My experience is that compared to other Claymore miners, this ZEC one seems to be least stable in current version.
Not simply complaining; I am grateful to have good miner, and happy to pay for it with Dev Fee, because = stability.
Running 8 gigabyte RX580's, Win10, various drivers;
you mention various drivers?? You should be on the latest AMD drivers with RX580's.. Zcash mining software is very driver sensitive
Thanks for those words. I tried:
b l o c k c h a i n Driver Version 17.30.1029
Crimson ReLive Edition 17.7.2
Crimson ReLive Edition 17.11.4 Optional *currently running
Adrenalin Edition 17.12.1
Have learned, in all above driver cases, -fanmin does not behave the same as Claymore ETH miner. Manual fan control using wattman is required for me with Claymore ZEC miner, but at least fans can be controlled. Did not have to do this with ETH version. Maybe its my vbios customizations having negative effect in zcash mining but not eth mining.. I don't know..
Also learned wattman has new feature to select 'compute workloads' instead of 'graphics workloads', but I only seem to be able to activate it for 4 gpu. Difference seems to be a couple degrees less heat in compute-workload-enabled cards. Hash/sec is within 0.1% across cards.
Also have taken to stop/restart the miner about every 12 hours, and have not suffered hang/reboot in last 48 hrs.
Avoiding miner hang/reboot is good because wattman loses all settings. And since wattman settings are lost, I cannot automatically restart miner (because no fan control.)
edit: suspicious link fixed
