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?

Cheers Dave

  • Please give the exact type descriptions (they are written on the label of the module) of the installed DDR3 module and the new, bought DDR3 module and add this information via an edit to the question. This information is crucial in estimating your current situation. – zx485 Nov 30 '19 at 16:24
  • Most often than not, computers that use DDR3 (1,5Volts) won't work with DDR3L (1,35V). – user931000 Nov 30 '19 at 18:38
