This could be a stupid question, but as an idea:
Will it be possible to use same the Raspberry Pi as I'm now using with Avalon 6, to control these units?

Wow, some nice setups in this thread.
Here's my setup:
  • 1x Avalon 6 with Silverstone Strider Gold Evolution 1200W
  • 2x Antminer S7 with 2x Bitmain APW3-12-1600 1600W
  • 1x Antminer S2 with Enermax Revolution87+ 1000W
  • 1x Antminer S1 with Super Flower Golden Green SF-500P14XE 500W

Shelf and a DIY soundproof cabinet:


Closer look on the Avalon 6 and Antminer S2:


2x Antminer S7 inside the cabinet:

Sorry to hear that, talks_cheep   Undecided
Any error log?
How are the temps, 12V input?


I got the Avalon 6 today in perfect condition.

It's a perfect add to my setup, I'm now mining with total of 14TH/s.  Smiley

I'm really pleased with this group buy and that SANYO fan was a real cherry on the cake!

Thanks a lot, Phil!

Here's a pic of it next to Ant S2:

Response:
Yes of course. the general release of the new miner is sure to be, but the timing is not yet known exactly.
Our staffer, who deals with these issues now is not in the office.
as will appear more detailed information about it we will tell you, the main thing that you reminded about it in advance

Original message:
Hi! Is BW going to make a general release of the newest (14nm?) miner like
Bitmain has made with Antminer S7 and Canaan Creative has done with Avalon6?
Seems like it would perform more efficiently than these miners above, which
would be great news for miners.

HagssFIN ---  has cleared customs in Finland

I'm still waiting for Posti to send me the arrival ID needed for that customs clearance, which I can do online at www.tulli.fi .

Please do another group of avalons!!

I'm furious I missed this one.

The one regret i have with these is my particular unit will only perform to spec if feeding it a platinum rated EVGA and believe me I used 2 Corsair AXi's both 1200 and 1500 versions neither seemed to ever consistently push those all important 12.v

If I power my A6 with anything other than this EVGA 1200 Platinum it usually starts strong and by 4 to 6 hours in it's dropped down to 11.8v and by 10hours...forget it.

It's down to 11.7 or 11.6 and I'm avg 2990Gh/s it's weird.

I guess it might be due to my inability to provide it with a 220 outlet?

Whatever the convenience of the 4 PCI-Es and the dramatic noise level difference are really appealing in comparison to my pair of S7s that squeal like Victoria Azarenka in a 3rd set tie break.

Honestly I can hear them half way across my house.

Phillipa please pm me if you get the go ahead from your contact for another round.

Thanks in advance ;-)

MichaelC

I am waiting for pricing info from kilo17 and yan.

I also have

r00t$ gear due to him on Mon-------------- 1 unit IL
biffa 's gear due to him on tue-------------- 2 unit's U.K.
hagssFin's gear due to him this week ------ 1 unit Finland

 

So I would not start until tues  so hold your funds  figure close to same pricing 650 maybe less.


Posti (Finnish postal service) has received my shipment and it is at the customs in Helsinki. I'll make the customs clearance as soon as Posti  gives me the arrival ID.
I'm guessing that I'll get it in Tuesday

Try this calculator and see it for yourself http://tradebtc.net/bitcalc.php

It is hard though to guess difficulty change% for each adjustment, BTC price, etc.  Undecided

While way hugely early, there isn't any indication of a huge increase coming this time around.

Bitcoin Difficulty:   158,427,203,767
Estimated Next Difficulty:   165,685,950,107 (+4.58%)
Adjust time:   After 122 Blocks, About 19.6 hours
Hashrate(?):   1,218,052,943 GH/s
Block Generation Time(?):   
1 block: 9.7 minutes
3 blocks: 28.9 minutes
6 blocks: 57.9 minutes
Updated:   16:0 (8.4 minutes ago

If the hash rate at the moment of difficulty change is ~1218000000 GH/s, difficulty rises approx. +7.4%
If the hash rate at the moment of difficulty change is ~1220000000 GH/s, difficulty rises approx. +7.58%

How I came up with this estimate:
Based on history, difficulty divided by the hash rate (GH/s) equals approx. 139,69838.. and it has been about this way through the difficulty history.

139,69838 * 1218000000 equals difficulty of 170152626840
139,69838 * 1220000000 equals difficulty of 170432023600


yeah but  that  1218ph  is not for the last 1850 blocks.  by the way it would be good for you if it where as your guess was  7.5 iirc Grin



here is the best "real time"    lazy number


https://bitcoincharts.com/

Blocks   403094
Total BTC   15.327M
 
Difficulty   158427203767
Estimated   165490408235 in 106 blks
 
Network total   1103595.192 Thash/s
Blocks/hour   5.84 / 617 s



divide  16549 by 15842 = 1.044628  or  4.4628% jump with 106 blocks


the best 'real time' number is

2016/336 =  6  that is zero %






so I think block 401194  was the first block  this diff jump

401194 (Main Chain)   2016-03-05 00:31:41
403095 (Main Chain)   2016-03-17 16:17:52

so 1901 blocks in 304 hours 20 minutes should be 1826 = 4.11%     I am not sure and need to check this




I checked and got  this

401184 (Main Chain)   2016-03-04 23:25:56
403096 (Main Chain)   2016-03-17 16:30:08


1912 blocks in  305 hours  should be  1830  

 so 1912/1830 = 4.48%   with 104 to go

Oh, yeah. I didn't notice that it was an average of last 504 blocks.
So the hash rates shown in the history are always an average of 2016 blocks?

So the theory stands the same, but I got the hash rate numbers wrong.

3777  Bitcoin / Hardware / Re: Antminer S7 with single DPS-1200FB PSU on: March 17, 2016, 12:03:53 PM
Hello,

did anyone tried to power single S7 with this PSU, it is rated at 100A = 1200W 12V output on 220V network (I am from Europe so this is what I got at home).

S7 specs says it consumes 1210W from the wall, so it is quite close.

Maybe if I downclock it a bit it would be fine?  Anyone tried this?

...

From bitmaintech.com:
Quote

S7 Specifications:
1. Hash Rate: 4.73 TH/s ±5%
2. Power Consumption: 1293W + 10% (at the wall, with APW3, 93% efficiency, 25C ambient temp)
3. Power Efficiency: 0.25 J/GH + 10% (at the wall, with APW3, 93% efficiency, 25°C ambient temp)
4. Rated Voltage: 11.60 ~13.00V
5. Chip quantity per unit: 135x BM1385
6. Dimensions: 301mm(L)*123mm(W)*155mm(H)
7. Cooling: 2x 12038 fan
8. Operating Temperature: 0 °C to 40 °C
9. Network Connection: Ethernet
10. Default Frequency: 700M


It is more like 1400+ W at the wall.

Anybody ever run into a situation where you are missing a fan in the GUI? fan is on, though at a really low level and cgminer shows no fan for fan1. Bad fan? Bad board? Thanks in advance!

Dead fan, the other one is moving it.

Good point, hadn't thought of that. Got any recommendations on replacements? I know they can be had from bitmain but that takes too long. Anybody see an issue using this fan from amazon?

Ok, nice to hear! Again, thanks for doing this Phil!

I am in the process of testing your unit .
I swapped the stock fan with the sanyo ace fan.

The rasp pi works
the little adapter dongle works.
here it is mining ........

Okay, nice! Just got today for a reasonable price a used PSU, Silverstone Strider Gold Evolution 1200W ready to hook up with A6

Since you are in Finland I want to be sure it works.  It will get packed tonight and shipped tomorrow.
I will go online to double check that psu that you mention to be sure it works.  well for this unit.

Ok, thanks.  Don't worry, I'm an electrician  Wink

It's quite reliable brand PSU with nice output of 1200W (1300w peak), one 12V rail.

I checked Avalon A6 specs here: https://ehash.com/product/avalon6-v6-0/
