Use as username: WALLET . WORKER_NAME

how can I enable worker names in case of dwarfpool i'm confused

can't wait till the next version maybe it will be corrected

Did you try AMD's Wattmann tool instead?

If that doesn't work take a look at this:

In my case Ethereum miner disabled faulty GPU. In your case it says "ignored", so I don't know what to suggest. Maybe you don't have -tstop option, so it ignores it instead of stopping and logging.

version 9 better than 9.1 in terms of spike power
testing your rig (use chrome open(use shortcut on taskbar) & close (use alt+f4) repeat it until power spike come and yur rig will shutdown)
 


claymore need to fix this, lol

Nothing in GPU hardware error logs? (hwinfo)

actually version 8 will only run at 200 h so it is not profitable. your statement is true if I have to up my psu to get 220 does not equal more profit

Yea perhaps. However it doesn't say which GPU it is.

Had this with ETH dual miner when some 390X card was overclocked too much. It is a hardware issue.

Any of you get

After that speeds are all zeros and the rig freezes and needs a hard reboot.

Hi,

Fanspeeds stuck at 20%

I tried:
-tt -70
-fanmin 70

What to do?

I used public forum when I had an issue with shares. After that I posted details in PM, shares were recalculated and the issue was fixed (not for me only - for the EU server users, it was an accident case when stitching data from worldwide servers with Ethereum).

Also when my friend had an issue with CoinMine, he created a ticket using pool site and did not receive an answer. Then I post a PM to pool operator on forum and received almost instant reply that solved the issue. I don't like that, but seems that social networks and forums sometimes provide better support than emails/tickets. Don't ask why, maybe due to public nature of those requests...

I use it with ASrock H81 Pro BTC board, it has 6 PCI-e slots, one of which uses this splitter, and two cards are connected via it. So 7 cards in total. All 7 are Sapphire RX470 Nitro+ 4GB Hynix memory, and all 7 mine at exactly same ~212 Sol/s. This rig uses Windows 10. I've heard Win10 can use up to 10 cards, I do not know. I had issues with RX470 cards with Win7, no patch helped, 5 cards were maximum, the rest did not work at all (even 6th). Now I use Win10 To Go booted from USB flash, and it works perfect. It also works great with Linux. No drivers were installed by hand, Win10 found the PCI-e bridge automatically and installed GPU drivers.

That's exactly why few people wrote here that hash rate race is not good if no explicit reasons for that since it does not increase profit but decreases it due to power bills. No one listened, now it is the result: more power, more expensive PSU setup, etc. And not more profit :-)

Don't mix a warm with a soft (mining with shopping). When ETH dual miner was created, Claymore changed its default intensity from 16 to 8 to save few ms only. These ms cost some stale shares since after share is calculated, it should be delivered in time. Using -i 16 created larger jobs from CPU to GPU which can't be stopped until finished, and even those ms were important. Now we talk about Zcash, it has slower block time, but solutions itself are huge comparing to ETH ones (around 1300 bytes vs 50 for ETH), and all this now is encrypted in addition. So you have exactly the same case, but for some reason no one is concerned with it like it was for ETH.

Someone tells no one will see their addresses via SSL. If you are paranoid, you should not use exchange addresses. Install zcashd, mine to t-addr and move all to z-addr, send to an exchange t-addr, and no one will know who you are. No one except you will even know from what z-address funds came to the exchange. This is what Zcash was created for. You do not need SSL for that at all. Use right tools for particular task. I understand that 90% people here are home miners, they never read about Zcash: what is it and how it works. Still, it provides 100% security if you are paranoid and use it right. Without any encryption or closed source. That is the brilliant part of Zcash that is undervalued yet.

I used NiceHash when I had no time/wish to watch Zcash prices. Since its orders were paid for current Equihash (ZEC/ZCL) prices depending on the market, NiceHash paid in BTC more comparing to mining a particular currency (but took 3% of that in BTC before payment, that's a lot). Its customers watched for better algo, switched to it and paid more in BTC.

I actually hopped between CoinMine and NiceHash because when the payment rate @ NiceHash was high, I mined there and received BTC. When the payment rate was low, I mined @ CoinMine to exchange Zcash later.

I tried and stopped using automatic pools like MiningPoolHub because it does not give you exactly what you expect. It selects an algo for its instant profitability (network difficulty, current price, etc). But after you mine it, it matures, moved to an exchange, things may be quite different. So I preferred NiceHash when it paid well instantly, and CoinMine, when price was low (to sell when it goes high).

Now I left CoinMine, one of reasons is its PPLNS system since Dec 8th. It works bad in such scenario. Never liked PPLNS and always used DwarfPool for ETH. So CoinMine lost my hash rate instead of keeping it, since as said, PPLNS is not good for hoppers, and there is a reason for it as explained above.

I like DwarfPool due to its full stats and ability to talk to operator if you have questions. Every share is logged, so any issue always can be fixed by recalculation. It is small (because it did not enter Zcash race in time). It provided 50% to 30% of Ethereum mining, but only 2-3% of Zcash at the moment. The more people will use it, the less will be variance in payments.

Of course, people already shout here about missing SSL - I've heard it is in progress on DwarfPool. I use it just because I like it as it is.

verson 9 is useless it power down my computer so it is time to move to something else since it is not profitable with version 8

- reduced devfee, it's 2% now (72sec instead of 90sec) if you use secure SSL/TLS connection, currently Flypool and Suprnova pools support encrypted connections, see Readme for samples.

Guess what - SSL won't help you for that. Whoever captures your traffic he will know you are mining. Just you address and number of submitted shares will be concealed to certain degree. Shares you send could be recognized

SSL helps here against traffic capture. You will reveal your account number by other means. Your wallet can be stolen by software running in your computer, not by capturing your miner's traffic.
