Small overclock help

I am modding my best laptop. I really don't want it bricked but my Pentium 4 dual core @2.2GHz is bottlenecking my eGPU. I only need a .2-.3GHz overclock and I have the means to cool it.
Not only am I scared, but there are other problems. My computer almost boots too fast and I don't know the key (probably F1 or F2).Therefor I have no idea as weather my BIOS is locked, and I don't know if my PLL has SMBUS to move the fsb (I would assume so though because I've only ran into that problem on my Dells, which are impossible to overclock). I have an Asus K50IJ, the motherboard name was very unspecific in Dxdiag, it was something like Asus motherboard, and I don't remember my BIOS. I will have this information in a few hours.
What replaces the CMOS battery on laptops, is it just the battery? I haven't bricked a laptop yet so I've never had to do anything to it, no chances with this laptop though. What are ways to unlock BIOS also, just in case? And one last thing, will taking the battery out and leaving it like that and running off AC then unplugging the computer to move reset BIOS like removing the CMOS battery.

 

What is an eGPU?

How do you know that .2 or .3 GHz overclock is 'enough'?

Notebooks have a CMOS battery just like a desktop. Unplugging the AC with no battery installed will not reset the BIOS.

I would say you are ill prepared to mod your computer - you will certainly brick it.

Save up for a new system (while taking into consideration how much you can sell your current system(s) for) and get a real performance boost.

When you consider that your cpu is surpassed by netbooks these days, 'modding' such an old system is mostly for learning purposes, imo.

Good luck.

 

An egpu is an external graphics processing unit, a desktop graphics card on a laptop.
I know going to 2.5GHz is enough because I'll only be needing 2.4GHz for 3years until I get my desktop. My desktop is so beast I cannot buy it now. Until then I'll stick to fallout 3 but it requires 2.4ghz and bottlenecks my gpu.

 

While your system might pass the 'min' system requirements for FO3, it is nowhere close to the 'recommended' (by a long shot... even after it is overclocked).

Fallout 3 PC System Requirements Released - Video Game News, Videos and File Downloads for PC and Console Games at Shacknews.com


To put this in perspective for you; your system's passmark score is ~278 while the recommended system is ~1300.

Keep playing with your bottlenecked eGPU as long as you can stand it - no amount of 'mods' will fix your current setup.
