FAQ about Lenovo G455 RAM
How much RAM can I put in my Lenovo G455?
The maximum is 4GB total. You've got 2 memory slots, so you could do 2GB in each slot or just upgrade one slot if you want to save money.
What type of RAM does the G455 use?
It uses DDR2 SODIMM modules. SODIMM is the smaller laptop version of RAM sticks, and DDR2 is the older generation - not DDR3 or DDR4 that newer laptops use.
What speed RAM should I get for my G455?
Look for 800MHz (also called PC2-6400). This is the recommended speed that'll work best with your system without causing compatibility issues.
Can I mix different RAM sizes in the two slots?
Yeah, you can mix them. Like you could put a 2GB stick in one slot and 1GB in the other for 3GB total. Just make sure they're both DDR2 SODIMM at 800MHz.
Do I need to remove the existing RAM to upgrade?
Depends on what's already in there. If you have two 1GB sticks and want to max out at 4GB, you'd need to replace both with 2GB sticks. Check what you currently have first.
Will faster RAM work in my G455?
Faster DDR2 RAM will usually work but it'll just run at 800MHz anyway. You're paying extra for speed you can't use, so stick with 800MHz unless you find a better deal on faster stuff.
