Hashrate gets down 55% after switching to Dev-pool

[markusmazurczak]

I notices an Issue with the windows version after the miner switched for one minute to mine for the devs:

Even after 30 minutes hashrate stays at 4004 kH/s.

I have this issue on my 980 Ti. Help!

[RLaRock]

Have the same issue with my EVGA 950 FTW. Hash rates almost halved after the DEV mining finishes and it returns to regular mining and it stays that way.

[igloohead]

Is anyone there? Please help with this issue

[markusmazurczak]

There seems to be no further active development of the miner. I used an older Version and it worked for me

[igloohead]

Hello markus, where can I find the older version? Do you have link url?

[markusmazurczak]

@igloohead You can find the releases here: https://github.com/brian112358/nevermore-miner/releases
I am not that sure but I think I used V2.0 or V2.0.1. But you can test it, just let the miner run for an hour and take a look in the log for the DEV-Pool-Switch and if the hashrate stays equal after switching back you got the right version

[igloohead]

Hmm, I'm not 100% sure but even though the display console shows lower hashrate, the mining pool hashrate itself seems to be unaffected. This is on Nevermore v0.2.3

[Cryptominetech]

Mine stalls out completely eventually after switching to the dev pool, just keeps reporting block heights and difficulty but no hashrate.......then I'll get a random stratum disconnect interruption or I'll get pool switching timeout...I've got 3 failovers...using ethOS, latest NVIDIA drivers, and nevermore 2.3, I've changed my intensity from 17-21 and core clock from 50-100, -502 on mem, and power 100watts; in a 13 1060 6gb gpu rig confg....Thinking about switching to hiveos so I may use enemy..If anyone has any thoughts on this please let me know. Thanks in advance!
