FAQ about Asus X58 RAM
How much RAM can I put in my Asus X58?
You can install up to 4GB total. The laptop has 2 memory slots, so you could do 2x2GB sticks or keep one original stick and add another.
What type of memory does the X58 use?
It uses DDR2 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure you get DDR2, not DDR3 or DDR4, as they won't fit.
What speed RAM should I buy?
Look for 800MHz DDR2 (also labeled as PC2-6400). The system might accept slightly different speeds, but 800MHz is what's recommended and will work best.
Can I mix different size memory sticks?
Yes, you can mix sizes like 1GB + 2GB, but for best performance, matching pairs (like 2GB + 2GB) usually work better. The system will run in single-channel mode with mismatched sticks.
Will faster RAM make a difference?
Not really - even if you install faster DDR2 (like 1066MHz), the system will downclock it to 800MHz anyway. Save your money and stick with the recommended speed.
