Is my mobo using my ram to its fullest potential?

the 1150/1155 mb have 2 channel ram controller if you llok under your mb ram slots there an a1 and an a0 ram slots the a0 is one bank of two dimms the other banks is another bank with two dimms. the 2011 and other chipset had two quad channel ram slots one bank needed four dimms to run at it max rated speed not two.
