Wow. The 'under 1kW' result is quite amazing,
thank you very much sharing your method and results.  Smiley

A6 and A7 data communication is not compatible with each other,
and I would definitely put those two generations with a own Raspberry Pi controller unit.

And I would also run A7 and A8 generation miners with a own Raspberry Pi controller unit per generation.

Image is a poorly photoshopped Whatsminer M3. They did a bad job editing out the logo. Controller and other sticker placements are the same.

You're right, lol I just realised this when I now looked at the website.  Cheesy

If it is only a product which they resell or offer for a cloud mining service,
they should definitely change the way they show it at the website  and mention really clearly that it is not their product, it is WhatsMiner M3.

That information only tells me that all four hash boards have entered to a fault mode.

Miner is in the fault mode.

Sorry but I can't figure out the exact reason with this information.

Niko Punin (Head of Product Development) promised the chip supply for GekkoScience projects many many days ago,
hopefully he would still be able to do that and help us little guys.

No solder.

Hi,
I thought that this might be interesting.
Bitfury has released a BF8162B/BF8162B21 Datasheet and it is including a lot of technical information.

BF8162B/BF8162B21 Datasheet - 1 May 2018 Revision: 0.5
http://bitfury.com/content/downloads/16-nm-asic-datasheet-2018-04-002.pdf

They released this while updating their website, now that they have introduced their new brand look.

Satellite internet has a HUGE latency and it can also be an unstable connection.

Bandwidth doesn't matter that much, but for mining you want the best latency available and you also want it to be as stable as possible.

If you are within the city area, I would prefer using fiber or other cable connection instead of the satellite..
469  Bitcoin / Hardware / Re: (Review/Guide) AvalonMiner 821 11.0 Th/s, 1200W Bitcoin (SHA-256) ASIC miner on: April 30, 2018, 11:41:36 AM
@AndyM456
Thanks.  Smiley
Yep. I would like to say that please don't buy a ATX psu.

My two good choices that I can recommend for both A821 and A841:


If I understood you right and you are located in Europe,
I can definitely recommend you this Canaan partner in Vienna, Austria (EU area): www.cryptouniverse.at

If you're talking pros and cons of this miner, difficulty is going to be one factor that's going to influence profitability dramatically. There's competition with Halong as they also announced their own Blake256 ASIC,.. <snip>
Yeah, "Competition". As it is the one and same miner with two different style labelling.  Cheesy
471  Bitcoin / Hardware / Re: Avalon 8 official specs released on: April 29, 2018, 10:54:10 PM
I sent an email to Steven, let's see if they have some lab test info or etc.  which could help to specify the A841 technical specs more accurately.

Hi HagssFIN - Been a week now... have you heard anything back from Steven?

No I haven't heard yet.
472  Local / Skandinavisk / Re: köper miners on: April 29, 2018, 09:16:07 PM
AvalonMiner kan producera Bitcoin eller andra SHA-256d algoritm kryptovaluta.

Jag mina bara Bitcoin med min SHA-256d algoritm maskinvara.
473  Bitcoin / Hardware / Re: DragonMint T1 16TH/S halongmining.com on: April 29, 2018, 08:03:21 PM
It's been 30 days since the T1 has been released. When will the firmware code be released?

Multiple versions were released.

I think he was actually referring to this: when will it be available in Github for everyone to read and examine?
474  Bitcoin / Hardware / Re: My review of Avalon 841 . on: April 29, 2018, 04:06:15 PM
That's some nice additional information for everyone, thanks Phil.
I only had one environment in which I made all the tests for the AvalonMiner.

It seems that the power consumption number is much related to the ambient temperature value.
475  Bitcoin / Hardware / Re: My review of Avalon 841 No Info yet. on: April 28, 2018, 04:02:29 PM
Yep that is correct.

The cgminer command in the 'More Options' field is very important, since the voltage offset function doesn't work without doing so, for some reason.
476  Bitcoin / Hardware / Re: My review of Avalon 841 No Info yet. on: April 28, 2018, 12:57:19 AM
Nice to see some testing.  Smiley

15 mins is quite a short test period.

It looks like that your hash rate should most likely stabilize averaging more than the 13.2 number.

I'm surprised about the 1.5kW power consumption, since my highest measured number was 1400W (voltage offset 0, and hash rate 13.52Th/s).
477  Alternate cryptocurrencies / Mining (Altcoins) / Re: NEW Bitmain Antminer L3++ 596 MH RELEASE MAY on: April 27, 2018, 06:45:03 PM
It is most likely still using the same 28nm process chip BM1485.

And maybe there is even the same total amount of chips.

The only new thing looks to be that it is overclocked a little.
478  Bitcoin / Hardware / Re: Halong Mining announces the T2, a 17-17.5TH+ Miner on: April 27, 2018, 04:37:53 PM
Wow, that was a fast turn-around from the T1 to the T2. I can't wait to do a review!
Actually kind of same type of turn-around that WhatsMiner did with the M3 and M3X miner models (the later one is little upgraded and is equipped with a built-in power supply unit.
479  Alternate cryptocurrencies / Mining (Altcoins) / Re: Need Power Supply for Bitmain B3 (7 PCIe connectors and 328W) on: April 26, 2018, 10:53:47 PM
I think that a good ATX psu is still going to cost about the same as the HP 750W, so why not buy a robust server psu with the same amount of money?

Even the noise level should be really quiet, since you would be running it with only half load capacity.
And also the power efficiency level would be good.

here is a test report https://plugloadsolutions.com/psu_reports/HEWLETT-PACKARD_506822-201_750W_SO-242_Report.pdf
480  Alternate cryptocurrencies / Mining (Altcoins) / Re: Need Power Supply for Bitmain B3 (7 PCIe connectors and 328W) on: April 26, 2018, 10:43:59 PM
Get a Hewlett-Packard 750 Watt server power supply kit.

Like this one here  -->  https://www.parallelminer.com/product/hp-gold-rated-750-watt-power-supply-kit-10-pcie-cables-for-dragonmint-x1-x2/


The bottom line is that you should not go too cheap with the power supply.
You want to have a robust one.
