with slightly more heat but runs without crashes -actually it runs ok up to 20% without problems...
I am using this settings when I am playing Lineage2,Aion,Battlefield2 etc etc and have no problems at all.
You can set this in Nvidia system tools as an automatic switch when you run any app or game....
Hope this will help ... Yarys

forgot to say before i play i am using game booster
http://www.iobit.com/gamebooster.html
so what i do is this:
I had set the nvidia system tools to overclock when i run game booster so it will overclock system at saved settings (-15 or 20percent overclock -)when launch this app,and then:
1.run game booster
2.click on configure
3.show all current processes
4.check all and click Remember to keep this settings
5.unclick the box nTunecmd.exe - to keep overclocked system on
6.OK
7.and finnally Button Switch to gaming mode ..
Sounds complicated but this is just for the first time to be done and then its all set and next time its just 2 clicks and is all done...
It helps to me without destroing my cheaper laptop thanks to nvidia software for safe overclocking and i am able play (at work

)when i cannot use my desktop ...
