I upgraded this laptop http://www.acer.ca/ac/en/CA/content/model/NX.G2KAA.004 from 8gb of RAM to 16 GB of RAM. Windows performance monitor is showing me that of the 16gb installed 9.66 is being used for hardware and the rest is availible for my system.
I have tried msconfig > Boot > Advanced Options > Uncheck/Check maximum RAM. I have also tried the RAM in a different computer. I have also run a memtest and only 8gb of the RAM was shown on the screen. How do I get back the ~9gb of RAM?
