Memory
Up to 64GB of DDR4 (2133 MHz) SO-DIMM memory is possible (four 16GB modules, two upgradeable by the user). Before handling memory, know that it is most susceptible to static electricity, wear a anti-static wristband or at least discharge yourself first. Below you can see two free slots, one is stacked on top of the other so make sure you install the bottom module first. Align the pins to make sure you have the module the right way up, insert the memory into the slot angled at about 30°, use your thumbs and press evenly on both sides to make sure the module goes all the way into the slot, finally, push the top of the module down towards the motherboard until both of the locks on the sides click into place. Repeat the process for the other module.
