This may be a silly question because I'm not fully sure how RAM works and is loaded, however I'm trying to figure out a potential configuration here.
I have two RAM sticks that are both spec matched for my MBP. One of them is a 8gb gskill stick, and the other is a 4gb Samsung stick. I rarely use more than 8gb of RAM, however it does happen on occasion.
I would think that it would be best for me to fill the entire 8GB stick first, and then load data onto the 4GB stick if the 8 overflows. This said, I'm not sure if it's possible to load the sticks "one and then the other" like this, or if it would be beneficial.
Is the order that info is loaded into RAM determined by the slot that the stick is in? If so, which slot (top or bottom) should I stick my 8GB stick into in order to make sure that it's used before the 4gb stick?
