Shared intel UHD graphic memory

[GurbanovR]

I use blender app. While rendering animation according to task manager, GPU works 100% but actual shared memory just getting used below avreage. Is there any method to utilize all GPU memory for rendering (I have intel UHD Graphics 620)?

The following document shows the max number Intel UHD Graphics 620 can get

If it could not get to the max number, please add more RAM (if available) to your machine.

You responded what's calculation not answered my question.

Everthing is alright with system calculated shared or dedicated GPU memory altoghether. Let's get example: 

I have 128 mb dedicated memory

I have total UHD graphics 620, 5.9 gb memory

While rendering animation used staff:

I have 12 RAM, used around 6gb, that's fine

Laptop uses just only 1.4 or sometimes 1.6 gb shared GPU memory out of 5.9gb but task manager shows 100% memory utilization which does not seem normal. Of course, laptop freezes, performance goes down and gives lot's of lags. 

I ask you is there any way to simply force all shared GPU memory utilize for current process or 5.9 gb is just junk screen number?
