I have a notebook pro with i5 and 8gb ram.
What I have discovered is that if you run GPU-Z it will show 1252 for both core and memory frequency.
But if you enable the option to save the sensor info to a log file and start a demanding game, when I go back to the log file the memory has stayed constant at 1252 but the core goes all the way up to around 1600 (1632 was my max), as soon as you switch apps away from game it drops all the way down
