FAQ about Asus U45Jc RAM
How many RAM slots does the Asus U45Jc have?
It has 4 memory slots total, which is pretty generous for a laptop from that era. Most similar laptops only had 2 slots, so you've got more flexibility for upgrades.
What's the maximum RAM I can install?
The system tops out at 8GB total. That means with 4 slots, you could do 4x2GB sticks, or leave some slots empty and use larger modules in just 2 slots.
What type of RAM do I need to buy?
You need DDR3 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop RAM. Make sure it's DDR3, not DDR2 or DDR4, as they're not compatible.
What speed RAM should I get?
The recommended speed is 1333MHz (also labeled as PC3-10600). You can sometimes use faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so save your money and stick with 1333MHz modules.
Can I mix different RAM sizes?
Yes, you can mix sizes like 2GB + 4GB, but for best performance, try to match pairs in dual-channel configuration. If you're using all 4 slots, ideally use 4 identical sticks or at least 2 matching pairs.
Do I need to buy RAM in pairs?
Not required, but recommended. The laptop will work with a single stick or mismatched sizes, but you'll get better performance with matched pairs running in dual-channel mode.
