Overclocking the ASUS G75VX

Hey, i'm wondering how to overclock further the ASUS G75VX, i don't know which model but i these are the specifications.

ASUS G75VX

Intel Core i7-3630QM CPU @ 2.40GHz (8CPUs)
8GB RAM
nVIDIA GeForce GTX 670MX
Windows 8
DirectX 11

Now.. to get back to my question, i don't know how to further
overclock the laptop other than using my current nVIdia Inspector
overclocking settings:

+135 MHz on GPU
+1000 on Memory

I can't go further, i've heard rumours other people being able to
go further than this.

If anyone is nice enough to help me out, please give me simple
instructions, i am a total newbie to overclocking, this is as far as
my overclocking skills go, i don't know otherwise.

-------------------------

NOTE: Yes i've tried using Total Commander, using the command lines to start nvidiaInspector with, and also tried placing a .bat file consisting with the command lines for overclocking, it wouldn't run, it would ask me for permission to run it, but nothing would start.

>> The command lines i was talking about was:
-setVoltageOffset:0,0,0 -setGpuClock:0,2,790 -setMemoryClock:0,2,2800 -forcepstate:0,0

I think that was the command line, i copied it from a topic from the ROG ASUS website when they we're talking about
overclocking the ASUS G75VX, the "setGpuClock:0,2,790" i believe was the 790 MHz GPU clock, i only came as far as 736 MHz in total with the +135 MHz boost.

To finish this wall of text off, i'd like to know how to further unlock the overclocking limits and safe overclocking values
that gives good performance boost in games and are stable to use.
To repeat, please give me simple instructions as i do not know much about overclocking, all i've heard about are rumours and guides i don't understand.

Thanks!
Hope to see answers soon,
NAD.
