FAQ about Lenovo Legion 17IMH05 RAM
How much RAM can I put in the Legion 17IMH05?
Maximum is 16GB total. The laptop has 2 memory slots, so you're looking at 2x8GB sticks max. Can't go higher than that even if you wanted to.
What type of RAM does this Legion laptop use?
It uses DDR4 SODIMM modules - that's the smaller laptop memory, not the full-size desktop sticks. Make sure you get SODIMMs or they won't fit.
What speed RAM should I get for the Legion 17IMH05?
Get 2666MHz (also labeled as PC4-21300). The system might accept faster RAM but it'll just run at 2666MHz anyway, so no point spending extra on faster speeds.
Can I mix different RAM sizes in the two slots?
Technically yes, like 8GB + 4GB, but you'll lose dual-channel performance which hurts gaming. Better to match them - either 2x4GB or 2x8GB for best performance.
Do I need to remove the old RAM when upgrading?
Depends what's already in there. If it came with 1x8GB and you want 16GB total, you'd add another 8GB stick. If it has 2x4GB and you want 16GB, you'll need to replace both with 2x8GB.
