Hello rdluffy, actually when the app tells me that the rig has died, I do to turn on the screen but it is black so I have to restart it and radeon tells me that it has reset the cards. I have 4 rx 580 8gb and an xfx always 8gb use phoenix miner 5.5c with windows 10. as for amd software I use the 21.1.1 as overclock use mhz 1200 mv 900 mhz 2120 mv 880. I didn't change the bios of the cards. what do you advise me? Thank you very much
The message of Radeon Software reseting the cards is usually because overclock, too much overclock on memory, or low voltage in memory are the most commom
As users already said, try to reduce memory frequency and rise the voltage, then if your system not crashes again, you can refine reducing a little voltage, and increase the memory frequency, little by little.
It's not easy to deal with and keep running 4 or 5 polaris cards, so don't push too hard, and my opinion here is: give more power to your cards to have a more stable system, more time you are online, more gains in this bull market, sometimes it's better to have them running 24/7 with only a few watts more, or even with less Mhs instead of have your rig crashing and losing a lot of shares offline trying to find the sweet spot.
