Mining: GPU0 is out of memory

Hey all, I'm a bit stumped on this one. I have three separate mining rigs each with a 4GB video card. About 2 months ago one of my 1650 super's stopped mining due to an error message stating "GPU0 is out of memory" Watchdog restarts after 10 seconds and I get the same message. Today, my second rig suffered the same problem. That leaves only one miner left mining. Below are the things I have already tried based on previous users posts:

1. I have tried adjusting the page file to 8GB +
2. I have uninstalled and re-installed the latest version of gMiner
3. I have made sure my storage drives are not full
4. I have updated any and all drivers (Windows found no updates for my GPU's)
5. I have fully uninstalled and reinstalled Windows and repeated the steps above.

Am I missing something here? As far as I know Raven should still be mineable on 4GB cards, I mean it's mining on a 4GB card right now on my last machine. Any thoughts? Also, in case it wasn't clear, I am using gMiner. Is this a known issue with gMiner as of late?
