Hello everyone ! need help :)
I have ASUS X550DP Notebook. Currently installed Samsung 4GB 1600MHz (M471B5273CH0-YK0). I want to add one more 2GB stick to another empty slot.
So, searching the internet I found this one Samsung 2GB 1600 MHz (M471B5773DH0-YK0).
need help regarding compatibility, can I use these 2 stick together ?
Thanks in advance :D sorry for bad English.
