Overclocking Help?

Hi I was just wondering how would u guys configure your bios? My stock speed, I believe, is 1.8ghz. I was just wondering what you guys set your bios to if you wanted to o/c to 2.5ghz. I know it sounds like a big jump, but my buddy said i'm fully capable of doing it. The thing is my computer keeps on restarting even when o/c'ing to 2.2ghz. My CPU is idling at around 36 degrees my case is around 15, but on load my cpus is around 45 and case is around 17 (this is set at 2.5ghz).


here are the settings ;

CPU freq.=200hz
CPU Multiplier=12.5
MEM freq.=200hz
Memory Time
SDram active precharge delay = 8
SDram RAS-CAS delay = 3
SDram Ras precharge delay = 3
SDram CAS latency = 2.5t
FSB spread spectrum = disabled
AGP Spread Spectrum = Disabled
CPU VCORE = 1.800V
Graphics Aperture Size = 512MB
AGP Freq = ?
System BIOS Cacheable = Disabled
Video RAm Cacheable = Disabled
DDR Reference Voltage = 2.7V
AGP VDDQ voltage = 1.7V
AGP 8x Support Enabled
AGP Fast write capability - Enabled


SPECS:
AMD mobile 2500+
ASUS A7N8X-X Mobo
1GB Samsung pc3200 DDR400 RAM
Volcano 12 Heatsink/Fan
BenQ DW822A 8x DVD-RW
160GB Seagate 7200rpm 8mb Cache HD
420W Thermaltake PS
XFX Nvidia 6600GT o/c at 500hz/1.1ghz

Well, if it keeps rebooting, some component is holding you back and you need to figure out what it is by using small steps.

You should test your ram, cpu and fsb separately to see how far each one can go. I say fsb since some motherboards just won't work at all if the cpu fsb is set too high.

Test the CPU first by setting your ram and fsb(cpu freq) at low settings - 166mhz or less.
Then try higher multipliers such as 15x166mhz to get as high as 2.5ghz.
If that works, and it can boot and run properly, then your chip is good to go.

Next, I'd leave the ram at 166mhz or less and raise the cpu fsb as far as 200mhz or try even higher to see how far it will go. Don't forget to decrease the multiplier while you're raising the fsb.

Then start raising the ram speed (MEM freq) until it starts having problems. You can raise the DDR voltage (memory voltage) if your ram is giving poor results, but most people stay around 2.7-2.8v.

For reference, here's how my amd 2400+(non-mobile) is currently set up:
nforce2 motherboard
CPU/FSB freq: 200mhz
CPU Multi = 11
MEM Freq = 200mhz

CPU voltage = 1.65v
DDR voltage = 2.77v
MEM timings = 2-3-3-6 (3x 256mb corsair xms pc3200c2)

After you get your system stable, also look into decreasing your cpu voltage
