Hello friends
!My name is Igor. I work at the factory
https://ru.wikipedia.org/wiki/Кpacнoяpcкий_мaшинocтpoитeльный_зaвoд I am engaged in the development and testing of software.
this fall, I, like many of you, took to high profitability d3 and ordered 5 pieces for the October batch,what was my disappointment when the cherished asik came to me!
It's not even about the terrible drop in yield, but about the terrible quality of the devices themselves and the terrible software.
Creepy noise, high temperature chips, thousands of errors per day, high vibration, blade care in xxxx permanent blade of the pools,
in general bitmain pleased with a quality and innovative device!
I honestly tried 2 days,but it's just not bearable!And this is not yet about the eerie drop in yield and the lack of solvency of x11 coins.
I clearly understood that my $ 20k was lost irrevocably,I decided to start the experiments about which I will tell in this article.
It was decided to start with a cooling system, the standard fans went into the trash in their place stood up AFC1212DE(8$ aliexpress.com)
Were also installed anti-vibration pads own production(photo and video of the process will be out later)
In total, this gave the temperature of the chips 61 degrees Celsius at a purity of 524 MHz and the noise level at 62-65 dicebel at a room temperature of 20 degrees Celsius
The next step was to deal with the firmware of our bricks, the side-by-side firmware was installed

that is relatively not bad impact on the stability of the work asik
Yield of less than $ 7 per day I did not like and I decided to go on a complex and risky experiment with a colleague at work, also the owner 3 d3.We made a decision at all to add support for other algorithms such as
X13, X14, X15, X11-Ghost, Quark, Qubit, Myriad-Groestl, Skein
The result of the first experiments was the killing of 1 of D3
At the moment we managed to achieve the work of 1 blade on Quark algorithms, Qubit with a speed of 5600 Mh / s that already gives about $ 25 per day! What would have earned the remaining blades needed to refine the control unit and zany to recombine our hastily made firmware
To do this, it takes a lot of time and money, I decided to quit my job and open a company on the territory of Moscow for the refurbishment of asik
We plan to finish the work on the firmware and control unit for the broad masses in January 2018,
The cost of the new control unit will be around $ 300 without commissions
at the moment orders do not prinemayutsya, because I have work at work until December 13, 2017 time to deal with other people's asik(
I sleep for 3-4 hours a day all the rest of the time I work)An email has been sent Bitmain
with part of my work and a request for assistance in the project, which was refused and stated that all asik past refurbishings automatically withdrawn from the guarantee!Ok Grin
do not rush to sell your D3 at the moment the project is stuck at 60 percent,
the new firmware will be free!
cost of the new control unit as I wrote earlier in the region of $ 300
Next week I will post photos and videos of the work done, at the moment not a normal camera (I use the phone nokia 8800 Grin)
I'm sorry for my bad language Grin
most of the text was written after a night of work through google transliterator

engineerbtcd@gmail.com I'll try to refit your asik out of turn,
Until sooner meetings! Photo and video works lay out orintertrochno December 8-10, if someone wants to participate in the project write to the post address above
