Hi guys, looks like a perfect topic to my issues..
I have 8 x RX580 Armor OC 8Go. (Hynix)
I download "Apolyon's " custo rom from Anorak and went from 20Mh/s to 22.5 Mh/s and download the AMD Blockchain drivers and went to 28.3Mh/s.
I know a lot of users getting better results but I would be satisfied with thoses if everything was stable...
BUT .. I had a lot of freez (random.. something after 5 minutes, sometimes 5 hours..), so I had a look on HWinfo and two card were making errors.
As the "Armor OC" version, Overclock a little the CPU, I decided to underclock it again to "1200Mhz" instead of "1366Mhz" out of the box.
Three Options to underclock :
- Msi Afterburner : Must of the time just freez the graphic card.. I also ready that AMD block the possibility for external software to underclock GPU, only Overclock is allowed..
- Claymore parameters : As I am using Claymore to mine, we can set parameters to set gpu setting like -cclock 1200 . But Again not working..
- Radeon setting Wattman : This solution is working fine !! but after few minutes/hours I have "Watchdog GPU xx Hangs in OpenCL" in claymore (which restarted), but then Wattman reset the GPU clock speed to default.. and lead to freez the computer avec minutes/hours..
I am very upset as : The settings "out of the box" are not stable to mine. And Radeon Wattman is not stable with multi GPU. This is written by ATI in the "know issues" of the drivers...
So does somebody have a solution to make this RX580 Armor OC 8Go stable ? Rom / drivers / OC appreciate.
Once again, i'm not even trying to Overclock.. but just downclock to make it stable..
