5 Things to Know Before Adding a Second RAM Stick

Dual-channel memory gives a real 10-20% performance boost in memory-sensitive tasks, making it worth the upgrade if you have a single stick.

Match the new stick to your existing one exactly: same speed, timings, voltage, and ideally the same brand and model to avoid issues.

If you cannot find an exact match, buy a 2x8GB kit instead and sell or repurpose your old stick.

Mixing different RAM sticks forces both to run at the slower stick’s speed and can cause instability, so it is not worth the small savings.

Check your motherboard manual and current RAM model first; if you can find an identical stick, buy one more. If not, go with a kit.
