Open the case of your laptop or desktop computer. Find the RAM module and make sure it is properly seated or connected to the slot. Once you have found the RAM slot, push down on the locking tabs from both ends to release it.

Make sure the RAM stick is aligned with the slot, making sure the notch of the RAM stick matches the notch of the slot. Make sure it is centered between the latches. Apply pressure to insert the RAM stick vertically until it clicks into place.
