"<unknown>" in windows 10 ethminer 18 alpha3

[evlo]

Hi,

I don't know if you are aware, but in latest alfa3 of ethminer 18 on windows 10, there is lot of, i guess, threads, marked as "".

Everything works, just that it looks weird https://i.imgur.com/ZDvH5h9.png

I can agree there are a lot of "unknown" things and I will try to give some extra informations from my experience. I don't know whats the problem with ethminer output shown as "unknown", but what I can tell you is, ethminer 18.0 alpha 3 version is working on Windows 10 v1809 !!!! . That's impressive ! I was setting up a new RIG last night, with newest Windows updates(nothing disabled) and had a lot of pain, when realizing that my ethminer configuration from other machines wasn't working. All my versions of ethminer closed automatically, before DAG file generation, no matter which extra options I choosed.Seems to have problems with adressing the right gpu because of a CPU with intel igp is present in the system. I was unable to find any tutorial on the web, giving a workaround how to get ethminer working again on win10 v1809 , because nearly everyone is telling you to do a Rollback since problems coming with v1803.But with ethminer 18 alpha3 it's working very stable! I'm using geforce 417.71 driver (without DCH) and I'm not experiencing a loss of hashrate compared to same hardware running on windows 7 machine with ethminer 17. I will give the Nvidia driver (with DCH) a try, to see if there are any improvements or maybe this will fix the "unknown" things. Here is a screenshot from my ethminer output

Thanks a lot to the dev team for making mining on win10 v1809 possible !great job

"unknown" is nothing to worry about. It's only a name of a thread which, apparently, on windows is not set properly. For instance is an async thread from boost library. Nothing to do with drivers.

Will fix but is a very low priority.

Offtopic regarding 1809/DCH - but I did not found any info anywhere regarding it (when i played with it month ago), so I guess lot of people wonder about that:

• 1809 with DCH has exacly same pefromance/hashrate -- worth mentioning here is that system itself with 1809 uses 10W more, but may be related to hw itself as may 1809 test rig has different motherboard then rest of the farm
• lot of other mining sw does have issue because nvml location is different in 1809 DCH version
• DCH version also does not include all the other tools as not dch version (or tools can be found in weird locations :) )
• I did not found any advantage to DCH apart the fact that I could not use non dch on 1809, not that I tried it for more then just running default nvidia driver installer
• there was/is lot of issues that makes 24/7 term mining harder introduced in 1809, especially if you use automated deployment for your rigs -- Still I did not found any way to under volt on linux and the 10% of energy savings is worth it for me (it is even more for other algos)

Thanks for your answers! Of course I noticed that "unknown" is nothing to worry about and I understand the low priority factor absolutely. Just wanna share more information about the ethminer behavior on win10 v1809 with or without DCH driver. I can confirm that 1809 is draining more power than any other platform I used before and I had to upper the TDP for my GTX 1070 to 80% for getting a stable core clock around 1500. On other machines 70% TDP will be enough, but this could be related to model and manufacturer of GTX 1070 (haven't swapped all of mine through the systems). Using 417.71 non DCH drivers will install NVSMI and other tools in standard directory, but nvidia-smi isn't giving full information like in win7( for eample gpu Memory usage = N/A). What about your problem in Linux? I'm using a lot of 1060's with ethOS (ubuntu 18.04) , power management for nvidia cards working good like in previous versions. And with TDP you can regulate core clock. What are the benefits if your are adding undervolt in windows(especially in power consumption) and what kind of software you are using for undervolt?
