: Restart your PC, enter your BIOS setup, look for "Advanced Chipset Setup" or "Graphics Configuration," and manually increase the DVMT Pre-Allocated Memory to 512M or 1024M.

It cannot magically turn your system RAM into ultra-fast GDDR6 memory.

Deployment & integration

To understand what happens under the hood when using the PHDGD tool, it helps to look at how Windows classifies graphics memory:

Right-click the folder, select New , and click Key . Name this new key GMM . phdgd virtual vram tool

Right-click the parent folder, select , and name it GMM .

PCIe 4.0 x16 provides ~32 GB/s, compared to a GPU’s internal VRAM bandwidth of ~1000 GB/s (e.g., RTX 4090). Thus, even optimal paging cannot match native speed.

Integrated Graphics Processing Units (iGPUs) do not have their own physical, high-speed VRAM pools like dedicated Nvidia or AMD graphics cards. Instead, they dynamically borrow memory from your system's RAM (Dynamic Video Memory Technology, or DVMT).

Configuration parameters likely include: : Restart your PC, enter your BIOS setup,

: Some games perform a hardware check before launching. If they detect only 128MB of dedicated VRAM, they may refuse to run.

Double-click it, change the Base to , and type your target value (e.g., 1024 for 1GB or 2048 for 2GB). Click OK . Step 3: Reboot and Verify Restart your computer. Right-click your desktop and select Display settings .

Click on the new GMM folder. Right-click in the right pane, select , and name it DedicatedSegmentSize .

Integrated graphics cards do not have their own memory; they share the system RAM (Dynamic Video Memory Technology - DVMT). However, Windows reports a small portion of this as "Dedicated" memory. Many games blindly check this small "Dedicated" number and refuse to launch if it is too low, even if you have 16GB of System RAM available. Name this new key GMM

It inputs a hexadecimal value corresponding to your desired virtual VRAM size (e.g., 512 for 512MB, 1024 for 1GB, or 2048 for 2GB).

When you run the tool and select a profile (e.g., modifying the value to 1024 MB, 2048 MB, or 4096 MB), the tool writes configuration data to the Windows Registry—specifically targeting keys associated with display adapter properties (like the DedicatedSegmentSize registry hack). When a game queries the operating system to check your hardware capabilities, the OS returns the spoofed value configured by the tool. The game is tricked into launching, bypassing artificial hardware blocks. Benefits of Using the Tool

Many video games check for a minimum amount of "Dedicated Video RAM" (VRAM) before starting. While modern integrated graphics dynamically allocate system memory as needed, older games and software often look for a static value (like 128MB or 512MB) reported by the hardware. If the iGPU reports "0MB" of dedicated VRAM, the game may crash or refuse to open, even if the system has 8GB of total RAM available to share. How the PHDGD Tool Works
