Increasing VRAM

[lorenzopanero]

Hi everyone, before I begin I just want to say thay I'm nothing like an expert in this subject so I'll be more than glad to receive any kind of answer.  My problem is that i own a laptot which has 16GB RAM, but only 128MB are dedicated to the video card. I know for sure that normally there's a way for increase VRAM, so I did a little resarch. I tried with firmware settings UEFI/BIOS, but I didn't find any available option. Then I discovered that my PC, which has an INTEL i5-1235u as video card, could support Intel Arc software. After downloading it, I found an option called Resiziable Bar, which was not available. I realised that that was what I was looking for all along. I did another bit of research and I discovered that I have to enable Resizable Bar from my BIOS. In other BIOS there's for sure an option but not in mine. I tried to update my BIOS but it was already up to the latest version. Can you help me? If you need any more info about my specifics i'll be glad to provide

Integrated video (iGPU) does not have room for keeping 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: Last year people posted Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable.

Ok thank you for your quick response. I found the youtube videos you mentioned, I didn't do anything I wasn't 100% sure about, but what do you mean by "unpredictable"? What could possibly happen using regedit?

Machine won't run at all. You can try if you wish.
