I recently put together a budget system using an ASRock B350 Pro4 and a Ryzen 5 2400G but I cannot find the option to change the shared memory size in the BIOS. The manual shows it under Advanced North Bridge Configuration but I don't see it on the BIOS screen. Anyone know where it is?

Exactly what I want to know. I have checked every option for it and found absolutely nothing so far.

If I remember correct, you should go to Advanced => AMD CBS => NBIO common options => GFX something and there you can change shared memory.

found it after no less than 4 hrs of random searching.

Advanced\AMD CBS\NBIO Common Options\GFX Configuration

Set Integrated Graphics Controller to Forces

Then I set UMA Mode to UMA_SPECIFIED
And the Option UMA Frame Buffer Size showed and set to 4G for my 16Gb Ram pool.

I asked on Reddit and managed to find it, but have another problem. When I set it to 4 GB or higher it's only allocating 2. Any ideas why?

thinking it is a limitation for now. Mine shows 2Gb as well. Another bios revision or two and maybe we will see that 4Gb.
