My system information says installed RAM 24.0GB (16.0GB usable). My GPU device properties show 8GB of Shared System Memory. My task manager under the performance tab shows 8.0GB hardware reserved. I am assuming the device properties and task manager are referring to the same 8GB of memory, and that this 8GB of memory is what is missing as "usable" in my system information. So my question(s) are, is this actually "shared" and is my computer actually able to "use" this as it only says 16GB is usable according to my system information? Second question, why would my system ever show all 24GB available because I seem to remember a time before that I never had parenthesis of usable RAM, I had the full amount (and it showed the full amount with the same hardware configuration I have now, I haven't made changes to the hardware in years, is it a Windows 10 thing?)
