Review on 💻 Samsung 8GB DDR3 PC3L-12800 1600MHz Laptop RAM Memory Module - M471B1G73EB0-YK0 Original SODIMM by Steve Harris

This memory module helped update the Dell Inspiron 3521. The laptop was originally running OS 8.1 so 4GB of RAM was enough to keep the device from freezing. Unfortunately, 4GB of RAM is not enough in a Windows 10 environment. The addition of 8GB (for a total of 12GB) made the Inspiron 3521 much faster. Samsung memory is the same as factory installed. There are no problems with the detection by the system. I believe 16GB of RAM is the max for this model, so an additional upgrade is possible by replacing the original 4GB of RAM with an additional 8GB of RAM.
