4GB card RVN Zombie Mode?

Hi Folks. Been reading a while but this is my first post. I've got a 1650 (non-super) that has been steadily going at RVN for about a year now but I seem to have just hit a wall in windows. The miner keeps erroring out. I'm guessing the DAG is to large (3.29GB) with whatever windows requires from the GPU for me to keep mining RVN. I was curious if there was a zombie mode for kawpow I could utilize for a little while or if I just need to switch it to ERG or ETC? I could also try HiveOS and mine a bit longer before 4gb is too small but its my only 4gb card so I'm not sure its worth the trouble of switching right now.
