Can 1800+ be overclocked?

I have an Athlon 1800+. I haven't had any success overclocking it. Even if
I turn the bus speed by even just a few Mhz, it'll crash as soon as I run
something intensive (ex: a 3-d game). I tried turning up the voltage, too,
and still no luck. And the temperature is always pretty low.

Are the 1800+ inherently non-overclockable, or is that I just got unlucky
with the CPU?

Additional hardware info:

ASUS A7V333
Radeon 9700 Pro
SB Audigy

You should be able to overclock any 1800+. How much depends on the model
and how you do it. Multiplier x FSB = CPU speed. Changing the multiplier
only affects cpu speed. Changing the FSB affects the whole system and is
probably the cause of your problem. For specific answers I'd need to know
which model you have, or the cpuid. See link below for more info.

It's clear you have a Palomino core. And since you have something that
won't run right when you raise the FSB, there's only 2 alternatives. You
can unlock the Palomino multipliers by closing the L1 bridges and then
select up to a 12.5 multiplier with your bios. And forget the up to 14 the
manual says. It won't work past 12.5 unless your board has control of the
5th multiplier bit, and I'd guess it doesn't. That would get you to
1666MHz (2000+). Or, as I would probably do, just change the cpu into a
2100+ by changing the default multiplier to 13 using the L3, l4, and L10
bridges. That would get you 1733MHz (2100+), and if you ever figure out
what's keeping you from raising the FSb speed, you might get another
100MHz out of it by doing so. Here's something to show you the bridge
settings for multipliers.

Do you think it's the Motherboard or the CPU that's preventing me from
having a stable overclocked system via the FSB increase?
I'm using ASUS A7V333 as a motherboard. Perhaps I should post another
thread asking if anyone had a successfully FSB overclock with that board

My second question is: If I go with the "closing bridges" and "changing
muliplier" method that you suggested, what would happen if the CPU coudn't
work stably at 2000+ or 2001+ speeds and I was forced to go back to 1800+?
Is there a reversal for the "closing bridges" process (ex cutting the
bridges), or is "closing bridges" permanent? I don't want to ruin the CPU,
although it would give me an excuse to go get a newer one

I doubt if it's the MB, it's capable of FSB speeds over 166MHz. And I
would really be surpised if it was the cpu. My guess is one of your pci
cards or video card. Seems I've heard of bus problems with the sound card
you have, but I don't recall or sure. It6 could very easily be your memory
too if you've only got PC2100 ram. adjusting the speed of the ram could
help.

KT333 chipset is capable of way over 166Mhz FSB.

Cutting the bridges is pretty easy. Closing them is harder. When I did
mine, there weren't any Tbred B cores or Bartons out yet. If there had
been, I'd wouldn't have even messed with the Palomino core. If I were you,
I'd just buy a new cpu and sell the 1800+ on ebay. If you've got an old
cooler to sell with it you can get a decent price for it. Let me check
real quick. There's 2 used working 1800+'s selling or over $40 with
bidding ending in less than 8 hours. They normally go up during the last
few minutes of bidding. It would be a nobrainer for me.:-)

I have also a XP1800, a 9700pro and a audigy2zs... running it at 2138 mhz
(12,5x171) - alas at 1,95 v-core - and at 387/355 (GPU) on an via kt333
(epox 8k3a+) with pc2700; getting 5620 3dmarks03 and 38.000 aqumark....
well, so it's worth the fun...
