It's Saturday and Eureka I found it. Found what you might ask. I found the solution to Clamore miner not working. I recently got a new Rx 570 video card to put on my second rig and have had nothing but trouble with it.
As I'm still new to this mining thing I'm not always sure what I'm doing which is off the case in most every day. For starters I'm using minergate to mine Monero and I've read the discussions on it being a scam, tho I have doubts. It, rather they, they seem to do what they say they do but I digress. Using their GUI miner was fine with nvidia cards on rig one. On rig two where the RX 570 resides, the Gui doesn't notice the card and declares GPU mining not available. Bummer indeed. So I ran through the checklist:
Drivers installed? Run lspci -nn | grep VGA
yep it says so but still getting errors of no device.
Read, read, read. Hmm ... Guess I'm going to have to try Claymore Miner. Found it. Got it. Ran it. Error. No openCL . Great. I'm not one to give up. So in keeping this post as short as possible let me say:
I tried install reinstall drivers, install reinstall OS, downgraded versions of OS, downgraded versions of kernel, install reinstall everything in triplicate. Still nothing. So in the end I found if I ran just the command to start Claymore with no parameters it suddenly started mining on some other address/account. Ahaa. Found it.
According to the instructions you got to use a file called epools.txt ...but the other address was a dead give away so a quick look back at the instructions and a look at the file config.txt and viola. I replaced the info in config.txt with the info to my account and ran the command nsgpucnminer with no other variables or parameters and low and behold I'm mining with my new GPU at a nice hash rate of 604h/s using pow7 - cryptonight
Woo-hoo. So I guess what I'm saying in this post is don't quit. Don't assume anything. Try everything. Look, look, read, read and you may find it's simpler than you think. If only I had noticed it before all the uninstall reinstall that would have been nice, but hey, it's working and I learned a good deal of vital info.
Hope this helps.
