OK< i installed Coolbits now and still the same thing, I do however have clocksettings in right click part now when it dissapeared when activated SLI. So even if I set my clock from 371 to 372 it fails and says that I have to lower my clock settings and try again. Any help would be really nice, sry to keep posting on this subject, but my last 2 post never recieved any replies, at least helpful, just why overclock 2.....my reply...why not?
