FAQ about Asus X550MJ RAM
How much RAM can I put in my X550MJ laptop?
Maximum is 8GB. It only has one memory slot, so you'll need to replace whatever's in there with a single 8GB stick.
What type of memory does the X550MJ use?
DDR3 SODIMM - that's the smaller laptop memory, not the full-size desktop RAM. Make sure you get DDR3, not DDR4 or DDR5.
What speed RAM should I get for the X550MJ?
1600MHz (also labeled as PC3-12800) is the recommended speed. The laptop might work with faster RAM but it'll just run at 1600MHz anyway, so save your money.
Can I add more RAM without removing the existing stick?
No, there's only one slot. You have to remove whatever's in there and replace it with your new stick. So if you have 4GB now and want 8GB, you need to buy an 8GB stick and take out the 4GB one.
Will any DDR3 laptop memory work?
As long as it's DDR3 SODIMM (the laptop size), it should work. Just stick with 1600MHz speed and 8GB or less. The 1.5V standard voltage DDR3 is what you want, not the low voltage DDR3L, though DDR3L usually works fine too.
