FAQ about Asus X454LJ RAM
How much RAM can I add to my Asus X454LJ laptop?
You can add up to 8GB in the single accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so with an 8GB stick installed, you'll have 12GB total.
What type of RAM does the X454LJ use?
It uses DDR3 SODIMM modules - the smaller laptop memory sticks. Make sure to get DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I buy for this laptop?
Get 1600MHz DDR3 (also labeled as PC3-12800). The laptop will work with slower speeds like 1333MHz, but 1600MHz is the recommended speed for best performance.
Can I upgrade both RAM slots on the X454LJ?
No, only one slot is accessible for upgrades. The other slot has 4GB permanently soldered to the motherboard, so you're stuck with that 4GB base amount.
Will a 16GB stick work to get more than 12GB total?
No, the laptop's maximum is 12GB total. Even if you install a 16GB stick, the system will only recognize 8GB of it, giving you 12GB when combined with the built-in 4GB.
