I have a new HP laptop and I want the fastest memory you can buy. I do not mind spending a couple hundred for the best. Right now I have 204pin SoDimm DDR3 PC12800 8Gb. And I want to go up to 2133 or higher. What would you recomend for me. I have another laptop and I picked out Corsair 1866 16Gb Sodimm and this memory actually ranked 8th in letency out of all the memory SiSoft Sandra ever tested EVER. But I did not shop around much. I also realize that Kingston makes a 2133 version but it is only 8Gb. I kind of wanted 16Gb. But I am willing to settle if it is the fastest. What is the best memory for a laptop? Simple question.
