This is some OEM Board it seems, they often lacking from some important Bios options. In this case you cannot change the dedicated memory size, unfortunately.
increasing memory from bios wont help anyway. in idle state it shows 64 mb but as u run games etc it goes higher depending on how much ram memory u have got. u can check it in cpuz.
It helps for games with wrong memory detection such as GTA4, Max Payne 3 or Trackmania. And you are wrong, if you set the dedicated RAM to 512 MB, it is available in every state. The load state doesn't make a difference.
As you can see your dedicated memory size is 64MB, that's it. It won't go higher automatically. The application can use a lot more RAM of course from the shared system memory, but some games detect it wrong. If you start a game like GTA4 you will notice that.
here u can see...i ve checked this in almost all games including rockstar games la noir where it touches 700 mb+ havent played gta4.... but i know intel card have some issues with rockstar games .... people who overclocked ther hd 3000 from 850 default to 1800 can get it to run smoothly. even l a noir runs at 15 fps.
That's not your dedicated memory size, it stayed the same as you can see in your screen. As I said the iGPU can theoretically use all of the dynamic RAM which is 1,7 GB big or 1,8 GB. Some applications like GTA4 detects only your 64 MB and refuse to run or don't let you run in a higher graphics setting. That's the problem. Basically the dedicated memory size is unimportant except for some applications with a wrong VRAM detection.
