FAQ about Asus X45C RAM
How many memory slots does the Asus X45C have?
It has 2 total memory slots, but here's the catch - only 1 slot is actually accessible for upgrades. The other slot has memory soldered directly to the motherboard, so you can't touch that one.
What's the maximum RAM I can have in my X45C?
The laptop maxes out at 8GB total. Since one slot isn't upgradeable, you can only add up to 4GB in the accessible slot. So if your laptop came with 4GB soldered, adding another 4GB stick gets you to the 8GB maximum.
What type of RAM do I need for this laptop?
You need DDR3 SODIMM memory - that's the smaller laptop-sized RAM, not the full-size desktop sticks. Make sure it's DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I get?
Go with 1333MHz (also labeled as PC3-10600). The laptop might work with faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so save your money and stick with the recommended speed.
Can I upgrade both RAM slots?
Nope, only one slot is upgradeable. The other has memory permanently attached to the motherboard. This is pretty common in budget laptops to save costs.
Will any DDR3 SODIMM work?
As long as it's DDR3 SODIMM at 1333MHz or higher, you should be fine. Just remember the 4GB limit for the upgradeable slot. Double-check the voltage too - standard 1.5V DDR3 is what you want.
