To install a RAM module:

Gently slide the module into the slot.

Visually confirm that the notch between the module's gold contacts aligns with the receiving slot.

Firmly push both edges of the module to seat the RAM module into the slot.

As you push, do not bend or twist the RAM module.

As the module slides into position, the lock tabs along each edge should click back in place.

Make sure that both locking tabs rest securely in the RAM module's indents.
