Nvidia nvs 140 m overclock

I just tried to overclock my video card and got some stunning results, more than 50% of overclock freqs.

be careful with that! if your notebook gpu dies of overheating you’ll be sorry… :o

Temp stays around 83 to 85 degrees so it should be ok. What I am missing now is a decent driver, the stock Lenovo driver is 178.74 while nvidia is already at 260.xx. Can t really find anything for XP, may be I should give another try to W7… any idea out there, where are the latest driver for my card?
