So I own an Alienware 17r3 laptop that I purchased in summer 2016. I have had no problems(which is amazing from what I have read online) until about a week ago when my laptop blue screened. After taking it to get it looked at(I am a computer newb) I was told that one of my RAM cards wasn't working. I was told that Dell likes to use B-grade parts like these in their expensive laptops which has me infuriated because I have lost pretty much everything including my 250+ modded Skyrim game. Anyway, I was told that my laptop has two 16gb RAM cards and since there was still one working card left that I should be fine. However, I don't want to be just "fine", I want to make sure that this never happens again. So, aside from having an external backup from now on, I need two new RAM cards. The specs I was given are 16gb DDR4-2133 SODIMM. Can anyone shed some light on what brand/model would be the best performance/value? I have heard the brand Crucial thrown around the most but I have also heard that I should get DDR4-2400 instead of 2133? HELP!!!
