I doubt my RAM is running at the correct speed.

Solution
Programs like CPU-Z actually report the clock frequency going to the memory. But since the memory is DDR (Double Data Rate), the memory operates at twice the clock frequency.

In this case here, the memory is operating at 1066 MHz x 2 = 2133 MHz (MT/s). So it is running at its rated frequency of 2133 MHz (MT/s).

The SPD tab selected in CPU-Z shows the programmed frequencies etc within the memory module SPD chip, although it does show memory frequency and bandwidth. Usually to see current memory frequency select the "Memory" tab. And remember the module operates at twice the shown frequency (DRAM Frequency).
