You are not facing any problems. On your nuc, with Intel graphics, memory will be allocated up to 50 percent of the memory available, as needed.
Al is right, pending that your Operating System is Windows 10. Please read this: https://www.intel.com/content/www/us/en/support/articles/000020962/graphics-drivers.html
