FAQ about Lenovo IdeaPad 330S-15IKB RAM
How many RAM slots does this laptop have and can I upgrade both?
It has 2 total RAM slots, but only 1 is accessible for upgrades. The other slot has 4GB soldered directly to the motherboard, so you can't remove or replace it.
What's the maximum RAM I can have in this laptop?
You can have up to 20GB total - that's the fixed 4GB on the motherboard plus up to 16GB in the upgradeable slot.
What type of RAM do I need to buy?
You need DDR4 SODIMM memory modules. Make sure it's SODIMM (the smaller laptop memory) not regular desktop DIMM.
What speed RAM should I get?
Look for 2400MHz DDR4 memory, also labeled as PC4-19200. The laptop should work with faster RAM too, but it'll just run at 2400MHz anyway.
Can I mix different RAM sizes or speeds?
Since you already have 4GB soldered on, you can add 4GB, 8GB, or 16GB in the open slot. Different sizes will work fine. If you use faster RAM, it'll just slow down to match the 2400MHz speed.
What RAM configurations make the most sense?
Adding an 8GB stick gives you 12GB total, which is good for most tasks. Adding 16GB gives you the maximum 20GB if you do heavy multitasking or content creation.
