If I try and start it without putting the tray in the freezer it fails to boot and the red light comes on. If I do this it boots fine and runs for a good five minutes before the second processor (B) warms up, I get a red light on the tray and the machine shuts down.
In order to get the dual processor tray to work, I have to put it in the freezer for half an hour before fitting it to I have a single processor tray which works fine for practical purposes but I also have a dual processor tray which is where the challenge arises. Its running either Snow Leopard for legacy compatibility or Mojave when I'm in a flashy mood. This should be an interesting challenge for you guys.
