Innosilicon releases A9 Zmaster 50ksol/s Equihash miner at 620W

[Andartis]

...
I'm ready to listen u , if have any solution <3

Thanks

Power off completely?
Check cables and PSU.
Factory reset?
Apply firmware again.
Disconnect hashboards (power and connection cable), try to boot controler only.

If nothing helps, ask inno support.

Concerning return times after warranty, my D9 hashboard is 3 weeks on its way now, still did not arrive. At the chinese customs at the moment. I sent it with DHL.

Talk with your shipping service before sending these out. Since it's for repair you should be able to avoid importing delays while they sort out if you should pay customs or not.

Hello my friends,

I have some problems
I have 3 A9 Zmaster and since today 1 of them stop working.

He can't mine anymore. He search everytime...
I have reboot... Re-install firmware, check connection, reinstall equipment..

I'm ready to listen u , if have any solution <3

Thanks

Got to do all the basics, to rule out every thing. Start with power and adequacy. Then work your way though each board separately and cables. Try other boards with other controllers, etc. Rule out everything you can. Since you have more than one unit you can troubleshoot more.

You don't even have to open them up just connect the the 18pin to the other controller, you can use a 4pin to usb adapters to power the fans on secondary unit.

FYI, I'm on a D9, but most of the software interface is the same. Last night I found the "stats" cgminer api to obtain the details of each chip (e.g., nVol, Temp, PLL). I think the values that come back are not in the units that we'd like (e.g., temp = 505; maybe correlates to 67C), but I think it would be worthwhile if someone did this for the A9 and measured the values in each of the different modes. I plan on doing this (maybe tonight) on the D9. Hopefully there's something that correlates so that we can figure out if altering the .conf file is having any remaining effects.

can you please explain how you accessed the "stats" cgminer api?

The cgminer API is available through the use of JSON RPCs. Early on, I created a python script that I made to monitor my ASICs before I knew about AwesomeMiner. I used sources like this (https://gist.github.com/WyseNynja/1500780) as a starting point and expanded from there. Premium versions of AwesomeMiner may be able to do the same thing with sending these commands.

If you do a search for "cgminer json rpc python", lots of different projects come up that you can use to hack together a solution.

[sweeperAA]

For the D9, I'm the process of obtaining the .stats output for each of the different tuned profiles (e.g., efficiency, balanced, factory, performance). Looks like I'm only going to get to a couple tonight as it's in the "tuning" process. I hope to have a map of all the values and try to correlate, at least, the PLL values in the next couple of days.

hmmmmmmmmmm...weirdness...not sure how to translate these numbers and why it says falsefalsefalse, but then true....

   u'VoltageBalanced': False,
   u'Voltage Avg': 860.0,
   u'Voltage Max': 872.0,
   u'Voltage Min': 850.0,

this is in volts... 0.872V is your max core voltage. like i posted before, the asic datasheet spec says optimal core voltage is 0.90V +/-10% so this can be bumped higher for the people who want to play mad scientist.

   u'VoltageBalanced': False,

i think this indicates your 3 asic cards are running at different core voltages, so some tuning of the VID for each chain will be necessary.

try changing T1PLL to 1325 and see what the u'PLL #'s come back as.
Also, try bumping T1VID up to 175 to see where your core voltage sits.

if there is more to the printout can you please post the entire thing next time?

BTW you have a typo in your config,
  "T1VID1": "170",
    "T1VID1": "170",
    "T1VID1": "170",     you are setting the same variable 3 times

[wKiV7378U]

A day of hashing zencash back at the autotuned performance mode shows more stable performance on my miner.  No dips below 40ksol, whereas when I set the PLL clock higher before, I would dip in the 30s.  Sometimes I see spikes into the higher 60s...
The poster Hawkfish a few pages back has a much more stable A9 than I do...unless it has something to do with the pool I am mining on?

Right now the only mod Im using is fan speedup, I think any overclock will need to optimize VID with PLL based on what I can see. https://i.imgur.com/cbF3gQq.png

oh you're right. thanks, kind of invalidates test I was doing.

I noticed that if I have  "T1performance": true,  then the clock speeds I set don't seem to stick. Looking at the scrolled logs they seem to revert to 1250.

Took apart a bad (50%) Hash board. I was hoping for something obvious to stand out. Nothing did. The boards where quite nice. Solder looked nice.  Heatsinks are screwed down and easy to work work. Thermal grease on the backside and Thubber, Thermal Rubber, on the tops. Replaced thubber with Arctic Silver, may have dropped 1C, hash rate wasn't noticeably better.

I'll post photos in 12 hours.
Probably will troubleshooting a bit in a few days when I'm free. Check th voltage to hashing Chips's, bypass some chips and see what happenes. Hopefully borrow a flir IR Camera and have a look. Any experience floating around that could send some ideas my way?

[bitliteethdashneo]

Does anyone have pricelist of manufacturer for Innosilicon A9 ZMaster.
My miner is holed up in airport for about 2 weeks now.
The DHL looks like its in collusion with customs and is finding out pricelist of manufacturer,
sending trace to origin and whatnots.

Regarding pricelist - its a method to determine cost of equipment when its not manufactured in imported country
and rest methods fails.
- search for method 5 in the below link.

Using regular thermal paste in ASICs is generally not a good idea. Because of the 24/7 workload and the high temperatures, it tends to dry out quite fast and loose good contact. You will need to replace the paste quite often. The pads also dry out at some point but still have good contact.

can you post a picture of the asic card?

ive been wondering if off-the-shelf water cooling thermal blocks might fit on the chips

also i dont see any correlation between asic temperature and hash rate speed.  before modding my fan, my asic cards sat at 70C and still hash with the same efficiency sitting at 50C.

Pretty certain I'll make the entire life of the Miner without changing it. I wouldn't call 48C that high. In retrospect, It wasn't worth the effort Todo though, as it didnt make a big difference and things will be messy if I decide to pull off the chips later. Just wanted to be sure I wasn't dealing with one hot Chip destabilising the chain.


WkiV: pics are coming in 4-5 hours.

They're not as good as I'd hoped. My camera really let me down. Wish I used my Phone, lol.
