I have my Gigabyte Geforce 6600 GT (pci-express) @ factory default speed, what can I safely overclock it to without having to buy extra cooling devices?
what do yo mean? th coolbits tingy? if you ment that, yes, you can do it with all nvidia cards. (the thing i wrote only unlocks the feat. in the nvidia forceware diver
but,.. to see at what speeds you can put it.. well.. lets say, the card usually runns unstable before you get heat issues
you need to find some good software that monitors your overclocking and will tell you whats safe and whats not!! GO TO THE OC SECTION AND THEY WILL TELL YOU EVERYTHING
