Are you using the latest version of Phoenix miner?
Version 5.4c:
https://bitcointalk.org/index.php?topic=2647654.0Check the riser cable if you're using one
And the most important, leave at stock settings, 100% power limit, no memory or core clock overclock, and let run for a day
Maybe your card doesn't handle overclock like before
Alternative: you can use Nicehash, and the nicehash miner "excavator", this app will restart miner if some issue happen
Yes latest version of all programs, no riser cable. Yes I was going to try to switch to a product that auto restarts next but that really wouldnt solve my problem per say, just work around it somewhat.
