In addition to DVMT, 852/855 chipset also supports the selection of four different sizes of pre-allocated memory: 1 MB, 8 MB, 16 MB or 32 MB. This amount is chosen via the system BIOS setup as a setup option. This pre-allocated memory selection is supplied for legacy VGA and SVGA Graphics support and compatibility.
When FIXED Memory Size is set to 0MB and this BIOS feature set to 32MB, up to 32MB of system memory is allocated as graphics memory in the
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 Dedicated Video Memory = 64MB, then DVMT pre-allocated memory in BIOS settings is 96MB.
Quali sono i vantaggi di DVMT? DVMT assicura l'uso più efficiente delle risorse di memoria di sistema disponibili per le massime prestazioni grafiche 2D e 3D. DVMT allinea con le linee guida di progettazione per i driver Microsoft.

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.
Notice that the BIOS setting right under the one in question is called DVMT Total Gfx Mem. 2015-12-10 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.
The main idea of DVMT is to increase the efficiency of memory allocated to a system or GPU. However, before delving into the details of individual modes, it should be noted that the system boots with a pre-allocated system memory for graphics, regardless of the DVMT operating mode.

When an application no longer needs extra memory.
Generally, it is recommended that you let the graphics driver allocate memory in DVMT mode. This allows the driver to dynamically allocate memory according to changing situations. From the screen shot on my set up, the DVMT pre-allocated variable for 96MB (which results in 64MB in Windows) is 0x18C 0x3, so I would type in the dos prompt Code: setup_var 0x18C 0x3
I've read a warning in a DELL Guide (here) about editing the DVMT Pre-allocation using the EFI Shell Warning for 4k / UHD screen owners: Do not use the EFI shell to to edit the DVMT Pre-allocation for getting your screen to work. This bricked a user's machine already.
