In Linux, you can set it as high as you want, although you should probably have a swap drive and still be prepared for you system to die if you set it to 128GiB. Here's how you'd set it to 120GiB: # This is deprecated, but can still be referenced options amdgpu gttsize=122800 # This specifies GTT by # of 4KB pages: # 31457280 * 4KB / 1024 / 1024 = 120 GiB options ttm pages_limit=31457280
