I vaguely remember reading about a video card that had more RAM than it was able to address.

You may be referring to the GeForce GTX 970. It had reduced bandwidth to parts of its RAM.

Maybe the RX480? Many of the 4GB models sold were actually 8GB models with firmware locking them down.

Definitely not that; the concept was that you had a large amount of RAM you could advertise on the box, but the card was unable to use the RAM. You're describing the opposite, the card has a large amount of RAM that is advertised as a smaller amount.
