hi i have a gtx 660 SC from evga and i overclocked it and it used to run at a core clock of 1202 at all time no mater what map or player on battlefield 3 and now the core clock is going to 1150,1189 what should i do?
 
that is normal. 6xx NVidia gpus from 650ti boost and above have a "boost"clock. which increases the clock speed on demand, and will throttle back depending on temperature, power etc. You can keep the boost clock higher by keeping temps below 70c and increasing the power limit with msi afterburner.
