FAQ about Lenovo IdeaPad 330S-14AST RAM

What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop-sized modules). Make sure it's 2133MHz speed, also known as PC4-17000.

One slot has the RAM soldered directly onto the motherboard. This is common in thin laptops to save space, but it means you can't remove or replace that memory.

It'll work but will automatically slow down to 2133MHz to match the system's specifications. No point spending extra on faster memory.
