FAQ about Lenovo ThinkPad T480s RAM
How much RAM can I add to my T480s?
You can add up to 16GB in the single accessible slot. The laptop has 8GB soldered that can't be changed, so maximum total is 24GB.
What type of RAM does the T480s use?
It uses DDR4 SODIMM modules - the smaller laptop memory sticks. Make sure to get 2400MHz speed for best performance.
Can I upgrade both RAM slots?
No, only one slot is upgradeable. The other has 8GB permanently soldered to the motherboard.
What happens if I use faster RAM like 2666MHz?
It'll work but will automatically slow down to match the 2400MHz speed the system supports. No harm done, just won't get the extra speed.
Is upgrading the RAM difficult?
Pretty straightforward - remove the bottom panel, find the empty slot next to the soldered memory, insert the new stick at an angle and press down until it clicks.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM and 16GB or less, it should work. Stick with 2400MHz for guaranteed compatibility.
