FAQ about Lenovo Thinkpad E485 RAM
How much RAM can I put in my E485?
You can install up to 32GB total. The laptop has 2 memory slots, so that's 16GB per slot maximum.
What type of RAM do I need for the E485?
You need DDR4 SODIMM modules - these are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR4, not DDR3 or DDR5.
What speed RAM should I get?
2400MHz is the recommended speed. You might see it listed as PC4-19200 - that's the same thing. Faster RAM will work but will just run at 2400MHz anyway.
Can I mix different RAM sizes?
Yeah, you can mix sizes like 8GB + 16GB. But for best performance, matching pairs (like 8GB + 8GB) work better since they can run in dual channel mode.
Do I need to remove the old RAM when upgrading?
Depends what's already in there. If both slots are full, you'll need to remove at least one stick. If there's an empty slot, you can just add to what's there.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM and 16GB or less per stick, it should work. Just avoid the low-voltage DDR4L unless you know your current RAM is also DDR4L - mixing types can cause issues.
