Hello. I'm trying to overclocking my gf4 ti4200 and i need certain questions answered. What is a reasonable oc for a ti4200? what have other people pushed their cards too? it's a little hard to test because of the lack of sensors on the board, so i dont know how far i should go. Also, what firmware has the highest performance with the ti4200 / gf4 series? and what program should i use to overclock, coolbits 2?
