Re: Bitmain looks like they're releasing a 15GH/s DASH miner called the AntMiner D3
didn't found info while googling around so I'll ask here if anyone is willing to help and/or experienced something like this.
couple days ago I managed to build a little farm with ~45 D3s, so far all of them are working nicely except of one,
hashrate drops to 0 after around 10 minutes of working, after rebooting it starts mining on 19Gh/s and then bam and 0. I did try remote steps like resseting, reconfiguring, lowering frequency, etc. but still same.
With my experience in bitmain product in this case I have two options, play with firmware or change the control board itself.
can anyone give any advice?
cheers

I recommend these steps:
0. Check temp, should run at sub 80*C. Any higher and you risk damaging your equipment.
1. Update firmware.
2. unplug for 1 hour or longer
3. Check all Cables.
4. Reset to factory settings
5. Turndown Freq.
Are you getting anything other than "O"s under ASIC status in the bottom right of the Miner Status screen?
I have recieved some D3s through eBay that had issues, i unplugged them, checked all the cables, then did a complete reset, updated the firmware and i have had no issues since.
Would you mind letting us know how your farm is going, Where you are located, what arrangement you made for power, your monthly income, and issues you face running such a large operation.
I run 7 ASIC's in my basement and i live on the East coast of USA, so right now cooling is not an issue, i just had an electrician run additional outlets so i could run all 7, and it runs well. I check on it 4 times a day, and correct as i need.
1. don't want to touch at this point
2. I can do it tomorrow on place
3. I can do it tomorrow on place
4. did it couple hours ago
5. turned down. on 200 it is working smoothly, now jumped to 400, let's see what it will do.
Chips are showing O, that's why I'm sure that boards are OK. If today I won't be able to fix it remotely I'll try physical steps tomorrow and let you all know what happened.
Since my el. fee is 0.7-0.1 Cents mining with those D3s are profitable. In fact I can afford to pay el. fee from my other farms incomes and hold the dash.
you can see all the other things here:
ps. sorry for low q images and dirty work, now everything looks more fancier ))
after couple hours of testing I came to point (freq) from were miner stops working, so after freq 475 the miner stops working.
what can be done here? Maybe update will help?
475 isn't too bad. You should try to update bitmain firmware. They claim it improve stability. The last one is from november. Updating takes less than 5mn, just make sure to backup first.
If doesn't work any better, and you're still not satisfied with 475, give a try to blissz firmware. You can mess up with voltage and frequency per board. Might be able to go a little higher...
I was reading about blissz firmware, I'm not sure that I fully understand voltage-frequency logic, but I think I will have to. In fact that's the last option I will try on this miner. If 1.0.0.9 will do the same (0 hashrate after couple minutes) I will drive to farm and unplug cables for discharge for couple hours maybe.
Anyways thank for your help and suggestions, I will update what will happen
The second miner issue popped up, it's different.
One more question, I've got before October batch S9s and in case of damage I only send damaged boards, what about D3s do you guys send the whole miner or just damaged parts?
