    Dedicated memory not used


      I'd like to know how to direct my computer to use more of my graphics card memory instead of the RAM. Or, I'd like to understand why more graphics card memory is not used.  I have 4 users on 4 terminals.  One uses firefox and excel, the other three all use Firefox and Autodesk Inventor or AutoCAD.  MSI afterburner shows the AMD graphics card as only using about 10 or 11 MB constantly.  The on-board Intel shows as using 22 MB constantly.  The UEFI/BIOS has the AMD graphics as primary and iGPU memory set at 1GB.  I'm afraid that my RAM is being used (shared) for graphics but the dedicated memory is not being used.  I'd like to post info from the CCC but it seems not to have loaded.  CCC is not working so I used DXDIAG.

          I think you have incorrect information.

          Use GPU-Z (second tab) and HWinfo64>sensors only to detect your VRAM usage for both GPUs.You can force GPU-Z to display max values instead of current.

          As i can understand, applications will use VRAM of that GPU which video output is used for displaying image of that application.

          Therefore heavy 2D/3D applications must be moved to monitors connected to HD 6670. Sorry if i am wrong.

              2 users are using Firefox and are using about 6 GB out of the 8 GB of RAM and about 100 MB of the graphics RAM.  Firefox is crashing.

              2 of the Inventor/AutoDesk user's monitors are connected to the HD6670 card.  I can use Windows Task Manager to see how much memory (private working set) each process (application) is using.  I don't see a way to tell how much graphics memory (as opposed to computing memory) a process is using.  I went into the UEFI last night and saw that I can set the internal graphics chip dedicated memory usage to 1 GB (I think I'll scale this way back like to 128 MB) and that way free up some more computing memory.  I don't see a way to tell the computer to use the dedicated graphics memory and not use shared memory either for the on-board intel chip or the HD6670.

                   It appears that there are no heavy graphics memory applications.  No one is playing a video game.  Maybe the graphics memory is just not used.
