Two 16GB sticks vs four 8GB sticks: Two sticks win for stability and upgradeability

Two 16GB sticks are the smarter choice for almost everyone. Four sticks put more stress on the memory controller, causing stability issues and trouble hitting rated speeds, while two sticks just work. You also leave two slots open for an easy upgrade to 64GB later. Four sticks only have an edge in aesthetics or niche workloads that benefit from more ranks, but that’s rare and not worth the headache.
