FAQ about Lenovo Thinkpad Edge E545 RAM
How much RAM can I put in my Lenovo Edge E545?
You can install up to 16GB total. The laptop has 2 memory slots, so you could do 2x8GB sticks for the maximum.
What type of RAM does the E545 use?
It uses DDR3 SODIMM modules - the smaller laptop-sized memory sticks. Make sure you get DDR3, not DDR4 or DDR5, as they won't fit or work.
What speed RAM should I get for the E545?
Go with 1600MHz (also labeled as PC3-12800). The system might accept other speeds but 1600MHz is the recommended spec that'll work best.
Can I mix different RAM sizes in the E545?
Yes, you can mix sizes like 4GB + 8GB = 12GB total. But for best performance, matching pairs (like 8GB + 8GB) are ideal since they can run in dual-channel mode.
Do I need to remove existing RAM when upgrading?
Depends what's already installed. If both slots are full, you'll need to remove at least one stick. If you have one slot free, just add the new module there.
Is upgrading the RAM difficult on this model?
Not really - you'll need to remove the bottom panel to access the RAM slots. Just make sure the laptop is off, battery removed, and you're grounded to avoid static damage.
