Athlon 2500XP Barton - Is this considered to be "overclocking" ?

Hi folks,

Motherboard is Asus A7N8X deluxe PCB Ver 2.0 which supports a 400 FSB
CPU is Athlon Barton 2500XP ("Real" Internal Clock Speed is 1.83Ghz)
This CPU officialy supports a 333 FSB
Memory is Crucial PC3200 (CAS=3)

I understand the "Official" motherboard settings I should be using
are:
CPU exteral frequency = 166 (This equates to a 333FSB since the Barton
is 'dual pumped')
CPU Multiplier = 11 (166*11=1833 the CPUs official internal clock
speed)
Memory Frequency = 166
Memory is in sync with FSB

However here I am really running the memory at PC2700 speed and not
really taking advantage of the faster potential speed (PC3200). Also I
am not using the FSB 400 supported by the motherboard.

So what if I set:
CPU exteral frequency = 200 (This equates to a 400FSB )
CPU Multiplier = 9 (200*9=1800 i.e. slightly less than 1833 the CPUs
official internal clock speed)
Memory Frequency = 200
Again memory is in sync with FSB

So in this scenario i.e increasing just the CPU's external frequency
but not the internal frequency considered to be 'overclocking' ?

Is this scenario:
a. Likely to be less stable (than the previous 'official' scenario of
333 FSB)?
b. "Stress" and thereby reduce the "life" of the CPU ?
c. Invalidate the warranty ?

Also, what are the suggested 'reasonable' overclocking settings
advisable for the Barton 2500 ? (i.e. running the internal CPU clock
at higher than the official 1833)

Any advice or experience appreciated.

Cheers,
Arif

w0rd to that....why run it at 1.83ghz?

up that multipier.....hit 2.2 with 400fsb and mem and be happy

I agree, you can definitely run it at 400Mhz FSB. If you do leave the
muliplier alone, make sure you have ample cooling for your CPU.

does anyone know where to find out how to change your multiplier setting to
get higher than 11x on a Barton 2500+?
Thanks,

I'm still running at 1.83 mhz.

You can't change it the BIOS?

Read your MB manual. If your board supports it, it will either be done
with jumpers/dip switches on the board, or in the bios, or maybe both. If
it doesn't support multiplier changes, then you can either mod the bridges
on the cpu or use some other method of changing it. The ways are many.
Maybe this one.

Flash the latest BIOS to your Motherboard, and then just change the
mulitplier in the BIOS.
