Is it worth OC'ing m y 420M to 435M speeds ?

I read somewhere that the 435M chips are just 420M but OC'ed. What program do I need ? Is there any Nividia ones ? any cons by the way ? Also I don't have to play around with the volts right cause I won't touch it in that case then. thanks

 

You need Nvidia System Tools it adds the options to the Nvidia control panel.
You can't touch the voltage as they are locked in BIOS so there is no real danger, it won't even invalidate your warranty (unless you mention it to Dell)
Just increase the clock speeds and see what runs stable, PassMark 06 is the usual test. You only need the free version
It runs a variety of GPU intensive tasks and gives you a score at the end. Do a full test at stock speeds and record your score. Overclock your card to the speeds you want, I would aim just above 435m speeds initially and run the test again. If the test fails, crashes or there are artifacts (i,e rendering problems) then lower the overclock and try again.
It's worth doing if you have the time as you will see an improvement and you can even measure the difference!
The other con is that it will make the GPU run slightly hotter, if your at 435m speeds it will generate 435m heat but the cooling is the same in both systems and System Tools comes with a system monitor that lets you know the GPU temperature. Anything above Celsius and lower it otherwise your fine.

 

so what is the max safe temp ?

 

I say 85 Max at 100% usage or While Playing Crysis

 

If you are interested in OC'n the vid, I would also check out MSI Afterburner, I used it when I had the 445M and it worked like a charm for me.

 

just remember, it really depends on the game you're playing. a lot of people like to OC to get high 3dMark scores or just to see how far they can push their systems. it really depend on your GPU usage.

for me, i play games like HoN and project reality and sims. these games are relatively CPU dependent and my gpu usage (using GPU-Z) is usually around 60-70%. when there is heavy fighting going on, the gpu usage drops to like 40-50% which my CPU is usually near 100. in my case, OCing does nothing in terms of performance.
