Which RAM slot?
Which RAM slot?
Review the guide, as it often lists the recommended order for installation. Motherboards with four slots typically suggest starting with slot two, followed by slot four, and then proceeding to the remaining slots. I’m not sure what happens with dual-slot boards.
Your needs vary greatly based on your tasks. Having two identical RAM modules isn't always required.
With just a single stick, the slot it occupies doesn’t change much. It reads and writes consistently regardless of the tiny gap in electricity across a PCB.
