Hi,
If you have 3D enabled for the display in the virtual machine settings, then it uses more RAM.
The shared graphics memory that you can configure under the 3D configuration for the video adapter all comes from your host RAM, not the graphics adapter.
This is most likely the reason that you are seeing this.
If you disable the 3D feature then the RAM usage is much more in line with the actual RAM settings for the guest OS.
Hope this helps,
