guys third gpu shows 0, any ideas? thanks
I have two miners running Win10 as well. This happens for me when the AMD driver crashes on a particular card. I will get the error from AMD and when I look it may have 1 or 3 cards that are mining at zero.
When this happens I have to fully shut down the miner, bring it back up and then I can use it again. A reboot will not work in this case. (it appears to hold on to the problem - as if it requires the video card to lose/drain all power)
I have a separate box running LinuxMint - trying to see if I can't run it the same, but it doesn't have (or I haven't found yet) the same way to boost the cards as I do in Windows.
If you start normally with that card it means it is a driver problem and so far the only miner which restarts after 10 second with the same settings you had mining normally before the crash is NBMiner.I had a lot of problems with Phoenix,lolminer and a few others with the RX 6800 XT-s I have and since I switched to NBMiner,when a driver crash happens from AMD I only lose 10 seconds and I am back again running with the same overclocking settings.I don't know how they do that but I think it is an absolute must nowadays that all the other miners implement this.Both Phoenix and lolminer continue to mine with 0 Mhsh when a driver crash happens until these versions and this is a suggestion I make here for them to fix the issue for the AMD cards.
