FAQ about Lenovo G555 RAM
What kind of RAM does the Lenovo G555 use?
It uses DDR2 SDRAM in the SODIMM form factor - that's the smaller laptop-sized memory sticks, not the full-size desktop ones.
How much RAM can I put in a G555?
Maximum is 4GB total. You've got 2 slots to work with, so that's typically 2x2GB sticks.
What speed RAM should I get for the G555?
Look for 800MHz DDR2, also labeled as PC2-6400. Don't bother with faster speeds - the laptop won't use the extra speed anyway.
Can I just add one stick or do I need to buy a pair?
You can add just one stick if there's an empty slot. But for best performance, matching pairs are ideal since it enables dual-channel mode.
Will DDR3 memory work in the G555?
No, absolutely not. DDR2 and DDR3 are physically different and won't even fit in the slots. Stick with DDR2 only.
Is it worth maxing out to 4GB?
Depends what you're running. For basic tasks and older operating systems, 2-3GB might be enough. But 4GB gives you more breathing room and isn't that expensive for DDR2 these days.
