RAM config that isn't a power of 2?

Framework Desktop
1

Does anyone know if there is a way to configure RAM on the Framework Desktop to not be split between 2 powers of 2? Like 48 GB system memory, 80 GB VRAM in case of a 128GB model? I don’t see an option like this in the BIOS, maybe in Linux or AMD driver configuration?

AMD only sells the Strix Halo platform in binary amounts of memory. If you use windows you can specify how much memory the gpu gets, because it is too dumb to dynamically allocate like *nix systems do

I think they are asking not about the purchase configuration but about the config of memory under Linux
Jeff Geerling has posted commands to set up VRAM amount visible to the system here:

This is the configuration that I myself have for 108GB:
Calculation: ([size in GB] * 1024 * 1024) / 4.096
sudo grubby --update-kernel=ALL --args=‘ttm.pages_limit=27648000’
sudo grubby --update-kernel=ALL --args=‘ttm.page_pool_size=27648000’
sudo reboot
