Asus U35Jc - RAM Upgrade Guide

The Asus U35Jc laptop has two memory slots available for RAM upgrades. It can support a maximum of 8GB of memory. The type of RAM used is DDR3 SDRAM, and it comes in a SODIMM format, which is a smaller type of memory module designed for laptops. For optimal performance, the recommended clock speed for the RAM is 1333MHz, also referred to as PC3-10600.

FAQ about Asus U35Jc RAM
How much RAM can I put in my U35Jc laptop?
You can install up to 8GB total. The laptop has 2 memory slots, so you could do 2x4GB sticks or one 8GB stick if you want to leave a slot open for future upgrades.
What kind of memory do I need for the U35Jc?
You need DDR3 SODIMM modules - the smaller laptop-sized sticks, not the full-size desktop ones. Make sure to get DDR3, not DDR4 or DDR5, as they're not compatible.
What speed RAM should I get?
Get 1333MHz (also labeled as PC3-10600). The laptop might work with faster RAM like 1600MHz, but it'll just run at 1333MHz anyway, so there's no benefit to buying faster memory.
Can I mix different RAM sizes or do they need to match?
You can mix sizes like 2GB + 4GB, but for best performance, matching pairs (like 4GB + 4GB) are ideal since they can run in dual-channel mode. Mixing works fine though if you already have one stick you want to keep.
Do I need to worry about voltage or CAS latency?
Standard DDR3 SODIMM at 1.5V will work fine. Don't get the low-voltage DDR3L unless you want the compatibility - regular DDR3 is usually cheaper. CAS latency doesn't matter much at 1333MHz, anything from CL9 to CL11 is fine.
