You tell us! Read what Workbench says. I'm guessing it's a 256kb or a 512kb upgrade...
Yeah, my guess would be 512k of ranger c00000 memory. Workbench will say it's fast ram. It's no faster than chip ram, it just can't be used as chip ram. Slow ram is the unofficial name of it.
The A1000 has 256k of chip ram there and another 256k in the front slot. Which I assume is why there is an odd number of chips.
