Resolved Question

Dedicated Video

Jul 19, 2017 8:54AM PDT

I have seen several tutorials on how to increase the dedicated video card and it seems that as of now the only way to do this is to follow the path : HKEY_LOCAL_MACHINE\Software\Intel\GMM, create a REG_DWORD value named “DedicatedSegmentSize”, I've noticed that many are able to do this but the people with 8GB are unable to change the dedicated video, is there a reason for this or could someone care to share a solution for this please.
I would greatly appreciate it.
Thank You

Clarification Request
specifications
Jul 19, 2017 3:33PM PDT

Sorry for the lack of details, I was in a bit of a rush when I was posting this.
The specifications are:
Lenovo all in one, Windows 10, Intel(R) Core(MT) i3-3220 CPU @3.30GHz, RAM 8.00, X64bits, HD Graphics 2500, Available Graphics Memory: 1792MB, Dedicated Video Memory: 32MB.
The game I'm looking at asks for 256MB of Dedicated Video Ram, all for the other requirements are met, I saw that the Dedicated Video Memory Could be increased by going through: HKEY_LOCAL_MACHINE\Software\Intel\GMM, create a REG_DWORD value named “DedicatedSegmentSize”, I did, made the modifications but the Dedicated Video Memory remained at 32MB, I saw many post of others that had 2 or 4 of Ram and it worked for them, but the ones with 8RAM, had the same problem I encountered when trying to change to 1024MB.

This rarely works and folk often ask why.

The reason why changes with the hardware. Let's hear more about your laptop and maybe I can find a document that shows the max dedicated RAM for video. If the hardware doesn't support it, this is why it doesn't work.

Be aware this does NOT improve video performance for gaming. Some go through all this and then complain it didn't help.

You can look around your BIOS and settings.

https://communities.intel.com/thread/55054 is a common back and forth but this sort of graphics system is not changeable on most systems.

Hopefully you have the Maximum DVMT option and that's as good as it gets since the other memory is hardwired in the CPU.
