Hey guys , first review and problems:

First of all miner is better and more effective by 2-3 % than EWBF. I've been running it on several machines , got improved hashrate  (GTX 1060  3gb from 280 ~ to 300 ~ , GTX 1070 from 470 to 490 , GTX 1080 from 540 to 550 , gtx 1080 ti from 720 - 740  , all vary bettwen + - 1-5 sol/s)
Machines are working fine with ETHcontrol , or anykind that has some watchdog that either restarts miner or knows what to do. But so far they are running stable.


Problem :

I got one rig with 7 cards and it seems that it cannot work good with dstm miner. It has 5x 1070 , 2x 1060 3g


First of all , to run it properly I had to lower power limit ALOT on all cards

Standart settings at afterburner:  80 pl / +150 core / +540 memory  -----------> at this point miner and Ethcontrol comes in some loop that whenever miner is started it's always killed and restarted , because it hangs out too much time or shows 0 sol/s for cards (e.g. miner takes a lot of time to start and doesnt start at all)

Settings to start: 65 pl / +150 core / + 540 memory -----------> miner starts but this is what happens , after "1round of hashing good" it starts hashing super pooorly. I dont know what should be the case , all my rigs are identical , just this is the only one with more than 6 cards. All have same windows / drivers etc etc etc . CPU seems to be stuck at 100% at rig 1 though when I run ZM miner , probably some problems with more than 6 cards rig on win 10 ?


edit: I've tried a lot of different settings but in vain. Problems seems to be that  POWER for cards makes crazy jumps (35-80 % PL for example) . Only time it worked fine for arround 5 mins , was because power limit somehow settled down at exactly 80 % (what was set) and it was running okey. Making any changes to OC settings results in various jumps in power and thus cards start to hashing super poorly. This is the only thing i've discovered.

Thx for the report, this is very helpful.

I'm currently heavier on CPU load.
It looks like your CPU is to slow to provide enough work for the GPUs. CPU load increases with the total solution rate of your system - so this is most likely why your 7card rig is having troubles since it requires more cpu time. What CPU are you on?

It's intel 1151 , G3930  , it's not impressive but it's not on the downside of any processors.

edit. I got such processor on all my machines , and also planning to add up to total of 8 cards on each of them soon , so this might be huge problem to run ur miner @ them
