I have a HP Pavilion 15 Gaming Laptop. It has 1 8gb RAM in and I recently added another following the instructions from some YouTube video.
The laptop doesn't seem to recognise it though. I have been looking at what I bought, the laptop had 1 8GB DDR3 RAM in it and I bought another 8GB DDR3L RAM. Is the one I bought not compatible or have I done something wrong?
