The standard quick pry with the fingers (and subsequent pull) frees the RAM from the logic board.

Our $599 mini shipped with only a single 1 GB PC3-8500 chip. In this configuration, the NVIDIA 9400M graphics processor allocated 128 MB of this memory as VRAM. When we installed a second chip in this machine, for a total of 2 GB, the 9400M automatically allocated 256 MB VRAM instead.
