FAQ about Asus X51R RAM
How much RAM can I put in my Asus X51R laptop?
Maximum is 2GB total. You've got 2 slots to work with, so that's typically 2x1GB sticks or 1x2GB if you want to leave a slot open.
What type of memory does the X51R use?
It takes DDR2 SODIMM modules - the smaller laptop memory sticks. Make sure you get DDR2, not DDR3 or anything else, they're not compatible.
What speed RAM should I get for the X51R?
667MHz (PC2-5300) is what's recommended. You might find 800MHz sticks work but they'll just run at 667MHz anyway, so no point paying extra.
Can I mix different RAM sizes in the X51R?
Technically yes, like 1GB + 512MB, but it's better to match them. Same size, same speed, ideally same brand for best stability.
Is 2GB really the max for this laptop?
Yeah, that's the chipset limitation. Even if you somehow found 2GB SODIMMs and put two in, the system won't recognize more than 2GB total. Pretty typical for laptops from that era.
