Oct 26, 2017 For Intel integrated graphics processing units (GPUs), this represents 128 MB DVMT pre-allocation set in BIOS. Consult other vendors for how
Feb 13, 2019 Select the Chipset section; Change DVMT Pre-Allocated to 1024M; Change DVMT Total gfx mem to MAX; Go to Save and Exit and select exit
Find the variables for the DVMT Pre-Allocated memory and the related values. In this case, DVMT pre-allocated memory's variable is 0x1C3. The value of 96MB is 0x3. Record these two values. Preparing Bootable USB with UEFIShell Use a USB Flash Drive Format it as FAT32, MBR Extract the EFIShell you downloaded above. You'll find a folder named BOOT. The amount of video memory is dependent upon the amount of pre-allocated memory set for your system plus something called DVMT.
It's locked for video use only and invisible to the operating system. Older Intel graphics products allow you to set pre-allocated memory in the system BIOS to 1 MB, 8 MB, or 16 MB. In the bios settings there is an option to set DVMT to 128MB, 256MB, or MAX DVMT. (1696MB, information given by Intel graphics panel). Looking at the information panel of Intel graphics, we can see the size of allocated memory to DVMT, going higher following windows openings.
This works for many laptop and desktop computers.
The advantage of this method is it can be applied to all the manufacturers, without flashing and unlocking the BIOS. The amount of video memory is dependent upon the amount of pre-allocated memory set for your system plus something called DVMT. DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance.

DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance. The DVMT in DVMT Pre-Allocated stands for Dynamic Video Memory Technology and is an incredible feature that Intel has built into the hardware the GPD Win uses. Notice that the BIOS setting right under the one in question is called DVMT Total Gfx Mem. I didn't understand exactly how DVMT works, so I don't know if I need to increase the DVMT pre-allocated or not. When I buyed my pc, the data-sheet said that the vram of my computer was "up to 1GB", but when I checked the amount of dedicated video memory, the Windows showed "32MB". In the bios settings there is an option to set DVMT to 128MB, 256MB, or MAX DVMT.
- DVMT-prealloc set to 96MB or 128MB in BIOS - Haswell: ig-platform-id 0xa2e0008 - Haswell: framebuffer configuration for 0xa2e0008 patched to match DVMT-prealloc value (Broadwell determines BIOS size dynamically) - "normal" requirements for Haswell/Broadwell systems
The high 8 bits store the DVMT pre-allocated memory value set in BIOS. For example, 0x01, 0x02, , 0x10 represents 32MB, 64MB, , 512MB, while 0xF0, 0xF1, 0xFE represents 4MB, 8MB, , 60MB. You could find all possible DVMT values from Section 4.1.28 in Intel's manual at here . If Dedicated Video Memory = 0MB, then DVMT pre-allocated memory in BIOS settings is 32MB. If Dedicated Video Memory = 32MB, then DVMT pre-allocated memory in BIOS settings is 64MB.

If DVMT pre-allocated memory in BIOS settings is larger or equal to 128MB, the StolenMemory that could be detected by OS is (DVMT) MB. (equal to the value of DVMT pre-allocated memory) Now let’s come back to our topic, Dedicated Video Memory >=64MB (i.e. DVMT pre-allocated memory >= 96MB) will pass the assertion/kernel panic. I canot change the DVMT Pre-Allocated to 1024m every time i do, my monitor quits working and i have to clear cmos just to get back into the bios.

Depending on the system BIOS implementation, the amount may or may not be configurable. Dynamically allocates and de-allocates the optimum amount of memory for balanced 2D, 3D graphics, and system performance.
