FAQ about Asus K43SD RAM
How much RAM can I put in my K43SD laptop?
Maximum is 8GB total. You've got 2 slots to work with, so that's 4GB per slot max.
What type of memory do I need for this laptop?
You need DDR3 SODIMM modules - the smaller laptop memory sticks. Make sure it's DDR3, not DDR4 or anything else.
What speed RAM should I get?
1333MHz (also labeled as PC3-10600) is what's recommended. Higher speeds will work but will just run at 1333MHz anyway, so save your money.
Can I mix different RAM sizes?
Yeah, you can do like 2GB + 4GB if you want. Just keep in mind mixing sizes means you won't get dual-channel performance benefits.
Do I need to match the RAM that's already installed?
Not strictly necessary, but matching the speed and timings helps avoid compatibility headaches. If you're replacing both sticks, just get a matched pair.
Will faster RAM like 1600MHz work?
It'll work fine, but it'll automatically downclock to 1333MHz to match what the laptop supports. No performance benefit, so stick with 1333MHz.
