I'm getting errors from video cards.
If anyone can help, I appreciate it.
I own, Intel i7 processor, 20GB Ram (16 + 4), 5xNvidia 8GB memory per card. Using Miner CryptoDredge, and after 2 or 3 hours you will get an error as per attached image.

Error Message: "cuda error: out of memory in cduMem :: create (45)"
[21:13:00] ERROR - GPU1 stopped working due to a critical error
