FAQ about Lenovo G40-70m RAM

How much RAM can I put in my Lenovo G40-70m?

You can install up to 16GB total. The laptop has 2 memory slots, so you could do 2x8GB sticks or keep one existing stick and add another.

What type of RAM does the G40-70m use?

It uses DDR3 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones. Make sure to get DDR3, not DDR4 or DDR5.

What speed RAM should I get for the G40-70m?

Go with 1600MHz (also labeled as PC3-12800). The system might accept other speeds but 1600MHz is what works best with this model.

Can I mix different RAM sizes in the two slots?

Yes, you can mix sizes like 4GB + 8GB, but for best performance try to match the capacity and speed of both sticks. Mismatched RAM still works but runs in single-channel mode instead of dual-channel.

Do I need to remove the existing RAM when upgrading?

Not necessarily. If there's only one stick installed, just add another to the empty slot. If both slots are full with smaller capacity sticks, you'll need to replace one or both.
