FAQ about Lenovo Thinkpad E550 RAM
How much RAM can I put in my E550?
You can go up to 16GB total. The laptop has 2 slots, so that's 8GB per slot maximum.
What kind of memory do I need for this laptop?
You need DDR3 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop ones. Make sure it's DDR3, not DDR4 or DDR5.
What speed RAM should I get?
1600MHz (also labeled as PC3-12800) is what you want. The system might accept other speeds but 1600MHz is the sweet spot for this model.
Can I mix different RAM sizes?
Yeah, you can do like 4GB + 8GB if you want. It'll work fine, though matching sizes (like 8GB + 8GB) is ideal for dual-channel performance.
Do I need to remove the old RAM first?
Depends what's already in there. If both slots are full, you'll need to remove at least one stick. If you've got one empty slot, just pop in the new stick.
Is it hard to install the RAM myself?
Not really - usually just remove a panel on the bottom, angle the RAM stick in at about 45 degrees, push down until it clicks. Takes maybe 5 minutes if you've never done it before.
