Which Ram to buy 4GB?

It's DDR3 on 800 MHz or DDR3 on 1600 MT/s (double data rate of 800) .Read on the stick and tell me the frequency on MHz.It is pretty risky to buy additional RAM because it can cause incompatibilities with the other stick. Also tell the model and the Manufacturer of your stick
 
Hello Gursimran Singh Bharaj,
please post here:
A. your laptop model
B. full system specifications of your laptop

We know it's acer, but some laptop brands can't even be upgraded to 8GB memory.

All best,
