FAQ about Asus X405UR RAM
How much RAM can I add to my laptop?
You can add up to 8GB in the single accessible slot. The laptop has 2 slots total but only 1 can be upgraded - the other is soldered to the motherboard.
What type of RAM do I need to buy?
You need DDR4 SODIMM (the smaller laptop RAM sticks). Make sure it's 2133MHz speed, also called PC4-17000. Don't get desktop RAM by mistake - it won't fit.
Can I upgrade to 16GB total?
Yes, but it depends on what's already installed. If there's 8GB soldered on the motherboard, adding another 8GB stick will get you to 16GB total. Check your current configuration first.
Will faster RAM work if I can only find 2400MHz or higher?
Yes, faster RAM will work but it'll run at 2133MHz to match the system's speed. No point paying extra for speed you can't use though.
Is it difficult to install the RAM myself?
Not really - you'll need to remove the bottom panel, find the empty slot, and click the RAM in at an angle. Just be careful with static electricity and don't force anything. Plenty of video guides online if you're nervous.
