Intel UHD 630 with 3mb vram

[carlosadsf]

Hi guys, i need some help with my integrated graphics.

I follow OpenCore Dortania Guide to install the Catalina 10.15.7, and when i enter on system i dont have
graphics acceleration, the system show me Graphics Intel UHD Graphics 630 with 3 MB.

Im using a hdmi cable pugled into b360m hdmi port.

I tried allot configurations in device properties using:

"PciRoot (0x0) / Pci (0x2,0x0)
AAPL, ig-platform-id
framebuffer-patch-enable
framebuffer-stolenmem"

All them show me 3mb or errors like black screen, green screen, slow loading and freezing in loading.

Now Im using:

"PciRoot (0x0) / Pci (0x2,0x0)
AAPL, ig-platform-id = 3E9B0007
device-id = 923E0000
framebuffer-patch-enable = 0100000
framebuffer-stolenmem" = 0003001

This configuration load Catalina very fast but with the same, without graphics acceleration.

My setup:
Intel i5 9400 2.9
Gigabyte B360M Aorus Gaming 3 - F15b - OpenCore 0.6.9
Intel Graphics UHD 630
16GB Corsair 2x2
SSD m2 NVMe Netac

Bios configuration:
Internal Graphics - ENABLE
DVMT Pre-Allocated - 64M
DVMT Total Gfx Mem - MAX
Initial Display Output - IGFX

I dont have EGpu but for the future i will buy one.

I do no how to fix this.
Can you help me guys?

Sorry for my bad English.
