Need help with Nicehash

[Steve Sokolowski]

Do you notice that these issues occur periodically, after long intervals? For example, is there a disconnect every hour? Or, is hashrate lower all the time?

[Steve Sokolowski]

I wonder if this issue has to do with the extranonce.subscribe feature that I've read a lot about. There is no documentation what its purpose is or how to implement it, and I have yet to be able to find anyone who knows anything about it.

From my observations the level of lost GHs is NOT dependent on:
- location of NiceHash servers Europe, USA
- rented GHS level. It was equally bad yesterady with 0.1GHS and with 4GHs
- the number of rented workers. I tried startingofrom 2 ending with 45.
- price per GHs. I tried to pay more than minimum in order to be on top of the list hoping to get better quality workers.

Unfortunately have no clue yet about the positive dependency list

I'm connected now the same story as yesterday

Speed at pool 1.1346 GH/s
Speed paying 1.4242 GH/s
Delta -0.2896 GH/s (-20.34%)

Would you be willing to try using a password of "c=litecoin"?

Compare the results of that with what you have without a password and we'll see what you have. Is your username the same as on the forums, so I can look at data in the database?

Thanks for your help, by the way. I'll make sure you are compensated for your time.

Yes, my username is paszokonik.
Password c=litecoin alone is not passing NiceHash's pool verifiction.
Set r=0.2 d=16384 c=litecoin and started 1GHs using US servers.
At the moment I have two batches of 1Ghs the second one is from Europe with r=0.2 d=16384.

I can send you screenshot of charts after some time of operation

Here you are 30min stats

US batch http://images67.fotosik.pl/1271/b4edf8f905bc8567med.png

Final results of GHs percentage loss
US servers litecoin 8%
Europe servers bestcoin 14.6%

I'm wondering if these figures are simply a result of Nicehash misreporting the actual hashrate.

I'd like to know how they obtain those figures. They don't have the actual miners onsite, so they can't simply query the miners to get their hashrates. The only way for them to get those numbers would be to look at the shares coming in, and if they were doing that, the figures should be exactly the same as what we print out. That would even be the case if work restarts were causing hashrate to decline.

The other possibility is that they are simply printing out what the sellers told them the hashrate would be, which is probably always promised higher than the seller actually provides.

Could you see what these numbers are at another pool?

Just started 1GHs from Europe NiceHash to HappySatoshi EU servers.

After 10 minutes surprise delta is positive

Speed at pool 1.1561 GH/s
Speed paying 1.1430 GH/s
Delta +0.0131 GH/s (+1.13%)
