FAQ about Asus X455LA RAM
Can I upgrade the RAM in my X455LA laptop?
Yes, but only partially. The laptop has 2 memory slots total, but only 1 is accessible for upgrades. The other slot has soldered memory that can't be changed.
What's the maximum RAM I can have in this laptop?
The maximum total RAM is 12GB. This typically means 4GB soldered on the motherboard plus up to 8GB in the upgradeable slot.
What type of RAM do I need to buy?
You need DDR3 SODIMM memory modules. Make sure it's SODIMM (the smaller laptop memory) not regular desktop RAM.
What speed RAM should I get?
1600MHz is the recommended speed, also known as PC3-12800. The laptop might work with different speeds but 1600MHz is the sweet spot.
Can I just add another 8GB stick to what's already there?
It depends on what's currently in the upgradeable slot. If it's empty, yes. If there's already a smaller module there, you'll need to replace it with the 8GB stick.
Why can't I upgrade both RAM slots?
One slot has RAM soldered directly to the motherboard. This is common in thin laptops to save space but means that memory is permanent.
