Hi
I added two memory modules of 4Gb to my laptop acer 5253
To my surprise, windows only uses half of it.
I would like to use all of the RAM installed but I can not.
I'm on Windows 8.1 64 Bits (sorry if this picture is in french)

My computer (Acer 5253) supports 8Gb of RAM (http://acer.custhelp.com/app/answers/detail/a_id/15801/~/how-do-i-replace-the-ram-memory-on-my-acer-aspire-5253-series-notebook%3F#_ga=1.96281364.900584224.1484791719)

(reconnecting, alternating) the memory modules doesn't work.
Can you help me ?

Solution
Problem Solved!
- a faulty memory module
They were in their packaging and were new. I don't understand why but Im happy to have found the problem.

I tested the memory modules one by one and the computer didn't want to start with one of the two memory modules.
