How to increase VRam for Intel integrated GPUs

[armirol]

Hi, i saw that question many times with no answers. As i found a solution, i decided to post it.

This is working at least for Intel integrated chip 520, 620 and 630 as i did it on those. It should work for almost all of them at least up to 630 and at least on all version of Windows 10 until the latest update as of 06/19/2018. i think it might work on earlier Windows versions (7, 8. 8.1...)

Run regedit
Look for HKEY_LOCAL_MACHINE > SOFTWARE > INTEL
Right click on INTEL and select New > Key
Rename the new key to GMM
In the left windows, right click and select New > DWORD (32 bits)
Rename it (respect case!) DedicatedSegmentSize
Double left click on that new name
Enter the amount of VRam you want to use, click ok (i used 512 Hexa and it worked for many softwares running on multiple 4k screens)
Restart the computer

Enjoy!

This would change what the system reports the memory is, not actually what it is using. It can help with games not installing or running, not will not change performance of the card. It's like painting a door on a house, everyone will think there is a door there, until you try to use it.

You need to go into your BIOS/UEFI and tell your iGPU to use what RAM you want. I have mine set to use 4gb RAM, the max it will allow.
