My motherboard has 4 memory slots, divided into two channels. In my motherboard's manual it is recommended that you use slots A2 and B2 before A1 and B1, as you can see in the image below. But why is this recommended? Running two RAM modules in A1 and B1 seems to work fine, so why is it recommended to use A2 and B2 first?
EDIT: The motherboard uses an Intel Z97 Express chipset.

That is probably because those two slots are used for dual channel operation.
