Only 3.2GB avail, mining suspended. nVidia 1650 super 4GB. RVN change?

Hello, was hoping to run this by you all to see if something changed with Ravencoin.

I have been mining through ethermine flypool for months now with this card, all of a sudden yesterday, I get the message that there is only 3.2gb available and mining has been suspended. The GPU itself is completely free and clear before I fire up the miner.

Any insight into this would be so appreciated! Thanks!
