I need a MINI ITX motherboard with Unified Memory Architecture

[raghavsood999]

Hello friends...

I have the following APU: AMD Ryzen 5 3400G with Vega 11 GPU and it has 2GB VRAM accessible.
I need Vega 11 to address up to 8GB of VRAM and i know some motherboards such as the Gigabyte A320M-S2H motherboard have a feature in BIOS called the UMA which allows shared system memory to be allocated as VRAM to Vega GPU's up to 16GB. So i was wondering if there is a MINI ITX or PICO ITX board in this form factor. I need nothing larger than the MINI ITX form factor. The 32GB or 64GB or above RAM support can be supported and the board MUST have at least 2 RAM sockets available and can support either DDR3 and DDR4 support.

The Vega 11 GPU on my ASUS board currently on does 3GB MAX but someone told me on this forum under the graphics cards section that there is a Gigabyte A320M-S2H motherboard with UMA technology and can i can address optionally 3,4,6,8,10,12,14,16GB of vram to Vega iGPU. So where are these boards with mini ITX form factor

ill try and restate what was said in the other thread about vega 11 and memory access.

if you set the memory in the bios for the igpu to 4gbs in a system that has 16gbs in it, windows will only be able to access 12gbs of ram. the igpu on the other hand can access 4gbs and more. so if you load something like skyrim up with a crap ton of hd res mods than the igpu will need more than 4gbs and pull it from the system memory. what you are doing by increasing the igpu memory limit in the bios is reserving memory for the igpu to use and telling windows that it can only use 12gbs for apps and everything else. the igpu still can use more. so, if you set it to 64mb its still not going to limit the igpu performance unless the system is low on memory in the first place.

Thanks for your reply I understand now but I have a HP Pavilion dv6 6145tx laptop with ATI RADEON 6707m Video Card with 1GB VRAM and it has no UMA feature in Bios and has latest BIOS. So UMA is specific to only some motherboards like GigaByte or the one mention in the video of thumbnail. Can you justify why the BIOS has option for UMA then because you stated that even if Vega 11 has 65MB VRAM locked, it will still be able to get 4gb more of a game needs it. Then why is there a higher limit option in the Bios for UMA?
