Picked up a couple of these. I remember using them years ago in an SE or Classic maybe. I don't recall. But I do not recall if they let one "bypass" the theoretical limits of the hardware. For example, an SE/30 can address a whopping 128MB of RAM. But the processor can, technically, address up to 4GB. So would stuffing eight of these bad boys with 16MB SIMMs allow 512MB of RAM?
