Can't find a way to change the vram for R7 4700u.

I bought a Vivobook s14 with a R7 4700u and the default vram is 512mb... I searched every little settings menu and I tried some third party apps but I still cant change it. I tried in the BIOS and it won't let you change it. It's very irritating because usually the GPU spikes to 99% usage and the CPU is chilling at around 30-40%. Am I going to be stuck with 512mb of vram or is there a way to change it? Can I use some other version of the BIOS or something?

It is built this way at the hardware level, no way you can change it whatsoever. The onboard GPU should be able to use part of your RAM (shared GPU memory in task manager), but you can't manually change that either beyond replacing the SODIMM sticks inside. 

Fuck you scalpers, fuck you scammers, fuck all of you jerks that charge way too much to tech-illiterate people.

Also the 99% GPU usage usually means it is using all of the computing resources, not the whole frame buffer (aka VRAM). For example on PC furmark will run a 1050ti with 4GB of VRAM at 100% usage, but it isn't even using 1GB of VRAM.

Sorry for the late reply, but no. If you change out the sticks you don't unlock customization. There is a chance that doubling RAM capacity will increase the amount of allocated shared GPU memory, but chances are it won't, and you will only see the benefits of extra RAM, if your uses would benefit from an increase in RAM. 

I don't remember where I saw it, but there are hard limits in place (IDK if it is in the OS, GPU, or maybe mobo? I don't remember) on how much RAM can be allocated as shared GPU memory. And you are probably at that limit already at 512MB.
