FAQ about Lenovo Thinkpad Edge E220 RAM
How much RAM can I put in my Lenovo Edge E220?
Maximum is 8GB total. You've got 2 slots, so that's 4GB per slot max.
What type of memory does the E220 use?
DDR3 SODIMM - the smaller laptop memory sticks, not the full-size desktop ones.
What speed RAM should I get?
1333MHz (also labeled as PC3-10600). Faster RAM will work but will just run at 1333MHz anyway.
Can I mix different size memory sticks?
Yeah, like 2GB + 4GB works fine. But matching pairs (like 4GB + 4GB) gives you dual channel which is a bit faster.
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 to upgrade.
Is it hard to install?
Pretty easy - usually just need to remove a panel on the bottom, pop out old RAM if needed, and click in the new ones at an angle.
