FAQ about Lenovo Legion 15IMH05H RAM
How much RAM can I put in my Legion 15IMH05H?
You can install up to 32GB total - that's 16GB per slot since you've got 2 slots to work with.
What type of RAM do I need for this laptop?
You'll need DDR4 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop ones. Make sure they're DDR4, not DDR3 or DDR5.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is the recommended speed. You can technically install faster RAM, but it'll just run at 2666MHz anyway, so save your money.
Can I mix different RAM sizes?
Yeah, you can run 8GB + 16GB if you want 24GB total, but for best performance, matching sizes (like 16GB + 16GB) gives you dual-channel mode which is faster.
Do I need to remove the old RAM?
Depends what's already in there. If you've got 2x8GB and want 32GB, then yes, you'll need to replace both sticks with 2x16GB. Check what you have first.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM at 2666MHz or higher, you should be fine. Just stick to regular voltage (1.2V) modules, not the low voltage ones.
