The laptop in which these memories were used is a turbo X with a 2nd generation i7. The previous memory was 8gb with 1333mhz. I can say that the difference was not noticeable at first, however, with the use of relatively demanding programs, the difference became apparent. I recommend them if you want to keep your laptop for another two years.

I bought it for the Gigabyte Brix GB-BPCE-3350C barebone (mini pc), and it worked, but it had problems starting up, probably due to incompatibility. Specifically, while the power led was on, it did nothing for a while. I had to manually turn it off by pressing the power on button for a long time. Then I would turn it on again, and usually on the 3rd or 4th try, it would start normally. From there on, it was okay. But there were compatibility issues during startup with this particular machine. The truth is that this specific memory is not on the lists recommended by the manufacturer, but usually there is no problem. However, in this case, there was, so I ended up buying the Silicon Power 8GB DDR3 RAM with Speed 1600 Code: SP008GLSTU160N02, which has a lower speed, but it works fine.
