How to increase my dedicated vram?

[redandwhite]

hello.. 
i have hp envy x360 15 with a ryzen 4500u + vega 6 iGPU and 8gb of ram..my dedicated vram is set to only 512 mb and i looked into bios and couldn't find a way to increase it.. like some of lenovo ryzen 4000 series based laptops.
so my question here why HP? and if i upgrade the ram to 16 gb do i ll get 1024 mb dedicated vram? or its exclusive to vega 7 iGPU that come with the ryzen 7 4700u?

Integrated video (iGPU) does not have room for keep VRAM, it relies on System. System will work this out and allocate/assign spare/available system RAM to VRAM automatically when required up to max limit. System will also take VRAM back when required (the number is dynamic, not fix). During the good old days, we could do this from BIOS but now OS is smarter.

The following document shows Max shared RAM for Intel iGPU versions (I can't find a similar list from AMD).

Note: Recently people post Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable.

from what i know with 8 gb ram on my system i only get up to 512mb vram.. im just wondering if upgrading my ram to 16gb will get me the extra 512mb on my vram ?
i know the ryzen 7 4700u with a vega 7 iGPU has up to 1024mb vram .

should i upgrade my ram or the vega 6 iGPU is locked to get up to 512 only?

Hi, @redandwhite 

I have an HP Envy x360 15-ee047nr with the same Ryzen 4500U processor, onboard AMD Vega graphics, and 2 x 8 GB of DDR4-3200 memory, and the dedicated video memory is 512 MB.

You may get more shared system memory allocated for the video adapter by adding another 8 GB memory chip, but the dedicated video memory will always be fixed at 512 MB--even if you max out the memory to 2 x 16 GB.
