Overclocking my notebook..safely

I would like to overclock the GPU in my notebook (G1s), but not so much that it will overheat. It sits on a raised aluminum cooling pad 24/7 with an external monitor most of the time, so temperature shouldn't be a huge issue. I just want to see noticeable performance increases in 3dmark scores, safely of course. What should I overclock to? What program should I use with Windows Vista Premium 32bit and my nvidia 8600m gt card? Any help is greatly appreciated, thanks.

 

Just try it yourself and see, go slowly bit by bit, get to a temperature you're still comfortable with and is stable. Different notebooks of the same model sometimes have different tolerances, I recall threads where people say their notebooks overheat on stock speeds while others owning the exact same model have no issues. What I'm getting at is even if someone says an overclock of ___ mhz is safe, you should still be careful.

 

Is there software that measures the temp. of the system or is that something I have to do externally. I would assume it's the latter..

 

Usually (at least under XP) the driver measures the temperature of the GPU. It can be found under the advanced settings of the GPU.

I presume you are not very experienced with these things. If so, I would suggest try first playing your games at the stock settings, and only if the performance is unsatisfactory, move on with trying to overclock.

 

I tried Rivatuner and it worked perfectly: Z84JP, Vista Home premium UK, GF 7700 GO 512 Mb. You can find it at http://www.guru3d.com/index.php?page=rivatuner

If you have not much experience with overclocking I would be careful if I were you. So if you try it then do it gradualy and only in small steps at a time.

Besides: overclocking to improve 3D mark scores is one thing, but often the performance increase due to GPU overclocking is a bit disapointing when playing the real games

Normaly I don't use my notebook (or desktop) with an overclocked CPU and/or GPU.
