Should I buy two 16GB RAM sticks or one 32GB stick?

Two 16GB sticks are usually the better buy if your motherboard has four slots. They enable dual-channel memory, boosting performance 5–15% in games and memory-sensitive tasks, while a single stick leaves that speed on the table. Cost-wise, a single 32GB stick is often $5–10 more, so you’re not saving money. Only buy one 32GB stick if you plan to upgrade to 64GB later and have only two slots.
