Tnx. I will check the data and the logfiles.
When I run the miner in the console as far as I know it always starts with the card names.. (which GPU are found for mining) In this list it shows 6 times the same (type) cards RX 580
I even had fitted the RX 5700 as a single available GPU, but then I get the miner error "NO GPU for mining"
Is there any known hardware limit for getting the RX 5700 XT's to work in Phoenixminer, e.g. minimum of RAM used, or anything else, which we might have overlooked?
The rig is fitted with only 4 Gb RAM. (We use the Asrock H110 BTC Pro+ mobo)
Perhaps the driver version may be the issue. Do not use the latest AMD Linux drivers for anything other than RX6000 AMD cards.
Well we tried a different (lower version) driver but then we had to change the kernel and still it didnt want to see the 5700 and the additions in the setting didnot seem to work, so this morning I changed to Win10 and we did see all the different cards.. and even the card settings in the confiig file (the RX*580:1160) did work. But we had the 21.1.1 drivers installed and it was not stable. So I uninstalled these and installed the 20.11.
and forced the compute mode via the AMD driver software, but I do not get it stable after a few minutes I get black screens and AMD report of a driver issue and then it all stops???
Probably one of the cards is unable to run at the clocks and voltages that are set. Check the log to see if the proper clocks and voltages are applied to each card - if there is a mix-up and the setting for 5700XT is applied to one of the Polaris cards, or vice versa, it may lead to almost instant crash. The last resort is to check the cards one by one using the
-gpus command-line option. If all are running fine by themselves, you may have issues with your power supply, or the cables to the extenders.
After a while I have found the problem... SATA power for the risers... is not a good combo.. So after changing those the rig was stable..
Now with replacing some of the cards for newer ones we have new challenges... ;-) Thanks for the support.. really appreciated.
