I bought my PC to this RAM upgrade me to 16GB. Was concerned at first, because the already eingebauen RAM modules are the model HyperX blue. When I then checked what's the difference between my already built-in Blu (KHX1600C9D3B1 / 4G) and this Savage (on the HP of Kngston) I saw that there is no difference of the technical specifications here, not at all. Therefore, I have then bought these Savage yet, and the PC is running without any problems and also utilizes the full memory. Obviously, these are only a visual difference compared to the Blu-variant. I am really quite satisfied. Now must ise just keep "forever" ;-)
