    Looks like DDR4 to me. Can you post a picture of the laptop model number/serial number sticker so we can confirm it's the R541UV?

DDR4 but I can't find much info that specific laptop, also looks like a lot of bad reviews, I'm going to assume its 3rd party.

Keep in mind it'll be SODIMMs DDR4 and you will have to take it apart either way to upgrade it..
