SAMSUNGOriginal 8GB (1 x 8GB) 204-pin SODIMM, DDR3 PC3L-12800, 1600MHz ram Memory Module for laptops (M471B1G73EB0-YK0)

This originally did not work when installed. The keyboard would flash intermittently and the computer would not boot up. However, I found a solution online that worked. If you unplug the battery, then install the RAM stick, plug the battery back in, your computer will boot up. It took me three different installations with the same no-boot result before I found the workaround. Hope this helps if you have the same problem I did.

valuable and works well.

Upgraded a laptop to 16gb ram. Laptop ran a bit quicker. I later replaced HDD with SDD and made a HUGE difference.It was easy for me to install, I do this type of stuff all the time.

Unplug and plug in new works great so far seems to be doing what it should

Works

This product is exactly what it says it is.

This memory module helped refresh a Dell Inspiron 3521. Originally, the laptop OS was 8.1, which the 4GB of RAM was sufficient to keep the unit from bogging down. Unfortunately, in the Windows 10 environment, 4GB of RAM in inadequate.The addition of 8 GB (total of 12 GB) made the Inspiron 3521 much faster. The Samsung memory is the same as the factory installed. No issues with the system recognizing it. I believe that 16 GB of RAM is the max for this model, so an additional upgrade is possible by replacing the original 4 GB RAM with another 8 GB of RAM.
