FAQ about Asus X407UB RAM
How many RAM slots does the Asus X407UB have?
Just one slot total. It's a single-slot system, so whatever you install is all you get - no adding a second stick later.
What's the maximum RAM I can put in this laptop?
You can go up to 16GB. That's the ceiling for this model.
What type of RAM do I need for the X407UB?
You need DDR4 SODIMM - that's the smaller laptop-sized memory stick, not the full-size desktop RAM.
What speed RAM should I get?
2666MHz is the recommended speed. You might see it listed as PC4-21300 - same thing, just different naming convention.
Can I use faster RAM like 3200MHz?
You can install it, but it'll just run at 2666MHz anyway. The system will downclock it to match what it supports, so you'd be wasting money on the extra speed.
Is the RAM soldered or removable?
It's removable since it uses SODIMM slots. If it was soldered, you'd be stuck with whatever came from the factory.
Will any DDR4 SODIMM work?
As long as it's DDR4 SODIMM and 16GB or less, you should be fine. Just stick to reputable memory manufacturers to avoid compatibility headaches.
