FAQ about Asus X45A RAM
How much RAM can I put in my X45A laptop?
Maximum is 4GB. It only has one memory slot, so you'll need to replace whatever's in there with a single 4GB stick.
What type of memory does the X45A use?
DDR3 SODIMM - that's the smaller laptop memory, not the full-size desktop RAM. Make sure you get SODIMM specifically.
What speed RAM should I get for the X45A?
1333MHz (also labeled as PC3-10600). The laptop might accept faster RAM, but it'll just run at 1333MHz anyway, so no point paying extra for faster speeds.
Can I add more RAM without removing the existing stick?
No, there's only one slot. Whatever memory is currently installed needs to come out first, then you put in the new stick.
Is 4GB enough for basic use?
For web browsing, office work, and light tasks it's manageable. Modern Windows will use most of it just running, so don't expect to multitask heavily. It's the absolute minimum I'd recommend these days.
Why can't I upgrade past 4GB?
Hardware limitation - the motherboard and chipset simply don't support more than 4GB. Pretty common for budget laptops from that era.
