I'm running Windows 10 64-bit on a Lenovo G570 with an Intel Core i5-2430M and 2x4GB memory.
Recently my system has only been displaying 4GB memory on Task Manager and System, so I went to Direct X diagnostic tool and found out that my Intel HD 3000 is using 3GB as shared memory. Why I said recently is because a while back my OS was correctly displaying the full 8GB RAM while the shared memory was only taking 1GB. Is this normal or not?
I know shared memory for Intel HD is determined automatically, but I've never seen it using more than 2gigs.
My BIOS is displaying the full RAM value, 8GB, while in Windows, both on TaskMgr and System Properties, it says 4GB.
Here are two screenshots from DirectX Diagnostic Tool.
I don't think this is BIOS issue and what I'm asking is: Is this issue normal or not? I need to know if this issue is the one that causing my OS memory reads problem.
