Hi,
My laptop has 8GB RAM. I would like to add 8GB more as it has space for a second stick.
The installed memory is : SODIMM DDR3 Samsung 8GB 2RX8 PC3L - 12800S-11-13-F3 (M471B1G73QH0-YK0)
.
I found the following memory: SODIMM DDR3 Samsung 8GB 2RX8 PC3L - 12800S-11-13-F3 (M471B1G73EB0-YK0)

Will they be compatible?
