Why does changing my vRam in Register-Editor not work on my Intel HD graphics 4000?

[NIJpm]

I have an HP elitebook 2570p with 8 GB Ram and an Intel HD 4000 graphics card. My vRam is dedicated, so it shares ram with my normal ram. It says I can possibly have 1.7GB. I tried changing my vRam in the BIOS, which did not contain such an option. So I found this video: https://www.youtube.com/watch?v=szn5Mgb-IQs How to increase dedicated vRam on intel HD Graphics (without BIOS) [still working in 2017] - YouTube

It contained a way to change your vRam in the Register-Editor. It worked for a lot of people, but not for me. I used a QWORD(64-bit) and 1024, because of my 8 GB ram. I restarted my Laptop, but nothing happened. Can this solution work and if not, what can work?

@Stefan3D I had a look at that page, but I have windows 10 and the downloads from that page did not support that. I searched for a driver update from HP as a generic update from intel did not work. I updated it. But still, it did not work. I tried using dword, qword, GMM, DVM, 1024 and 512, but nothing seems to work. Do you know where the problem lies?

Why do you want to change these settings at all? If you are running Windows, the graphics driver will manage - and optimize - the memory usage necessary.

I am not able to go higher than around 500-600 MB. I wish to get at least 1Gb so I can play most games on low settings. I cannot even play fortnite Royale on custom lowest settings. Anyone got any idea how to higher the amount of given vRam? I can do about 1.7Gb

Intel hasn't updated the WDDM of the Intel HD 4000 driver, so that feature is not available on this card. They probably won't update it, just buy a new system or dGPU.
