FAQ about Asus X58C RAM
How much RAM can I put in this laptop?
Maximum is 4GB total. You've got 2 slots, so that's 2GB per slot max.
What kind of memory do I need to buy?
You need DDR2 SODIMM modules. Make sure it's SODIMM (the smaller laptop memory) not regular desktop RAM.
What speed RAM should I get?
800MHz is what's recommended, also called PC2-6400. You might find slower speeds work too, but 800MHz is the sweet spot.
Can I mix different RAM sizes?
Yeah, you can do like 1GB + 2GB if you want. Just remember the total can't exceed 4GB, and mixing sizes might disable dual-channel mode which can affect performance a bit.
Will DDR3 work instead of DDR2?
Nope, DDR3 won't even fit in the slots. It's DDR2 only - they have different notches so you can't physically install the wrong type.
Do I need to match the existing RAM exactly?
Not exactly, but try to match the speed (800MHz) at least. Different brands usually work fine together as long as the specs are similar.
