cyber bro but i can't understand whats your point. What is your point. Please clarifiy
lets say that having two sticks is like having two cores. Instead of pushing all the data to one RAM, the processor can share the data between two modules. So, instead of using a single 64-bit data channel, the CPU gets to use two 64-bit data channels increasing data throughput resulting in better performance.
The difference may not be visible with apps that processor tiny amounts of data but is very much visible when large amount of data is being processed like video encoding etc.
