MSI PRO B650-S Wifi Board

[rohit.nanda.second]

Hi,

I have a Ryzen 8700G on an MSI Pro B650-S Wifi board. How can one increase the UMA vram to 32GB. The maximum it shows on the UEFI BIOS screen is 16G.

Why 32GB UMA: Then one can use ROCm and gets a 32GB graphics card for running inferencing servers (LLMs)

Another question: Can this dedicated UMA vram be increased further if the system has more memory?

Hello. Do you know how use flash bios button? bios file editing is not an issue. If you know how to install it, a mod might work.

Thnaks Maxinator, Could you guide me to the correct type of BIOS MSI uses in the new AM5 motherboards and how to do it. Can these BIOS variables be changed by using some utilities which booths the UEFI mode?

The correct type? I'm sure they all are UEFI ones nowadays.
Variables are changeable. BUT, uma frame buffer size setting is outside of Setup module scope. This setting sits in CBS module, and any change to the corresponding variable might have no effect, since it will not be processed. You may try scewin and see if it works.
