I'm having to link these from my Google Drive, since this forum does not seem to allow directly uploading a picture. One of these shows the "more options" for 1.16.5 that shows the place to increase the RAM, another shows the "less options" for the Forge installation, and the last shows the identical "more options" for Forge - it does NOT show any place where the RAM can be changed.
