FAQ about Lenovo ThinkPad T480 RAM
How much RAM can I put in a T480?
You can install up to 32GB total - that's 16GB in each of the two slots. Pretty solid for a laptop from that era.
What type of RAM does the T480 use?
It takes DDR4 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get SODIMMs or they won't fit.
What speed RAM should I get for my T480?
2400MHz is the recommended speed (also labeled as PC4-19200). You could technically use faster RAM but it'll just run at 2400MHz anyway, so save your money.
Can I mix different RAM sizes in my T480?
Yeah, you can mix sizes like 8GB + 16GB if you want. Just know that mixing might disable dual-channel mode which can slightly impact performance. For best results, use matching pairs.
Do I need to remove the battery before upgrading RAM?
On the T480 you've got both internal and external batteries. Remove the external one for sure, and disable the internal battery in BIOS before you start poking around inside. Safety first.
Is one RAM slot easier to access than the other?
One slot is right under the bottom cover - super easy. The other one is under the keyboard, which means more disassembly. If you're only adding one stick, use the easy-access slot first.
