What do the numbers following the memory ports on a motherboard mean?
I'm looking at motherboards and I see after all of the memory port specs a set of numbers. For example, this one says "4×240pin DDR3 1866/1600/1333/1066". I know what the 4/240pin and DDR mean, but what does 1866/1600/1333/1066 represent? It doesn't seem to be important, but I'm curious.

That's simple: "4x" is the number of "240pin" slots. "DDR3" is Double Data Rate rev. 3, and "1866/1600/1333/1066" are the supported Frequencies in MHz of the RAM.
It means it has "4 240 pin DDR3 slots supporting the different frequencies of 1866 MHz, 1600 MHz, 1333 MHz, and 1066 MHz."
