I have 4GB of RAM installed. According to the "System" section of the control panel, 2.3 GB of the 4 GB is usable.
I tried adjusting msconfig.exe, but it made no difference. I changed the "dedicated graphic memory" from 128 to 64 MB in my BIOS, now my system can use 2.36 GB of RAM. Shouldn't Windows 7 32-bit be able to use 3-3.5 GB of RAM?
I'm using an Acer Travelmate 8572 laptop.
Edit: Could it be because of my Intel HD Graphics?
