You shouldn't need to increase the Vcore on that unless you are doing an insane overclock, which I doubt you will be able to achieve stably. Since that CPU is 2 GHz, it will be easy to OC since the multiplier is 10. Just increase the FSB by increments of 5. So...
200 MHz x 10 = 2.0 GHz (your current speed)
205 MHz x 10 = 2.05 Ghz
210 MHz x 10 = 2.1 GHz
215 MHz x 10 = 2.15 GHz
220 MHz x 10 = 2.2 GHz
225 MHz x 10 = 2.25 GHz
230 MHz x 10 = 2.3 GHz
230 MHz x 10 = 2.35 GHz
240 MHz x 10 = 2.4 Ghz
You will easily be able to get to 2.2 GHz, and maybe 2.4 GHz. Just remember:
Always monitor your temps (use SpeedFan) while stressing the CPU and for the first couple of days with the new OC. Don't led your load temps go above 60 degrees.
For every 50 MHz you increase the CPU, you should do a quick (10 - 20 mins) stability check with Prime95 to make sure everything is OK. If you get any errors, stop, and reduce the frequency.
Once you are at your target frequency (I would stop at 2.4 GHz), run Prime95 for 1 - 2 hrs. to check for stability. Always monitor temps.
Once that checks out, run Memtest86 overnight to check that your RAM is stable. You may find that you need to increase the timings a little if the Memtest86 gives errors.
If your computer refuses to POST, reset the CMOS and try to boot again, remembering where you were. You should probably drop the speed down 100 MHz if this happens.
