Hi All...
Some recent posts 1 2 have re-ignited my curiosity for upgrading the VRAM on GPU dies that have multiple-VRAM variants (usually the workstation/PRO cards have double the consumer versions).
Nvidia cards seem to use the same standard practice as laptops/macs: resistor straps.
However, I can't find much info on AMD boards? Some seem to suggest it's purely in the bios, no resistor-shifting needed.
Just wondering if anyone on here has any experience with this? Or any schematics, etc.?
