Shared video memory?

So I have a 2070 super 8gb. 
 

does the shared memory mean that if needed more than  the 8gb that up to 8gb of my system memory can be used for graphics

Shared memory is the amount the the graphics card can use if the primary frame buffer aka vram is full. At that point however you will suffer a significant drop in overall performance (see GTX 970). 

Theoretically your GPU could access slow DRAM if needed but with modern games, still very unlikely.

Yeah so basically it can use up to 8gb of my regular ram if it maxes out my 8gb vram. Cause I was honestly thinking about that before I seen this on my computer.
