Review on 💻 Samsung 4GB RAM DDR4 PC4-2133P (PC4 17000) Laptop Notebook Memory M471A5143EB0-CPB - OEM: Boost Laptop Performance with Samsung's DDR4 4GB RAM by Ronald Howlett

I have an old Lenovo All-in-One (Intel 6th Gen) that only had a stick of Samsung 4GB DDR4 SODDIM 2133MHz RAM, which is exactly the same as this model. I could have gotten a few better, faster sets of RAM for dual-channel operation, but it got more expensive, and replacing an existing one meant having a RAM stick, and I just didn't want the hassle. So I just bought this particular model as well as the installed one. Now that I have 8GB in dual channel, you can definitely see a 4GB performance jump even in things like the Chrome web browser.
