Cpu not running at correct speed?

OK, so theres now just one last problem. Cant seem to get my CPU to run at a
good speed?
I have an AMD Athlon XP 2800+ installed in my GA-7N400 Pro2. With default
BIOS settings it reads as a 1500+ cpu on boot-up, so I changed the BIOS cpu
frequency to 166Mhz. Now on boot-up it reads correctly as a 2800+ cpu but in
fact is only running at 2250Mhz....

I have checked and the CLK_SW is set to "auto" ( to run the FSB at 333MHz).
So then I tried playing around with the CLK_RATIO switches to try and
clock-up my processor? (think thats right). Anything under 18x and the
processor ran slower, at 18x the processor ran at the same normal speed -
2250Mhz.
And is it normal for BIOS to report my cpu running at 68 degrees? Just seems
quite hot to me?

Or is it just me and this processor wont run any faster??

I am still a bit new to all this business so if anyone has any tips for me
then it will be greatly appreciated.
Does anyone have the same CPU in the same mobo as me and running at a higher
speed?

Thanks

That's much too hot for any Athlon XP. Check that you have a suitable
heatsink/fan, and that it is attatched properly.
http://compreviews.about.com/od/tutorials/ss/DIYCPU.htm . Incorrect
application of the heatsink compound can often be the biggest factor in
problems such as this. You may also wish to increase the airflow in and out
of your case. See if the temperature drops with the case open.

The Athlon XP doesn't run at its' PR Rating (2800+). That rating is only a
comparison of the performance to other (Intel) processors on the market.
Processor speed is calculated as multiplier times FSB. You seem to have the
Thoroughbred-B 2800+, so the multiplier should be locked at 13.5x. No
matter how you change the multiplier in the BIOS, it will still default back
to 13.5x. If you multiply this by the FSB (166.66r), you will get 2250MHz.
Any faster than that and you will be overclocking the processor.

ok thanks for your help, at least i know now that im running at the correct
speed, just need to cool my case down now.
cheers

is there no way i can run faster then?

Neil, you need to know what you are doing to overclock, 2250 is the correct
real frequency for the 2800+ as was explained above. It's a pretty fast
CPU at that! But if you really want to look at exceeding this, try the
group alt.comp.hardware.overclocking.amd

Some motherboards can only be set to the default FSB for the relevant
processors they support (133 / 166 / 200 etc), while others can be set
incrementally (166 / 167 / 168... etc). If your motherboard can't be set
incrementally, there may be a BIOS update that allows it that option.

Download Motherboard Monitor 5:
http://www.majorgeeks.com/download.php?det=311 . Set it up to read the case
and CPU temperatures while your system is running. If your processor is
running 69 degrees in the BIOS, then I would hate to see what it runs at
under full load. If you get towards 85 degrees, you may well end its life.
Your main priority is getting it below 50 degrees under full load, not
finding out how to overclock an already toasting processor.
