16GB vs 32GB RAM sticks: Mixing works but matched pairs are better

You can mix 16GB and 32GB sticks for 48GB total, but performance takes a small hit in memory-sensitive tasks like gaming or video editing because the system runs in flex mode — first 16GB dual channel, remaining 16GB single channel. Stability is the bigger issue: mixing brands, speeds, or timings can cause crashes, so only do it if you already own both sticks. If buying new, get a matching pair — the headache isn’t worth saving twenty bucks.
