FAQ about Lenovo Thinkpad Edge E220s RAM
How many RAM slots does the Lenovo Edge E220s have?
Just one slot total. That's it - no room for adding a second stick alongside the existing one.
What's the maximum RAM I can put in the E220s?
4GB is the absolute max. Even if you find an 8GB stick that physically fits, the system won't recognize more than 4GB.
What type of RAM does the E220s use?
It takes DDR3 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop RAM. Make sure you get DDR3, not DDR3L or DDR4.
What speed RAM should I get for the E220s?
1333MHz (also labeled as PC3-10600) is the recommended speed. You can technically use faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so save your money.
Can I add RAM without removing the existing stick?
Nope, single slot means you have to remove whatever's in there to upgrade. If you've got 2GB now and want 4GB, you need to buy a 4GB stick and swap them out.
Is upgrading to 4GB worth it on this laptop?
If you're currently running 2GB or less, absolutely. The jump to 4GB makes a noticeable difference for basic multitasking and web browsing. Just don't expect miracles - it's still an older system.
