FAQ about Asus K40IP RAM
How much RAM can I put in my K40IP laptop?
Maximum is 8GB total. You've got 2 slots, so that's 4GB per slot max.
What type of memory does the K40IP use?
It uses DDR2 SODIMM - the smaller laptop memory sticks, not the full-size desktop ones.
What speed RAM should I get for the K40IP?
800MHz DDR2 (also called PC2-6400). Slower speeds will work but why bottleneck yourself? Faster won't help - the system can't use it.
Can I mix different RAM sizes in the K40IP?
Yeah, you can do like 2GB + 4GB if you want. Just keep both sticks at 800MHz DDR2 SODIMM.
Will DDR3 work in my K40IP?
Nope, DDR2 only. DDR3 won't even fit in the slots - different notch position.
Is it worth maxing out to 8GB on this old laptop?
Depends what you're doing. For basic stuff 4GB is probably fine. But DDR2 is getting harder to find and more expensive, so consider if it's worth investing in old tech.
