Question B450m ds3h and Ryzen 5 3400G

[KowalPLK]

I have a question. I have Gigabyte B450M DS3H and Ryzen 5 3400G and 8GB RAM. I can't find option in UEFI to set quantity of shared ram to graphics card GPU. UEFI set 2 GB for Vega Graphics card and Windows 10 show that system have 5,95 GB installed memory. I want to set 512 MB or 1 GB for Vega Graphics card GPU.

Enter the BIOS and go to "Chipset",
Set Integrated Graphics to "Forces",
Set UMA Mode to "UMA Specified",
Set UMA Frame Buffer Size to "512 M" or 1G.

In my mobo there isn't that options.

Yes they are, check the video, and put bios to Normal mode.

You need to set the first option for the 2nd and 3rd options to appear.

Well there's a bit of confusion here. The first time i encountered this i was confused too.

You can have up to 2 gigs uma iirc. Uma is different then what the op was asking for. Finding this setting can be frustrating as i had to do the same thing on my b450m and 2400g


The graphics card will pull memory as its needed. The amount it will pull is determined based on how much memory you have installed. With 16 gigs memory you can pull up to 8. With 32 gigs you can pull up to 16 gigs for the graphics card. Its automatic. The uma just endures a certain amount of memory is always available to the apu but it isn't a hard limit

For most games smaller low res textures work toward your advantage in terms of speed because there is less to shuffle across memory which tends to be slow.

If you're doing large dataset work or video work then the system will pull what is necessary based on your schedule installed ram.

Sorry to reply so late but I had no way. In my UEFI.

There is no such option in my UEFI. I take a photo.
