Topic: Innosilicon's A4 Dominator, 1.2W/Mhs 14nm ASIC and miner, open for Partners - page 7. (Read 48989 times)

sigh then how come my Alchemist miner runs at a steady 137 to 146 on five boards some times higher pool side like it should, this one barely hits 128 most of the time stays around 121 to 124 and shows at the miners UI 137 to 138 MH, you want Screen shots, i can give them ."as you will always lose a little on stale shares and such".< I'm very a ware of that but not like this .Id be happy with  130 to 132 pool side, best it hits pool side is 128 unless it's nice hash.
 and Innosilicon even told me in a email they are aware of some pools under hashing which it seems now might never be fixed like the Alchemist was. if i mine Lite coins on Antpool id be lucky if it hits 110 mh while my Alchemist miner runs @ 134 or higher it all depends what pool it is for the A4 . I'll bet the L3 + runs around what it suppose to any place . which i hope to have A L3+ soon i may post Screen shots once i do . I guess what i should watch more then anything is pay out which i don't ... . i was able to improve the speed and shares some the other day by giving the miner full api Access by editing some files in the controller with SSH .

When will the next Batch of Miners be shipped ?

We have come to a result after many negotiations, complaints and discussions with a lawyer. The point is that they do not really care how the order arrives. I received an asic with a nonfunctional board, to which I was asked to pay the repairs! Finally they sent me a new card (today I received the courier information) together with a controller. From my own experience, they are very bad at communication.

Hello
Have a problem yesterday had a power failure and since that connects my a4 miner is no longer with the internet can help me someone thanks.

 You have unrealistic expectations.

 You NEVER will have a long-term match on "miner side" reported hashrate and "pool side", as you will always lose a little on stale shares and such.
 Doesn't matter what miner you use or what algo, this is the norm on EVERYTHING in crypto.


 Pools report your hashrate poolside based on the VALID SHARES you have found.

 Variation is ALSO normal, due to that fact.

I received a couple of the later miners (which have individual heat-sinks) where the heat-sinks were loose in the case (they'd fallen off in shipping, one of the boxes had clearly been dropped), and Inno sorted the problem out straight away once I'd sent them back, sending me new hashboards. Time Zone and language barriers aside, they are always very helpful when I've dealt with them.

There's a critical piece of information missing from your post, what kind of power supply are you using? These Inno boards are well engineered and extremely robust, so if they're burnt out it suggests there may be a problem with either the boards circuitry or the power supply, and Inno are very honest in my experience so I personally think they'd say if they had found a problem with the boards voltage regulation.

Might be an idea to check your PSU before connecting it up again.

In the middle of May I bought an A4 Dominator ASIC, arriving on June 2, but with problems:

Hi, today I receive the miners, but is a problem. At the web interface are 4 miners, one of them work at half of normal (33-34 mhz) and I have a maxim 210 mhz on nicehash and under 200 on digibyte. Tomorow I will make a printscreen to tell me how so solve the problem. Thank you.

Hi Marian Danut Corduneanu,

Our technical support feedback says that the incorrect operation caused the board to burn out from board you sent to us.

Pls pay attention, electrical equipment can not plug connection line when it is running. The damage caused by it is not covered by the warranty.

So you should pay for it and shipping fee. I apply it to our manager, we can give you a twenty percent off discount.

One board is 320 USD.
Shipping fee for one board to Romania is 132 USD.
Total price: (320 +132)*80%= 361.6 USD.

Feel free to let me know if any question. Thank you.

The board arive from you broken, check when I received it because I immediately announced that. Do not try to blame me, I would have broken the whole asic, not a single board. You come with the proof that the plate has worked for one minute at me and I broke it, and I support the expenses. If not, you replace because is your fault, you shipp a faulty board!

Hi Marian Danut Corduneanu,

Don't worry. We can solve it.
Confirmed with our technical surport, the damage caused by misoperation normally burn the whole chips, some times burn one board.
Considering the inconvenience caused to you, we can repair the board and replace the 10 chips. And send back to you.
And it will cost 150 USD. shipping fee is 132 USD.
I apply it to our manager and our A4 sales team, we'll give you 20 percent off. And you only need to pay 220 USD to us.

In reality, our machines are all tested before we send to you. We guarantee that there is no problem like burn one board.
There is statement in invoice i sent to you: that the circuit boards or the chip is burnt is not covered by the warranty. You can check it.
Considering your side feedback problems, we can repair it.
Pls understand. Thank you.

Dear Marian,

Thanks for your purchase of Innosilicon A4 Miner.
This is Dominique from Innosilicon, Business Manager of A4 miners.

There must be misunderstanding between you and us for the board replacement within warranty.

First we feel very sorry that you get the miner with only minutes running then a board is broken. We don't know what happened on your side but could imagine how sad you were.

Then we ask you to send the board back to us to investigate if the board can be repaired. If the board is broken slightly we will send a new one to you soon to make you get the full machine asap. But unfortunately we found that 10 chips on the board is burnt which cannot be repaired. We are very sorry to tell you in this case the board cannot enjoy the after-sale service within warranty as written in the invoice.

So we have found a better way to lower the expense on your side by providing 20%  of the total price($150 for the chip replacement, $132 for the shipping). Normally we would ask customer to just send the board to us without the heavy heat sink(the metal) to save the shipping fee. It's our fault that we didn't remind you in advance. We are very sorry about that.

Innosilicon is a big company which has served thousands of customers, aiming to help customer solve the problems.
Your case is really sad but we are trying to help at any time.

We don't want to let you feel bad to us due to such a board, so we will only charge 50% of the total price, which is $141. You can pay us in LTC or BTC.
What do you think? Your understanding will be appreciated.

Best Regards,
Dominique
Innosilicon A4 Sales

No, unfortunately you do not understand and refuse to provide me the required report. The board did not work for me for even a second, that's why I asked the technicians report with the minutes of operation from the date I picked up the parcel. I'm not interested in the payment, the board was broken, it did not work at all (not even a single bit!). The other three boards have been functioning properly since we put them into operation. Please beg your respect for not coming up with price offers, because I have to resort to the court and then come with the required report!

Dear Marian,

Thanks for your feedback.
What we are doing now is trying to help you to get the issue solved. So please calm down then we can reach an agreement soon.

We have attached the pictures that you have sent to us.

1. From the minitoring page of boards, there is a label "none" which shows only around 33Mhs for the board - > in this case that means half of the chips(10) on the board is broken.

2. From the chat history we found that you have switched the plugs from one groove on the controller to another when the maching is working - > this is misoperation( operation of hardware connection of a working machine is prohibited )

3. Attached is the screenshot of the multimeter when detecting the chip voltage - > normal chip voltage should be more than 1.75mv while your 10 chips shows less than 1.7mv(this means the chip is burnt which cannot be used any more)

All in all, the chips on the board is half burnt when we received the pacel. And as written in our invoice, if chip is burnt then the part cannot enjoy replacement free of charge.

We have offered our suggestion to help you repair the boards asap and get the board shipped to you with a lower repair fee. And we have already mentioned that we will cover the shipping to you.

Innosilicon is a big company which has served a lot of customers with the A4 miner. We have tried our best to help you solve the issue. If you still want to go to the court, then we can also face it.

We are ready to ship a new board to you once we received your payment. Please feel free to let us know if you need the board shipped asap.

What you gave me is not the required report. I asked you a report of the minutes since I got the asic! You do not understand one thing, you sent a plaque with half of the burned chips! The pictures you have attached to me are pictures of the conversation and prove that the board did not work, no matter what it was (the first pictures and the last pictures)! From the first e-mail, after I put the device in operation, there was dpvada that the board came with the burned chips!
I asked you to extract a report with the minutes of running (how many bits did that board use to mine), from the date I received the asic!

That conversation I wore when you got in touch with the technicians. The asic was disconnected from the power source, and the ports interchanged. At that time the board did not work, if it happened as if it was under tension, the other three boards were burning.

If you teling me that half of the cip from board are burn out, prove the board arive with that problem. Never work in mine and at the web interface show half of the power, because the cip was burn.

It's been more than a week since the board is at your side and I do not see any results! So you treat your clients? Is this the serious business with you?


NOW, MY QUESTION -
Is there anyone else ho buy from them with malfunctions? If someone has broken ASIC into a warranty, how did you do, how did they behave?

2.10 still doesn't do much on sites like Zpool , litecoin pool or Prohashing.com .. it works  great on nice hash but I don't care much for nice hash ..
and it is the same issue, it show it mining at 137 to 138 MH miner side and on the POOL side on some pools it some times only goes as high as 120 to 128 never a good sable 138 or close, on Zpools it sets at 80 to 84 MH pool side but in the miner on the UI it shows every thing working fine and Ming at 137 to 138 MH steady but sense i can mine Zcash on Zpool and get paid in Zcash, without using GPUs but can't,  i hope it stays that way but from time to time it's nice to get paid in that coin even if your  not really mining it with a script miner i know that..  or get paid in any coin they support with any miner type which lets me use old miners if i want to like my A6 ...which lets me also justify using my A6 and that A6 has a second wind use for a while longer.


Just asking ? ...... any big fixes coming any time soon for the Poolside hash rate issue on some pools or does that need to be another more up to date re flash of the boards like jstefanop did here https://archive.litecointalk.org/index.php?topic=27370.0 for the AlcheMiner/MAT Miner that was having the same issue till he fixed it, will the A4 see a even newer updated to make it more stable and if so when will that happen ....

I know i still own and use one of the AlcheMiners .... and the fix for the A4 now doesn't seem to work for all pools like his did for the A256.

Again if I use my A4 on Nice hash with 2.10  no issue so far , it's on other pools, i have the low hash rate issues  with any version....of the miner software....

Those numbers are from the initial announcements of the A4.  Original test video of the A4 showed the chip by itself is capable of some impressive numbers, but apparently those hash rates were not able to be maintained, or there is something in current packaging etc that prevents these chips from running at rates that it looks like they should be able to run.

Now if Inno were somehow able to correct that and release a miner with those stats right now they would be back in the game and would be competitive.  If they were to make that kind of announcement I would be more than glad to setup another group buy here for the community with Inno's help to get these miners in the hands of the community.

Inno please keep us posted or PM me if you find a way to get these kinds of numbers from the A4.  I would be glad to help you here in the community.  I would love to see some competition for Bitmain.  We have seen Inno will stand behind their product so we know it will/would be a good miner. 

Unless there has been some shadow upgrade, the A4 get's around 250-260MHs at about 1KW.
The current webpage shows pretty much similar numbers...
http://www.innosilicon.com/html/a4-miner/

Miss type ? . ....just noticed that !!!! if it's not why doesn't my tube get results like that ... any way I'm gonna buy i hope buy two more tubes soon ;;;;don;t care much for bit mains junk it cost 3k or wait till July .

I just set up my first A4 Miners.

Initially I had a lot of trouble understanding exactly where to change IP addresses but thanks to Innosillocon skype, finally sorted it.
Ea mining setup consists of 2 barrels. These generate about 60-65 db of noise.

So I have decided the only way to go is to set up my mini farm in the garage.  My small office was not enough space to get rid of the heat with the door closed.

Best results yet occurred at night with a peak of 1Ghash between two miners. (4 barrels) but not for long. Mostly runs between 500 and 600 MH for two sets combine score.

We have decided to build a noise box around them, and to rid exhaust by a powered exhaust fan connected to a whirlybird or such the like.
During summer I think we will apply a small thermoelectric aircon.

Whilst it is economical now, i wonder how much room there is to remain profitable enough to at least pay for the electricity if there is a lull in price.

howzit for u al out there?

If you should need 2.0.3 this might help you:

Anyone from Australia who knows the limits of how many A4s can be powered per room circuits in Aus? what is the limit?

Better to contact Innosilicon through email ([email protected] <- taken from website of innosilicon http://www.innosilicon.com/html/a4-miner/)

Or use skype, the address is on the website as well

Back in Nov/Dec I had these in my garage, and I have a time-of-use plan, so I had a switched-PDU and automatically shut-down the power between 3 and 6pm to avoid the high rate.
Never did anything formal to shutdown, just shut-off the outlet at the PDU, and back-on when it hit 6pm.
Miners restarted fine from this "yank" for 2 months, and although I have since moved them to a datacenter, have had no side-effects of the daily power bounce.
Still runnnig smoothly, but now 24/7 instead of 21/7 at home.

Yes, I went back through my wallet and found that I am almost 2x my purchase price, so very happy.

Works for me. Thanks.

You're probably close.  I just hit break even this month which was far better than the track we were on in December and January!

Proper? Yank the power...
