Ethminer not finding any solution or submitting any shares

[GigaDroid]

Running R9 380 on Windows 10 and 16.3 drivers never finds any solution.
Same setup is working on Linux just fine.

[smartbitcoin]

if you are not on a pool mining, base on current difficulty, it wont find anything for a long time ( few days).

[GigaDroid]

Forgot to mention I'm pool mining.
Also tried many different pools.

[billprescott]

I am having the same issue. Appears to mine but never finds a solution. Inhave also tried on many pools. Using Windows. Have been mining since Frontier started. This appears to be a new issue.

[billprescott]

Forgot to mention. AMD Radeon R9 Fury X

[chriseth]

Do you have any logs? Do you use ethminer together with geth?

[billprescott]

Attached is the log file while pool mining. It looks ok except that it never finds a solution and submits. The pool does not see the miner even though it look like its mining. Have tried three pools. Solo mining gets the Worker error.

Let me know what other logs you need.

Thanks

Bill

Having same issue on a new rig. Its my only rig using an r7 360 nitro around 4.5mh. I thought it was a connection issue (like duplicate worker name/host name etc) but it's not. Just keeps hashing and burning heat and electricity on its merry way into burning itself into oblivion.. but doesn't generate eth for doing so, or "find shares" on any pool I've tried. Is the low hashrate too low?? Hours at 4.5MH no shares no visibility on pool...

Answered on the new issue you logged, @TheDeafMute, but will echo it here too for the other people following this ...

Have you tried the Genoil ethminer? If not, you probably should. It's had a lot more love that the official ethminer. We hope to upstream their changes back, but for right now they have a better miner.

I just got this EXACT problem resolved with lots of amazing help from Alex at Ethereum nanopool (http://eth.nanopool.org/help). I purchased two Gigabyte R9 380x G1 cards yesterday and installed them to replace a 7870. After installing and updating drivers to 16.3, my pool mining no longer worked.

The solution is to download and install the AMD 15.12 driver. I did an uninstall of 16.3, ran CCleaner to cleanup leftover reg entries, restarted, and then installed 15.12. I ran my same batch files and within a few minutes I was submitting shares and my account was visible on the pool again.

I tried everything I could before this, like different pools, stratum vs getwork, and nothing made any difference. The logs all looked great (except never submitting shares). The AMD driver is absolutely the issue.

Lastly - I had trouble finding a 15.12 driver that was not a web installer (which connects and installs 16.3). I ended up using this one (it's safe) http://www.guru3d.com/files-get/amd-radeon-software-crimson-15-12-driver-download,2.html

Again, big thanks to Alex at Ethereum nanopool, and please send some hashrate their way if this helped solve your issues.

[stephenstroud]

This is also happening to me, I've tried with Genoil but no luck, I will try with the 15.12 driver. Did anyone have any luck fixing this please?

Windows 10
Etherminer + geth

[stephenstroud]

Downgrading my driver to 15.12 didn't solve it for me straight away, but after running ccleaner it's kicked into life. @scmike Thank you! I can finally begin mining for the first time. 👍

[bobsummerwill]

Good to hear, @stephenstroud.
GPU mining appears to be very sensitive to driver support. Glad you found a workaround.

[pmartiamarista]

When you install gpu drivers i recomend to use Display Driver Uninstaller(DDU) http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

[SystemOfSilence]

This can probably be closed. It is fixed in the current release. There is still driver craziness (AMD users stay at 15.12) but is a separate issue from ethminer not submitting work.

[bobsummerwill]

Thanks, @silentsystem.

[sanblch]

I have the same problem. Binaries work perfect: claimore, qtminer. Built from source ones cannot find solution and don't submit shares. Neither webthree-umbrella/ethminer nor qtminer nor genoil/ethminer. I have Ubuntu 15.10 and have already tried both official web site 15.12 drivers, and fglrx-updates from rep.

[bootsiaz]

I have the same issue but is unresolved. Had a worker running for 4 months solid with r9 290 and 390 with 15.12 drivers. I got a rx 470 and installed 16.9.2 drivers (the 390 lost 30% hash rate). Now in that state where it mines but never finds a solution. Uninstalled, ran ccleaner, installed 15.12 again, removed amd folders, deleted dag many times, still stuck in that state. One weird thing is the 390 still has a lower hash rate. Any ideas are appreciated.

[bobsummerwill]

Hey @bootsiaz,

Head to https://gitter.im/ethereum/minercommunitysupport for help.

[bootsiaz]

Will do, thanks.

[stephenstroud]

@bobsummerwill I commented above a while ago regarding this issue and had to downgrade my Crimson driver to 15.12 to get successful mining submits, I recently upgraded my crimson driver to 16.11, however, again this problem persists with the latest driver. The console screens shows mining without errors until I don't see stats being recorded with the mining pool. I'm running on Windows 10, other people I know are experience the same issues with the later drivers on Windows. Perhaps the drivers aren't compatible with the miner. Do you have any ideas how I could resolve this please?

[stephenstroud]

Also the hash rate appears lower when running with drivers greater than 16.

Had anyone encourntered this issue w/ a nvidia card on linux? I see the solutions here are to downgrade the ATI driver, but no mention of nvidia.

I'm running into the same issue w/ my nvidia 1080ti. Official nvidia drivers for linux we successfully installed, and I can see that I'm getting the target hashrate for my card ~30MH/s. While it can successfully connect to and get work from nanopool, dwarfpool, ethereumpool, and others, no shares are submitted. It just continuously tries to compute the latest job received until the next job is received,

Command:

export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100

I have attempted this over the course of a few days to make sure there are not network issues (the main geth client has been syncing the blockchain fine in that time).

Does anyone have an ideas? Is there an easy way to debug exactly whats going on (if the card isn't actually computing the hashes, if they aren't being sent to the sever, if the server isn't accepting them)

Thanks for any help

[aydinhus]

I'm having trouble too. Ubuntu 16.04, Nvidia p100, cuda 8.0, genoil working properly but no shares are submited.

[reppolice]

Having the same problem on GTX 1070 Windows Server 2016, nanopool has not seen a share from me in 30 minutes of running the genoil binary, but still the nanopool "counter" kept increasing in those 30 minutes, no idea how to interpret these facts. The clay dual miner instead immediately gives ETH shares, achieving half of the genoil rate. Strangely the nanopool graph that shows shares as well has recorded some shares, while the HTML table below was showing 0 shares.

[ketetefid]

Oh..I'm not alone! I was wondering what is wrong with my setup and it seems that the miner has some problems. I really had no clue...
GTX 1070 on Gentoo Linux, latest drivers, hashing like a charm but producing not even a cent. It hashes well apparently but nothing appears on the pool stats. Does anyone have a remedy for this? Please tell us a workaround.
I built the miner from the source.

[bobsummerwill]

You probably want to head to https://github.com/ethereum-mining/ethminer, guys.

This repo has been inactive for a year.

[ketetefid]

Thank you bobsummerwill. I will take the advice and see if it changes anything.

[progone]

@ketetefid I use Ubuntu 16.04, I found a solution in the Nvidia setting, this video gave me enough hints to open the nvidia setting via terminal. The video is based on Windows thou.... but Nvidia hierarchy is the same for both systems. Good luck Nvidia Settings

[YanBellavance]

This happens to me when I modify the code and made a mistake. The problem is that the exit condition for work gets overlooked somehow, perhaps skipped or there a conflict somewhere with the threads or the index into data lost its sense of direction
