at 100MHz. Go into the BIOS (and/or
check your jumpers?) and bump it up to 166.

166.666/100.000 ~= 1833.333/1100.000. Your XP2500+ runs at 1833MHz.
 
I don't know the situation with the A7N8X-X, but some mobos make you throw a
jumper to change FSB speeds.

That's true. I saw that with a Soltek board recently.

Thought Soltek's BIOS would let you OC without jumpers. If you have to do
hardware, back to the drawing board for me. :( Oh well, 3 months til the
snow flies.

166 or 133?
I just looked at my BIOS and the correct processor frequency is set (I have
an Athlon XP2000+ and it shows at 1.67GHz).
But it shows an FSB of 133. Do I have to set a jumper manually on the MB to
266MHZ?

I have the Asus MB too.
Thanks for help.
 
No - 133 is correct. You need to multiply the FSB by 2 to get the actual
value. In other words:

100Mhz x 2 = 200 Mhz FSB
133Mhz x 2 = 266 Mhz FSB
166Mhz x 2 = 333 Mhz FSB
200Mhz x 2 = 400 Mhz FSB

So, you are running your XP 2000+ chip correctly.

An Athlon XP2000 runs at 1.67Ghz
