Review on SAMSUNG 4GB DDR3 PC3-12800 1600MHz Laptop Memory Module RAM, 204-Pin SODIMM. Model M471B5273DH0-CK0 by Kenny Rossi

Works with my Toshiba Satellite L850. I had trouble getting it in the slot at first. After trying to plug it in for 15 minutes, I turned on the laptop and got a completely black screen. I then disassembled my two lamb sticks properly and used them correctly. You need to insert them into the slot at a 45 degree angle and then slide them into place until you hear a slight click. It's easy if you do it right, and if you have trouble, do it wrong, you don't have to force anything. After that, the laptop will work, the new memory will be identified. Satisfied with the price and service, I will buy again.
