Hey everybody, I have been succesfully overclocking this card for a few weeks, until recently it acted up. I can't remember exactly what I did--I'm pretty sure it just changed out of the blue, as far as I know--but I use coolbits 2 and my Nvidia overclocking adjustment panel thing suddenly shows it as 400/2.50GHZ. The cards default is 375/1.2Ghz, and it had appeared as that earlier when I purchased it. If I lower or raise either slider and test changes, it will say my computer can't run it. If I "detect optimal frequency", it will set it at about 480/2.68, but it won't really happen. (If I open up the panel again it will be reset at 400/2.50) I have reinstalled my drivers and tried different versions, nothing has worked. Any advice? Thanks!
