# Carefully align the pins and push on the new CPU board. It is very important that you use both hands, pressing ONLY on all 4 corners evenly. Do not push on the center of the board and especially do not push on the area with the Olimex logo. Underneath the logo is the RAM chip which might be damaged if you press here.
