FAQ about Lenovo Legion 5 15ARH05H RAM
How many RAM slots does the Legion 5 15ARH05H have?
It has 2 memory slots total. Pretty standard for gaming laptops - gives you flexibility to either use both slots or leave one open for future upgrades.
What's the maximum RAM I can install?
The official max is 16GB total. That means either 2x8GB sticks or 1x16GB if you want to keep a slot free. Some users report success with more, but 16GB is what's officially supported.
What type of RAM do I need to buy?
You need DDR4 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop ones. Make sure it's DDR4, not DDR3 or DDR5.
What speed RAM should I get?
3200MHz (also labeled as PC4-25600) is the recommended speed. The system might accept faster RAM but it'll likely run at 3200MHz anyway, so no point spending extra on faster speeds.
Can I mix different RAM sizes or speeds?
Technically yes, but not ideal. If you mix speeds, everything runs at the slower speed. Mixing sizes works but you lose dual-channel benefits on the mismatched portion. Best to use identical sticks.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM at 3200MHz or slower, it should work fine. Laptop RAM is pretty standardized. Just avoid the low-voltage DDR4L unless you're sure it's compatible.
