Ryzen 7 5700g - How to adjust the UMA Frame Buffer from 512MB to 2048MB?

Good morning friends,

 

I have an Asrock B450M PRO4 F motherboard

AMD Ryzen 7 Processor 5700g

 

And it doesn't show up in the device manager that it's a Vega 8, it just says AMD Radeon Graphics,

 

And, in the AMD Radeon App, it says I have 512MB of VRAM while 2GB is shared in the BIOS,

Device Manager and others, from my computer:

AMD Radeon application indicating 512MB:

My TechPowerUp GPU indicating 512MB:

Meu Ryzen 7 5700G Não aparece Vega 8 e Só tem 512 na VRAM.PNG

Where I set it up in Bios for 2GB VRAM:

Image found on the internet of how it should present the Ryzen 7 5700G:

Where it clearly shows that it should show the amount of megs allocated in the BIOS,

This one from someone else, appears 4GB in the VRAM,

Now an image proving that my VRAM is 512MB, not 2GB,

 

Because I installed an application that displays the VRAM on screen while playing Fortnite:

 

Top left side of the screen appears 489MB VRAM

Thanks friend, I couldn't have gotten here without your help, I researched about other motherboards on how to configure, alternative ways and found that there is another configuration to do, forcing the VRM in 2G, even if a 2G VRM is already forced, maybe a motherboard problem, but there was a second option in the BIOS,

No need to update, I'm still on version P2.40, the latest being P2.80.

1. I have reset the BIOS setup under Exit > Load Uefi BIOS Defaults

2. Advanced > Onboard Device Configuration > UMA Buffer Frame Size: 2GB

3. Advanced > AMD CBS > NBIOS Common Options > GFX Configuration > iGPU Configuration > UMA Specified

4. Advanced > AMD CBS > NBIOS Common Options > GFX Configuration > UMA Frame Buffer Size: 2G

5. F10 (Save and reboot)

ALL OK!

Now I have to see the issue of my memory that doesn't seem to be pushing 2933 mhz,
But that's another problem,

Thank you all

The VRAM is working
