FAQ about Lenovo V155-15API RAM
How many RAM slots does the V155-15API have?
There are 2 total slots, but only 1 is accessible for upgrades. The other slot has soldered memory that can't be removed.
What's the maximum RAM I can have in this laptop?
Maximum is 20GB total. Since one slot has fixed memory (likely 4GB), you can add up to 16GB in the accessible slot to reach that 20GB maximum.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory - that's the smaller laptop-sized RAM, not the full-size desktop kind. Make sure it's DDR4, not DDR3 or DDR5.
What speed RAM should I get?
2666MHz (also labeled as PC4-21300) is the recommended speed. You can use faster RAM but it'll just run at 2666MHz anyway, so no point paying extra for faster speeds.
Can I upgrade both RAM slots?
No, only one slot can be upgraded. The other has memory permanently attached to the motherboard. This is pretty common in budget laptops to save costs.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM and ideally 2666MHz, it should work. Stick to standard voltage (1.2V) modules. Higher capacity single sticks (like 16GB) are better than trying to mess with the non-upgradeable slot.
