I have single Kingston 4 GB DDR3 RAM of 1333 MHz. Suppose, I want to make the RAM up to 8 GB, but I have two other Kingston 2 GB DDR3 RAM of 1333 MHz. Please note that the 2x2 GB RAM and the single RAM are equal in all respects except the RAM size. I fit them in two other RAM slots, keeping the other RAM slot dual to the 4 GB one empty. Would the PC show as 8 GB RAM?
