3400+ Clawhammer overclocking?

Hi, I have the following spec and I was wondering how far I could safely
overclock this kit:

AMD 64 3400+ Clawhammer core
MSI K8T Neo FIS2R (754)
PC3200 DDR RAM
Powercolor 9800 Pro 128MB Graphics
Artic Cooling Silencer 64 heatsink/fan

My CPU temperature is 40-45C idle and 45-56C when stressed and is currently
at stock speeds with Cool'n'Quiet on and Dynamic Overclocking off.

Any ideas how far I can safely overclock this? Also, any advice about *how*
I can overclock this? Is all OCing done through the BIOS? Or is it through
motherboard management software? How do I know how safe it is when I'm
OCing?

TIA.

Forgot to add - I have a CG revision chip. :)

My old clawhammer core 3000+ gets pretty close to max at 2330MHz (10x233).
As 233MHz is max FSB speed I can set in the bios, I can't go any higher,
but since to reach this speed I have to have a minimum of 1.675v I don't
think the cpu will go much higher anyway. One thing you will need to do to
make sure it's the cpu that limits you is to manually lower both the ram
bus and the HT link as they both overclock with the rise of the system
bus. And I'm sure you will need to raise vcore substantially to get any
appreciable overclock. I guess safe is when the temps don't get too high
and the system is stable under full load.

sorry for butting in and drifting a bit but - my 3200+ (A64) 2.2ghz
newcastle is running at 2.5ghz soft as smelly-stuff, simply by upping the
fsb using core centre. is this an average o/c for a 3200 n/castle or could
it go lots higher if i play with bios settings ?

Sounds good, I have same CPU (week 16 2004) with stock hs/fan on it and
it takes 1.60v to pass Prime95(FPU test) @ 220x11.

Good luck,
Ed

228fsb stock hsf default voltages etc... been running fine since i did it a
few weeks ago :-)

If you're still at stock vcore with your 3200+ you should be able to get
more out of it. Sounds like you got a real good one.

Hi,
Have you tried running AMD's Corecenter? You can ask it to slowly
raise the FSB speed while you monitor the CPU temperature, all from
Windows.
I have AMD 64 2800+ on the same Motherboard as you, and I raised the
FSB speed from 200 to 220, "upgrading" my processor from 1.8 GhZ to
2.0 GhZ.
Runs fine, temperature is between 52 and 60 Celsius.
