FAQ about Asus U36JC RAM
How much RAM can I put in the Asus U36JC laptop?
Maximum is 4GB total. The laptop has 2 memory slots, so you could do 2x2GB modules or keep one original stick and add another.
What type of memory does the U36JC use?
It uses DDR3 SODIMM modules - that's the smaller laptop-sized RAM, not the full-size desktop sticks. Make sure you get SODIMM specifically.
What speed RAM should I get for the U36JC?
The recommended speed is 1066MHz (also labeled as PC3-8500). The system might accept faster RAM like 1333MHz, but it'll just run at 1066MHz anyway, so no point spending extra.
Can I mix different RAM sizes in the two slots?
Technically yes, like 1GB + 2GB, but it's better to use matching pairs (2GB + 2GB) for dual-channel performance. Mixing sizes still works but isn't optimal.
Is 4GB really the maximum or can I try putting in more?
4GB is the hard limit - the chipset won't recognize anything beyond that. Even if you install 8GB (2x4GB), the system will only see and use 4GB total.
