Hi, I just noticed that the AUTO option for dedicated VRAM (GPU Memory) is missing in the latest BIOS version (01.03.00) and now only specific numbers (512mb/2GB/4GB/16GB/32GB/48GB) can be chosen but not the AUTO option which was quiet nice as it allocated more RAM for CPU usage if needed or more for GPU usage when needed. Now I have to always restart the device when I want to change the allocation (for example to use a GPU intensive task). Did someone found a fix or do we have to wait for the next BIOS version.
FYI I got the 64GB memory version so maybe that's only an issue for my configuration but I would believe all other versions (32GB/128GB) are affected as well.

Hi. It seems like that setting is the min amount, not max. Can you please try choosing 512m and running something heavy to test if this is so?

The amazing thing about AMD’s technology is that should the GPU run out of its ringfenced memory, then it can seamlessly borrow more from system memory, if available, temporarily expanding its capacity. Since this memory resides in the same physical location, access remains very fast. Even with the smallest 512 MB profile, when borrowing 10 GB, we found 3D performance only dropped by a few frames per second, maintaining that all-important smooth experience within the viewport.
