your vardiff algo pushes difficulty too far too soon and stays there for a long time, it is almost unusable without static diificulty for me.
This is a test machine i use to check different algos accross different GPUs. ıt has a 1080, 1070 and 1060 can't remember the exact hash rate now, but something like 1.6GH
18DGB in any case almost unreal, the problem is when the diff is over 8 miner can't find any shares to submit until the difficulty drops back. A very rough difficulty cycle looks something like this
3->6->8->6->7->8->7->8->7->8... And these are not equal time periods, 8 takes quite some time, while lower difficulties gets bumped up very fast as soon as miner starts finding shares. So practically miner submits shares at less than 20% of the total mining time.
I am curious why no1 else complained about this may be it is an issue with ccminer or the mixed cards i use or may be both.
I second that, the vardiff is broken. It has far to high difficulty and the re-targeting time seems to take longer and longer. Its unusable with my 6 GPU rig and the earnings halved. Please give us back static diff with some proper lower boundary so we can mine efficiently.
I enabled static diff option again few days ago. Is it okay now?
Vardiff is working as expected but digibyte, myriadcoin's short block time is quite hard to catch sometimes. These coins generate blocks per second sometimes.
I'm seeing no shares reporting for Siacoin, even the the Dashboard shows hashrates and the miner (claymore dual 9.7, linux) is showing valid shares submitted without error... PM account name.
What do you mean no shares? Dashboard is not showing realtime numbers. It may show 0 share even you inserted.
If you get correct hashrate, then there seems no problem.
Thanks. I'll check.
Maybe try this one.

Thanks

Any idea on when Bitcoin exchange is going to be re-enabled?

@miningpoolhub
When are we going to be credited BCC? I do hope you will not delay this one!

Yeah I enabled both currencies. Thanks.
My antminer l3+ will be coming at the end of Sep. I have looked at miningpoolhub. I wonder if anyone has an exact configuration on how to use miningpoolhub with L3+.
Thanks
It's simple.

Some stange things with groestl hashrate on miningpoolhub.
Now i have two 1080ti's cards and ccminer shows groestl hashrate about 106 mh/sec, and myriad-groestl hashrate about 202 mh/sec summary for two cards.
But when ccminer starts on myr-gr algo and works, no myriad groestl hashrate shows on dashboard section of myriad groestl (continuous time), but on digibyte groestl dashboard i see hashrate always between 60 and 80 mh/sec.
Please,check it.
Tnx.
Multipoolminer v2 2.5.3.4.1 used.
Dashboard and Workers page may show fluctuating numbers.
How about checking both pool's Graphs page? It will show what happened in that period with longer time sampling.
When coin switching happens, both pool may show hashrate because your miner would have submitted previous coin pool and current switched coin pool both.
I'd like to ask how often the API value is updated? I see another values (hashrate/workers ...) on website and in API json, in JSON there are old data long time. Looks like it's cached or something like this.
Anybody same problem?
Yeah it's cached upto 30 min.
Anyone have any tips on how to get SGminer to stop hanging during pool switches?
It doesn't always hang but occasionally does. When it hangs I can't even pkill the process and have to walk to the rig and press the power button.

I believe there's some old unstable code in sgminer about pool switching. I also encountered some hanging when I mine more than a week.
That's why I prefer --no-retry option than internal pool switching.
I recommend you to ask to tpruvot about this issue.
Anybody, please, check your hashrate in ccminer of myriad-groestl algo on miningpoolhub digibyte-groestl or myriad-groestl dashboard.
Now I have only about half hashrate value.
For example: ccminer shows 200 mh/s myr-gr algo, but i can see only about 60-80 mh/s on digibyte-groestl dashboard.
Not 30-35%, but 55-60% hashrate dropping.
Is it normally or not?
Hashrate on the dashboard is only an approximation
Of course, but in other algo hashrate on ccminer=hashrate on dashboard plus minus 35% maximum.
In my case, it was minus 60% continuosly.
I think it is very strange, IMHO...
hashrate is an approximation but it should not be consistently half or less than half.
This is happening due to, "vardiff" algorithm being broken (at least for ccminer at the moment) and feeding miners "too high" difficulty targets. as a result, you submit no shares = no income, until vardif drops the difficulty.
pool operator also said (i think 1-2 pages ago) he disabled vardiff for some reason (some people abused it? can't really tell)
Big tnx for your answer!
Maybe you tell me how i can adjust difficulty for normalize this situation?
Ccminer have some options like -m (diff multiplier) or -f (diff factor), but nothing happens with change this values.Maybe you advise me about these values?
When miner starts, the pool set difficulty 0,450 and "reject low difficulty shares" message shown.
How i can change difficulty, or its impossible?
It shouldn't show "reject low difficulty share" whatever vardiff or static diff is set.
Maybe try -m diff multiplier to make difficulty level correct first.
Hi all, I have create a website to monitor multiple coin in one screen for MPH, feel free to try it

pls pm me if you have some comments on it
Thanks.
can you add bcc to autoexchange?
Yeah I will enable it soon.
It's unstable network still. Only 0~2 blocks per hour.
can you add bcc to autoexchange?
I have had three different coins stuck in autoexchange for over two weeks. Nobody at MPH replies to my emails for help. Why would you want to attempt autoexchange and have stuck coins?
Most times auto exchange is stuck due to low volume. If you auto exchange with same coin more, then volume will be met and traded correctly.
Or I just recommend you to auto exchange to bitcoin or ethereum which has enough volume to be auto exchanged.
I flush stuck coins manually occasionally about 2~3 months interval.
Sorry for slow email replies. I get many email messages daily.
Also some email message can get into spam folder without notice. Please leave your message at bitcointalk or Skype instead. Email is not that reliable.

The auto exchange to Bitcoin is working for all the coins. Bittrex just needs enabling for BCC.
it is enabled already, and 0,0003 is way too high TX fee for a coin with empty blocks...
0.0003 number came from bitcoin.
I have no idea how much actual txfee will be needed. Fee is automatically calculated from bitcoin-cash wallet currently. I see quite similar fee level from bitcoin-cash network.
ZEC manual cash out not seen on blockchain and wallet for more than 10 hours...
What is your id? I'll check.
Question to MiningPoolHub:
It looks like my Musicoin vanished into the ether, or rather it did not vanish into Ether but simply just vanished.
I opened an account to use for test mining and mined a little Ether & Musicoin, then decided to transfer Musicoin from the wallet using the "Transfer" option to "Credit for Auto Exchange" - having first set up auto exchange for Ethereum, but it looks like the Musicoin just vanished - maybe I'm mistaken ?
It's no big deal if it's all gone, just like to know where I messed up.
( I've an Ether address but don't yet have a Musicoin address set up - could this be the problem ?)
Here is a screenshot of the Transaction History. My user ID is 100449.

22288104 Debit_MP and 22288105 Credit_AE is matching transaction.
Minus from normal credit wallet and plus to auto exchange wallet.
So there's no problem with that.
22289478 Debit_AE means Debit for Auto Exchange. Your 2.097536689 Music sent to exchange site for auto exchange.
It will come back to Ethereum pool after few hours.
I belive you already received that.
My coins have been stuck in auto-exchange for over two weeks. It is not a large amount but it should not be doing this. I have tried emailing support but they do not reply. Someone from MPH please address this issue and fix it asap.

What coin did you set for auto exchange? Have you checked O, X from auto exchange page?
I belive changing exchange coin to bitcoin will solve it.
