Hi so here is where I think the misunderstanding is coming in, you are expecting the VRAM to increase, but that 512MB is only for basic thing on the APU, like displaying frames to the monitor: For example, something like the 4800H I think is the gaming counterpart for the 4700U. It might be that they are limiting the capabilities of the 'u' chips, I think the 'H' chips are more relevant for gaming.
It is possible that Windows dynamically allocates more RAM as "VRAM" while playing, but you'll only be able to see it with Overlays.Įdit: Furthermore, the 4700u is an energy efficient chip. The XBOX One and PS4 also shares main memory between the system and APU (and that was even still only DDR3). I have read that some laptops do not allow you to change the VRAM in the BIOS, but this is not necessarily a bad thing, since it is only a default value.
If you are not familiar with MSI Afterburner, you can try using the Radeon Overlay while gaming, you do this by pressing Ctrl+Shift+O while in the game (it will not work in OpenGL games). It won't necessarily change the value you see in Windows, since that is a default value. Since this is how operating systems are programmed, they do not use all available RAM at all times.Ī better way to test it, would be to launch an application (such as a game) that requires at minimum 1024MB of VRAM and to use an overlay such as MSI Afterburner to determine how much VRAM (Graphics Memory) is being allocated during the gaming session. Hi might be a pity, but it is not too say it is not true.
