Two 16GB sticks vs four 8GB sticks: Two sticks is almost always better for stability and performance

Two 16GB sticks is simpler and more reliable than four 8GB sticks. Four sticks adds electrical load on the memory controller, often limiting overclocking and requiring looser timings. Two dual-rank sticks can even outperform four single-rank sticks. Only go with four if you’re adding to existing 8GB sticks; otherwise, buy the two-stick kit.
