This gives you the same capacity but greater bandwidth since the memory uses two slots, which makes for better performance.

On the other hand, a gaming PC often has four slots for running two pairs of dual-channel memory. If upgrading your laptop shipped with 8GB RAM, you may need a 16GB SODIMM stick because there's only one available slot.
