FAQ about Lenovo ThinkPad T440s RAM
How many RAM slots does the T440s have and can I access both?
The T440s has 2 total RAM slots, but here's the catch - only 1 slot is actually accessible for upgrades. The other slot has soldered memory that's permanently attached to the motherboard, so you can't touch that one.
What's the maximum RAM I can have in my T440s?
You can get up to 12GB total. The soldered slot typically has 4GB that you're stuck with, and you can add up to 8GB in the accessible slot. So 4GB (soldered) + 8GB (upgradeable) = 12GB max.
What type of RAM do I need for the T440s?
You need DDR3 SODIMM modules - that's the smaller laptop-sized RAM, not the full-size desktop sticks. Make sure it's DDR3, not DDR4 or DDR5, as those won't work.
What speed RAM should I get?
Go for 1600MHz (also labeled as PC3-12800). The system might accept other speeds, but 1600MHz is what's recommended and will work best with the T440s.
Can I just add any 8GB DDR3 stick?
As long as it's DDR3 SODIMM at 1600MHz, you should be good. The T440s isn't too picky about brands. Just make sure it's laptop memory (SODIMM) and not desktop memory (DIMM).
Is it worth upgrading from 4GB to 12GB?
Definitely. Going from 4GB to 12GB is a huge jump - you'll notice much better multitasking, faster performance with multiple browser tabs, and less system slowdown. It's one of the best upgrades you can do for the T440s.
