Generally, yes. Modifying these values doesn't physically damage your hardware. However, there are some trade-offs to consider: I need help with my VRAM - HP Support Community - 7236143
Changes the reported VRAM value (e.g., from 32MB to 1GB) so games bypass initial compatibility checks.

Some community discussions describe the tool as “creating a virtual video RAM space” **** . However, the dominant understanding is that it is a registry‑based spoof, not a true memory‑doubling engine.
Because the original PHDGD website and tool distribution channels have largely gone offline, you do not need to hunt down risky, unverified third-party executable mirrors. The exact behavior of the tool can be safely and manually replicated directly inside the built-in Windows Registry Editor. Step-by-Step GMM Registry Modification
The tool works by performing that trick the operating system and games into reporting a higher amount of dedicated VRAM than the hardware actually possesses. Find the "VRAM" or "Virtual VRAM" section within the tool

Deployment & integration
Dedicated Video RAM (VRAM) is the lifeblood of modern PC gaming and graphic-intensive applications. When your system lacks enough physical VRAM, games stutter, frame rates drop, or titles refuse to launch entirely. For gamers running integrated graphics—such as Intel HD, UHD, or Iris Xe graphics—VRAM limitations are a constant hurdle.
Right-click the parent folder, select , and name it GMM .
The acronym stands for Poor Man's HD Graphics Driver . Originally started by a developer known as IntelliModder32, the PHDGD project focused on creating modified, tweaked versions of official Intel graphics drivers. The primary goal was to squeeze extra performance out of low-end Intel integrated graphics chips, allowing them to run games they were not officially supported to play. However, there are some trade-offs to consider: I
This is the most critical point. The tool does not “create” video memory. It only changes a number that software reads. The actual physical memory available to the iGPU remains unchanged **** . Consequently, once a game is running, if it truly requires more memory than available, it will still stutter, crash, or fail to load textures properly **** .
