FAQ about Lenovo Thinkpad Edge E445 RAM
How much RAM can I put in my E445?
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 memory does the E445 use?
It uses DDR3 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get SODIMMs, not regular DIMMs.
What speed RAM should I get for the E445?
Get 1600MHz DDR3 (also called PC3-12800). The system might work with faster RAM but it'll just run at 1600MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the E445?
Yes, you can mix sizes like 4GB + 8GB to get 12GB total. 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 installed. If you have 2x4GB and want 16GB, you'll need to remove both and replace with 2x8GB. If you only have one stick installed, you might just add a second one.
