Is everyone who was doing these boards gone now?
Seems it's impossible to find them

Well, sidehack is still going on strong.  Smiley

So a question... Anyone thought whether it will be possible to run an 821 on the same PSU that a 741 was running on... One of the HP server PSU's and DPS-1200-FB-1A - on 240v?  I think on paper the 741 and 821 draw the same wattage don't they?  If so, then it should be feasible.
We know more about that after we have seen a actual power consumption measurement.

I'm planning to power A821 first with Sorcerer psu (Canaan custom psu) and then with DPS-1200MB-1 1400W server psu and then compare those power consumption measurement results.

What is the default frequency for these again? Is it 525?

It is 600 MHz.

My mains voltage was 220 VAC when I did a thorough testing and review for the Whatsminer M3,

you can see my results in this review thread https://bitcointalk.org/index.php?topic=2390138

See chapter 7, Power consumption measurement.
845  Bitcoin / Mining support / Re: Line-line 3 phase power isn't working on: January 29, 2018, 02:47:16 PM
Are you able to measure your mains voltage at home and your mains voltage at the warehouse?

Measure the voltage before and after plugging in the psu. So you can make sure that the breaker has not tripped.

It would bring some more info to our troubleshooting.
846  Alternate cryptocurrencies / Mining (Altcoins) / Re: Launching the Antminer L3+, World's Most Powerful and Efficient Litecoin Miner on: January 29, 2018, 12:23:53 PM
True. I have unfortunately not found any usage hours calc in the Antminer.

If somebody has more info how to find it out, please share that info here.

I also agree you Albortz on your later part of the post.
847  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: January 29, 2018, 12:59:38 AM
So that would be a 10000BTC risk at stake at the moment.
848  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: January 28, 2018, 11:59:03 PM
The danger that they created for themselves is now people can follow the money. 6k is a lot for some people, enough that they're going to have to look over their shoulders for the rest of their lives.

well no one sent me a btc address with payment to dragonmint.

So I can not  do anything to trace  payments backwards or forwards.

Maybe elokk could help you out and send a btc address they have used for payment?`

I sent him pm.

Here is an example picture of the Cube miner. You can see the CE marking there, after the model name "BAIKAL Cube V1.4". https://imgur.com/nqVMfZS

thanks HagssFIN I will take another look
I think that is not the correct CE marking.


http://mondos-porco.blogspot.it/2015/12/la-cina-falsifica-il-marchio-ce-europeo_15.html

You are correct, they have printed the 'C' and 'E' too close together.

It looks more like the bull shit 'China Export' marking.

So I stand corrected.

We have no 100% certainty that the Baikal cube actually has a legit CE conformity.
851  Alternate cryptocurrencies / Mining (Altcoins) / Re: Launching the Antminer L3+, World's Most Powerful and Efficient Litecoin Miner on: January 28, 2018, 10:07:02 PM
Is there any way to tell how long a miner has been used? I'm about to buy 2 L3+'s off of a guy locally and he said that he has mined with them for a month but I really wanted to check and see if there is a way for me to tell.

If you ask for the miner serial number, you can check the order date here https://shop.bitmain.com/support.htm?m=technicalSupport

See "Warranty Check".

If anybody is interested in buying an L3+ Jan batch for 0.3 BTC + shipping send me a PM. I prefer selling to another forum member than going through ebay.
Some tips...

I recommend you do a proper sales thread in the marketplace computer hardware section.

Photos of the hardware with a piece of paper and your name on it.

And be ready to accept payment through a escrow service.
how the escrow service is happening here Huh I am selling antminer A3

After the seller and buyer have a confirmed deal,

1.  Buyer sends the btc payment to escrow agent  (OgNasty or philipma1957 for example).
2. Buyer sends a personal message as instructed by the escrow agent  (OgNasty has his escrow service thread for instructions).
Make sure that you have two recipients for this message, both escrow agent and seller.
3. Escrow confirms that he has successfully received funds and he says that he will release after buyer has confirmed that he has received the goods in a good condition.
4. Seller sends the goods to the buyer.
5. Buyer receives the goods and confirms that they are in promised condition.
6. When escrow agent has received confirmation from the buyer, he will release the funds to the seller.
7. Trade complete.  Smiley
854  Alternate cryptocurrencies / Mining (Altcoins) / Re: Antminer A3 only has antpool as alive. Sia and luxor shows as dead on: January 27, 2018, 10:57:59 PM
What did you do to get it to work? Mine are showing as dead too. (Unless its AntPool)

Are you sure you have typed everything correctly and also typed a port in the stratum server address?

here is an example (siamining pool)

Quote from: example
Pool 1
URL  eu.siamining.com:3333
Worker   your-siacoin-wallet-address.workername
Password   x

Pool 2
URL  us-east.siamining.com:3333
Worker   your-siacoin-wallet-address.workername
Password   x

Pool 3
URL    us-west.siamining.com:3333
Worker   your-siacoin-wallet-address.workername
Password   x


I'm mining just fine at Siamining pool with my A3 unit, no issues what so ever
855  Bitcoin / Mining speculation / Re: KryptMiner - 20th/s @ 800w (a new magical miner / scam?) on: January 27, 2018, 10:31:01 PM
We need more people willing to take the risk so that others may not have to.  

I disagree.

We need more proof and transparency when a new manufacturer enters the market, so it will be less risky from the very beginning.

Even though Bitmain is not the most likable manufacturer at the moment,  they are still a good example entering the market as a new manufacturer  with a solid discussion thread here at the forum with the Antminer S1 back in the 2013  https://bitcointalk.org/index.php?topic=330665.0

Jag kan rekommendera den 3D printet adapter om du vill användä luftväxlingrör i din system,
den slutresultat skulle vara bättre än utan en adapter.

Du kan hitta några exempel videoer i YouTube   https://www.youtube.com/results?search_query=antminer+soundproof


857  Bitcoin / Hardware / Re: GekkoScience is now dabbling with 16nm ASICs for new designs on: January 26, 2018, 11:20:30 PM
No news currently. The last I heard from Bitfury, chips were sold out until around Halloween.

But Bitfury's not the only game in town. We might see a little magic yet.

I'm just gonna go ahead and enter few wild guesses here about the ASIC chip manufacturer  Cheesy

BW.com? Canaan? Pangolinminer? Halong Mining (if they are real)?  Ebang Communication?

Question already asked, Can i re-use an old Pie first model with the 821 software or a Pie 3 is necessary ?

Yes, there are three versions of the A821 OpenWrt software.

One version for the Raspberry Pi 1.
One version for the Raspberry Pi 2.
And one version for the Raspberry Pi 3.

Next time, please buy the Bitmain APW3++ power supply and it will be much easier for you, as you don't seem to know that much about psus.
860  Alternate cryptocurrencies / Mining (Altcoins) / Re: Using evea 1300 with new Antminer a3 on: January 26, 2018, 11:59:11 AM
Thanks you really helped me! But don’t I need 3 cables to each board in the miner and another one for the controller board? Means I need 10 cables. In the picture you showed only 6 cables

Am I wrong here?

If those pci-e power cables are at least 16AWG wire gauge, then you should not have any issues.

The wire gauge information is printed of the invidual wires.
