Simply put, you can't. Intel does not support your processor on Windows 10. and does not ship a graphics driver for it for Windows 10. You are currently running using Microsoft's compatibility driver. This driver cannot be configured to use any additional memory.
At this point in time, I am sorry to say that your only option is to replace your system with something a *lot* newer. You could use an add-in graphics card, but it is very difficult to find compatible graphics cards these days (hint: I have found NVIDIA cards to be much more compatible than AMD/ATI cards)
