The amount of allocated RAM which you are changing (and running out of) is on the video card. It's completely independent from the motherboard RAM. You cannot allocate more to the video card. You would need an adequate video card that has enough VRAM on it. If you are using an onboard video card such as an Intel HD 3x, 4x then its no suprise there isn't enough RAM for it. If you have an integrated video card, then I have bad news for you. The current max amount of RAM which can be allocated is your cap, unless you can upgrade your graphics card. If you are playing on a desktop and your graphics card is not integrated then the solution to your problem is as "simple" and probably costly as upgrading your graphics card.
