Overclocking my new Core 2 Duo System

I just built the following:

Core 2 Duo E6300 1.8Ghz
Asus P5B Motherboard
2 x 1 GB DDR2 800 (PC2 6400), with 5-5-5-12 timings and 5 CAS Latency.

I have never done over clocking. I'm wondering how I should set the following bios settings? I realize I should start low and slowly increase as long as I maintain stable temps, but I'm not sure specifically WHAT settings to increase. Here's what I see in the BIOS:

1. CPU External Frequency. This ranges from 100 to 400. Where should I set it?
2. Memory Voltage. Has 1.8, 1.9, 2.0, and 2.1.
3. CPU VCore Voltage. Currently set to auto.
4. FSB Termination Voltage. 1.2, 1.3

I believe these are all the settings related to Overclocking. Currently everything is set to the default.

I think a good start is to try 2.4 Ghz and see what my temps are. Then perhaps 2.8 Ghz, then 3.0 Ghz.

My question specifically, is what to set the above settings in order to achieve the higher speeds. Thanks!
 
Update: I think I'd be happy just going to 2.8 Ghz since I'm using the stock HSF. After doing a little research, it seems I can set the FSB rating to 400 Mhz and the memory to PC2-800 and I will get 2.8 Ghz. My question is do I need to change the CPU voltage or other memory settings to achieve this? Thanks!
 
try it at stock vcore, see if its stable. With the stock HSF, you need all the help you can get.
 
1) set to 401fsb

2) Memory needs to be 2.1v at least...Most PC2-6400 is stock 2.1v...

3) Set the vcore right now for 1.4-1.425v

4) 1.3v

I have this memory: http://www.newegg.com/Product/Product.asp?Item=N82E16820145590

The vcore is 1.9V. I should set to 2.1V?

The E6300 lists vcore as 0.850V-1.3525V. I assume this is just "recommended" but I can set to 1.4 manually? What is the "auto" vcore on it anyway?
 
I would try 2.0v first then.....by the way that is vdimm not vcore...

set vcore to manual then 1.4-1.425v...the mobo undervolts a bit and droops even more under load...
