FAQ about Lenovo IdeaPad 330-15ARR RAM
How much RAM can I add to my Lenovo 330-15ARR?
You can add up to 16GB in the single accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so maximum total is 20GB (4GB fixed + 16GB you add).
What type of RAM does the 330-15ARR use?
It uses DDR4 SODIMM modules - the smaller laptop-sized memory sticks. Make sure to get 2400MHz speed (also labeled as PC4-19200) for best compatibility.
Can I upgrade both RAM slots on this laptop?
No, only one slot is upgradeable. The other slot has 4GB permanently soldered to the motherboard, so you're stuck with that. You can only replace/upgrade the module in the accessible slot.
Will faster RAM like 2666MHz or 3200MHz work?
It'll probably work but will run at 2400MHz anyway since that's what the system supports. Save your money and just get 2400MHz RAM - there's no performance benefit to buying faster modules for this laptop.
What happens to my existing RAM when I upgrade?
You'll remove whatever's in the upgradeable slot and replace it with your new module. The 4GB soldered RAM always stays. So if you currently have 8GB total (4GB soldered + 4GB in slot), and you add a 16GB module, you'll end up with 20GB total.
