Question 1

Is this compatible with the acer v5 touch you sell http://www.newegg.com/Product/Product.aspx?Item=N82E16834314096. If so, can I upgrade to 8gb or higher or is this the maximum amount?

Accepted Answer

use two tools 
1st go to crucial dot com and use there memory identification tool, that will tell you what your machine currently has. take special notice to the speed of the memory.

2nd use the newegg laptop memory configurator tool to see what is available for your machine. make sure when you order you match the speed from step one.

good luck

Question 2

Will this Ram stick work in my Toshiba Satellite C55D-A5344 ? I already have a 4GB stick of RAM in my Toshiba Satellite C55D-A5344. Will this work?

Accepted Answer

if the type  (DDR3) and speed (1600) match i don't see why it would not work
just make sure the speeds on your original ram and this one are as close as possible
