Hello, I know that Collin Minster, aka dosdude1 knows how to upgrade soldered on ram and gpus vram and upgrade graphics cards and stuff like that. Can someone find a bios for me for the iMac 21” early 2012 to upgrade the gpu from 512mb to 2gb? I have no idea if it’s gddr5 version or gddr3 version. And I have no idea how to check eaither.
