Do not use Catalyst 16.3! Drops up to 30% on hasharate! You can see the warning on: http://dwarfpool.com/eth#proxy

my 390x's all do about that hashrate for me they run at 30.7 mhs on 16.2 catalyst.. ive tried 15.7.1 all way thru to 16.4.1 hotfix and seems 16.2 is the best for updated drivers.  Issue i have is with a asus 970 mobo that shares pcie lanes.. So my problem at first was getting catalyst to shut off crossfire.. if you load the 16.2 straight from scratch it seems on my system the preference section was missing the crossfire option. So it couldnt be shut off(damn these latest amd drivers are buggy!).. When i would goto the overclock settings it had the two cards linked. So what i had to do was load 15.7.1 and upgrade to 16.2 from that. ok problem fixed with crossfire option.. but i still have a weird lock up issue only present on this system.. It has 16 gb ram 8 core amd 8350 and ssd hdd..  its my home pc/mining rig.  i have 3 290x and a 390x in this rig.. I cant seem to keep this one running and it locks up at random intervals never achieving 24 hours.. I honestly think its the graphics card that i just got off ebay but i have yet the time to try them one by one for 24 hours to see exactly what it is.  Prolly start on that today.  I seen where others are having a strange lockup aswell.. i think if i can narrow this down we might be able to find the culprit.  Those of you that are having lockups.. what are your system specs?  What gpus and associated drivers you running.  Just wondering if we have any components in common that might be causing this.  Im pulling the gpu i suspect is causing the issue and will let it run today and see what i can figure out.


Great work so far Genoil. I for one really appreciate it.. here is a bit to continue work on the miner.  Im sure that even when ETH goes POS   dagger hashimoto is here to stay   

Something for your continued efforts:)  Thanks  Transaction submitted. TX ID: 0x2749d27e76489cc758800c72322edfd84e743b6d47c7855319064386dab22bbf

so what's this?

it seems so, it happened just right now, my gpu are set to zero on the clock and mem after it happen, and i need to restart

i don't think so because my other rig was mining fine, i tried to delete the dag and see , maybe was that the reason, multiple different dag files from different coin may cause issue i believe, not sure though

Where can I find 1.0.7?

It's still source only, no binaries yet. I've stopped releasing beta binaries since a buggy beta was republished and spread. Moreover, I found a strong correlation between people that can build from source and trace bugs . you can find the source in the "107" branch on github.

Hello,

since I switched from ethminer+proxy to stratum-direct with 1.0.6, I notice with almost every new job 1-2 "zero-hashes".
Is this normal or can I configure anything better? My 24h average hashrate seems ok.
ethminer.exe -S eu1.ethermine.org:4444 --userpass (ethaddress).(miner) -G --farm-recheck 250 --opencl-device 0 --opencl-platform 1 --cl-local-work 256 --cl-global-work 16384

Nothing to worry about. In fact, if you use the native stratum, you an safely increase  --farm-recheck to 2000 or higher. You'll get more accurate hashrate display.

May be termination/crash of miner in time of new DAG creation. As I know miner only verify existence of DAG, not the validity.

Cool, I'll try it! But how about switching back to main pool if it back alive?
