Once you find the section of the BIOS menu that contains the “Graphics Settings” or “Video Settings” option, changing the amount of memory allocated to the onboard video card is relatively simple.
There is no way for you to adjust the Shared Memory on your computer. I have examined the BIOS for your system and the option to adjust the Video Memory is not there. On the bright side just because you see 4 gigs for the Shared Memory does not mean it is using 4 gigs.
How do I reduce video memory size?
How to Reduce Video File Size without Losing Quality
- VLC (Windows, Mac, Linux) As one of the most popular media-viewing and -editing apps around, it’s no surprise that VLC is a great choice for making video files smaller.
- Shotcut (Windows, Mac, Linux)
- QuickTime Player (Mac)
- VEED (Web)
- VideoSmaller (Web)
- Clipchamp (Web)
On discrete GPUs this is your VRAM. (Note that most integrated GPUs typically use shared memory because it is more efficient). Shared memory represents system memory that can be used by the GPU. Shared memory can be used by the CPU when needed or as “video memory” for the GPU when needed.
It just means that there are some jobs that need the CPU to do some work as well as the GPU. If shared memory was up at 6GB as well as or instead of the dedicated GPU then you might have cause to be concerned, but at such a tiny amount it is not doing any significant amount of work in that area.
Is shared GPU memory slow?
Shared memory does indeed have a heavy performance hit compared to the actual GPU memory, but you are using only 0.2GB with 5.8GB in use on your GPU. That is approximately 3.5\% of the total memory use.
