DDR 3 memory – clock speed

Recently started looking recent technology and hardware changes , learned few interesting things

Was thinking DDR 3 means triple channel memory but as name stands DDR(Dual data rate)  all DDR , DDR2 and DDR3 are just dual channel memories only

And also regarding advertised clock speed of these like DDR3 1333mhz , 1600mhz and 1866mhz , are not the real clock speeds.

DDR3 1866mhz RAM runs at 930 to 933 mhz on each channel and combined 1866mhz.
