"insufficient memory for DAG epoch 414 will be in zombie mode with reduced hashrate" error

[king1267]

I just installed and set up lolMiner and it works for the most part but my hash rates are really low considering I have a 4Gb RX580. Can someone help me figure out how to fix this error? Along with that, my worker does not show up on etherminer.org. I checked and I have all the right ports and pools entered but it shows up despite it saying connected to us1.ethermine.org:444 (TLS disabled)
