What type of RAM do I need for this laptop?
You need DDR4 SODIMM memory running at 2133MHz. Make sure it's laptop memory (SODIMM), not desktop RAM.
Can I upgrade both RAM slots?
No, only one slot is accessible for upgrades. The other has 4GB permanently soldered to the motherboard.
Will faster RAM like 2400MHz or 2666MHz work?
Yes, faster RAM will work but it'll run at 2133MHz to match the system's speed. No performance benefit from buying faster memory.
Is it worth upgrading from 4GB to 12GB?
