I think it defaulted to 32MB and can even be as low as 16MB, but you want to leave a little bit for system start-up. The amount reported can be modified or disabled if desired by changing the following registry value:. When no graphics-intensive operations are occuring, most of the DVMT memory can be reallocated to the operating system for other uses. I do not know about actual support, but if the question is whether memory is allocated to the graphics, then at least on my laptop with Intel i3 processor and HD graphics that does happen.

This ensures that the graphics processor has a guaranteed amount of graphics memory. I wouldn’t suggest that its entirely safe, as phawx said, its entirely possible that if the timing isn’t supported by the ram, you wont have an opportunity to fix it if the system doesnt boot.
No one has confirmed the bios reset keystrokes work under these conditions. This figure from Intel clearly shows the differences between the three different DVMT operating modes:. Come visit the community Discord channel or the subreddit general chat!
