you didn't get gipped. You have dual channel ram...so only when it runs both channels its 1333 roughly. Multiply the frequency that it's showing by two, and you will see what I mean.
Then put your laptop under a heavy load like an intensive game, and run the monitoring program again. Then you should see what you want to see. better yet, run memtest..it puts a helliva strain on ram.
what has basically happened is that your ram is under a light load, so it adjusts the voltage and runs off a single channel. This saves power, and also generates less heat. Its very common. Fwiw, im pretty sure they dont even make ddr3 ram at that slow of a frequency. The ram that you are running has a nice, low latency/timing, so it's actually fairly good for a 1333mhz chip btw
