Asus X59GL - RAM Upgrade Guide

The Asus X59GL laptop has two slots available for memory upgrades, allowing for a maximum memory capacity of 4GB. It uses DDR2 SDRAM as the memory type, which comes in a SODIMM form factor, designed specifically for smaller devices like laptops. For optimal performance, the memory should operate at a clock speed of 800MHz, often labeled as PC2-6400.

FAQ about Asus X59GL RAM
How much RAM can I put in my X59GL laptop?
Maximum is 4GB total. You've got 2 slots to work with, so that's 2GB per slot if you max it out.
What type of memory do I need for this laptop?
You need DDR2 SODIMM modules - the smaller laptop-sized sticks, not the full desktop ones. Make sure it's DDR2, not DDR3 or anything newer.
What speed RAM should I get?
800MHz (also labeled as PC2-6400) is what's recommended. You might find 667MHz modules work too, but 800MHz is the sweet spot for this system.
Can I mix different RAM sizes?
Yeah, you can do like 1GB + 2GB if you want 3GB total. Just keep in mind mixing sizes means you won't get dual-channel performance, but it'll still work fine.
Will faster RAM like 1066MHz work?
It'll probably work but will just run at 800MHz anyway. The system will downclock it to match what it can handle, so you're basically wasting money on the faster speed.
Do I need to match the existing RAM exactly?
Not really necessary as long as it's DDR2 SODIMM. Different brands usually play nice together. If you're paranoid about compatibility, matching specs is safer but not required.
