  Why is my device not utilizing all of its available RAM?  




I have new problem with my Novo 7 Basic, Android 3.2, 8GB, 512 MB** RAM: 

When I go into Tools -&gt; System Info (have CPU, Display, Memory...) in Memory Info: 


Total Mem 343.MB + Free Mem   36.048 MB (&lt;512 MB RAM) 
Inactive     94.496 MB  


When I used : "Android Assitant app ", it shows my Memory info (RAM) is:


Used : 183,96MB 
Free:  150,95MB 


Total: 334.96 MB

"RAM Manager Free software ", it says that Memory info is:


MemTotal: 343.000 MB &amp; MemFree: 7012 kB


But my tablet is supposed to have 512 MB of RAM. Please explain this to me (for any problems or errors). How do I activate the "inactive mem 94.496 MB"?
This memory is not inactive. It is reserved for the GPU and the radios (wi-fi, bluetooth etc.) 

You cannot activate it because it's already in use.
