Ram frequency problem

[TeoPap]

Hello . Today i opened up speccy to see how my pc is going and i saw that my  8gb 2133mhz ram works with 1000mhz frequency . Is this normal ? where is the other 1333mhz ? I will provide a photo :

It's working correctly. 

1066MHz x 2 = 2133MHz

DDR = DOUBLE Data Rate, that's why x2
