Oh, and having more then 2Mb of chip RAM would most likely break a large amount of software, perhaps even AmigaDOS/Workbench (now commonly referred to simply as AmigaOS) 3.x may have trouble with more then 2Mb of chip - I don't know and the only people who might really have an idea are those who have worked on the Amiga operating system or have at least viewed the source code to it.
Don't think so as Amithlon defines 8mb as Chip-Mem !
This was don because many apps still use Chip-Mem when
they are fully rtg-compatible.
