Overclocking Inter Pentium Dual Core e5800!!!

Hi Guys...
I'm Totally New in this overclocking thing and I need serious help!!
I have the Intel Dual Core e5800 currently at stock 3.2 ghz but I want to increase its speed. I do not know how to do it and need help..
Plz guys help me as I am totally new in Overclocking..
I know that this post is not complete and I have to add more information.. but I do not know what to add plz tell me what to ad more for info and plz guys helps me..

Thanx in Advance..

Post your complete system spec's in detail, including the make and model of motherboard, the EXACT model of RAM including the quantity, etc.

Okay.... My Mainboard is ASUS P5G41T-M LX with bios version 0604 and I have 4096 Mbytes of RAM 2x2 Kingston
and I have XFX ATI Radeon 4670 graphics card...
thats all..
If somethings left plz let me know...
And plz provide me steps as per my own bios bcz I am not such good at bios setups..

Okay... I got some more info using CPU-Z..
Acoording to CPU-Z, My core specs are...
core speed = 1211.3 mhz
multiplier = x6.0
Bus Speed = 201.9 mhz
Rated FSB = 807.6

My Memory Specs Acoording to CPU-Z..
DRAM Frequency = 403.8 mhz
FSB : DRAM = 1:2
etc..

According to Core Temp,
Processor Info:
Model = Dual Core E5800 (Wolfdale - 2M)
Platform = LGA 775 Socket T
Frequency = around 1512.36 mhz to 1915.66 mhz
VID = 1.3000 v
Lithography = 45 nm

my temps are..
core #0 = 42% with load 0-3%
core #1 = 42% with load 0-1%

I hope this Info helps to give you all an Idea of my system...

Okay... Here is a pen picture of my bios screen===
My bios consists of 6 tabs which are Main, Advanced, Power, Boot, Tools and Wait respectively.
In the Advanced Tab there are 6 go-to options namely..
1) Jumperfree Config
2) CPU Config
3) Chipset
4) Onboard DevicesConfig
5) USB Config
6) PCIPnP
I assume that this screen ands its options will be most important for OC. Okay Moving on and going into Jumperfree Config(which I assume will be Important) We find the following options :-

PCI/PCIe CLK Status [Enable]
AI Overclocking [Auto]
DRAM Frequency [Auto]
Memory Voltage [Auto]
NB Voltage [Auto]
VTT Voltage [Auto]
CPU Vcore [Auto]
Auto PSI [Enabled]

And in the CPU Config there is info about my CPU which tells that it has BUS Speed of 800 mhz and various settings like CMOS Ratio, CIE Support, CPUTM Function, etc..

Okay.. These are the only things which I assume will be important in the Anvanced tab..
Now Moving on to the Power Tab, We Find..
Suspend Mode [Auto]
ACPI 2.0 Support [Enabled]
ACPI APIC Support [Enabled]
Anti Surge Support [Enabled]
APM Config(which is a go-to option)
Hardware Monitor(which is a go-to option)

Going inside the Harware Monitor We find...
CPu Temp [54 C]
MB Temp [35 C]
CPU Fan Speed [1318 RPM]
CPU Q-Fan Control [Enabled]
CPU Fan Profile [Optimal Mode]
Chassis Fan Speed [2556 RPM]

Vcore Volt [1.248V]
3.3V volt [3.280V]
5V Volt [5.222V]
12V Volt [11.985V]

All Right, this is my bios screen and its options(which I think is important)..
There may be things which I have missed. If there are plz let me know. I am here to provide u all the necessary info of my pc....
So plz guys guide me towards my first overclock...

Here are the pics of my bios screens :-
