I am having problems with a RX 6800 XT, it gives me driver time out error after 30 minutes , 10 minutes, 2 days so it is random.I have 2 of these cards and one Nvidia RTX 3060 Ti and I am using this latest miner 5.5 from Phoenix.Is there any solution to this ?
The RX 6000 cards no NOT like the default Mining Intensity.
I use -mi 4 (-mi 1:4 as it is my second GPU) on my RX 6800, it fixed the stability issues 100%. Depending on your build a different value might work better, I just lowered -mi on the card until the hashrate began to go down, 4 was the first setting that made it go down just a hair (about .5 mh/s), and it works AMAZING!
