I guess this new really shity "Generation 2 miner" are the last hope for bitmine to get back into buisnes.

But their product is so bad plus on top they scammed and hurt so many people it's just ulgy.

After all the scam bitmine did to me (late delivery, reduction of the compensation, selling my hardware to others, ...) I finally rejected all hardware from them and asked for refund. They told me I need to wait 30 days to get my money back .. wtf .. no matter what, 49 days are over, still no money back. They even do not respond to any email any more. Really bad, seems like my money is lost. Again (Virtual Mining Corp did the same thing to me)!

for those who care:
order-numers: 3339 & 4645 (payed with bitcoin)

30 days lolololololololz, been waiting since April 1st STILL no wire refund even though promised "you'll get it in 2 weeks" 2 weeks later "you'll get it in 2 weeks...blah blah" rise & repeat. Scammers keeping our money, lying on phone when you call. F*ck these people seriously DO NOT buy anything from them.

Allright

Since many people asked about overclocking the coincraft desk, here is the magic.

Warning:  try this at your own risk. Do not blaim me or bitmine for these settings

If Bitmine chose to hide these settings, it is for your own good - better to work slow than to selfdestruct.
You will need to place the coincraft inside a refrigerator if you chose high overclocking settings, due to high temperature rates!!!!!!  beware!!!!!  do not play with this stuff because you may damage your unit!

ssh to your desk and input these commands:


root@raspberrypi:/mineros/web#   cd /mineros/web

root@raspberrypi:/mineros/web# vi index.py

you entered the "vi" editor which is a pain in the ass because it has some strange commands:   "/" = search;  ":"=editor command prompt. 

you need to search for the word "locked", so the "/" is used:

press " /  "  and type "locked". just like this:

/locked

and you will be placed at a line like this:

Code:
locked=True

press "i"  (from insert) and type "#"  to comment the line.
under that line, write the new setting:

Code:
locked=False

under that, you will see this piece of code:
Code:
 if locked:
                           sel='$("#cont_basic_mode").hide(); $("#cont_advanced_mode").hide();$("#overclock_text").html("Device speed is factory calibrated to the best possible setting.");...................................(line is longer)

insert a "#" before "if locked" and before the next line

this is how it should look like:
Code:
                       #locked = True
                        locked = False
....................[four more lines with some python language programming stuff related to the "locked" variable].............................
       #if locked:
                        #sel='$("#cont_basic_mode").hide(); $("#cont_advanced_mode").hide();$("#overclock_text").html("Device speed is factory calibrated to the best possible setting.");$("#advanced_m....................[long line, cannot paste]



press "escape" twice, then type  " :wq" and enter
like this:

:wq     (and press enter)

this command saves the changes and quits the editor.

you will be returned to the "root@raspberrypi:/mineros/web#" prompt.

if you are new with "vi" and did something wrong, do not save with "wq".
instead, press "escape" twice, then type 

:q!

and press enter.  this one quits without saving.

refresh the web page. you will be asked again to authenticate.

go to settings -> mining

and some new settings will appear.

Now - I am not too good with this hardware and it costed me a lot of money to buy it, so I chose "basic mode" for overclocking mode, and I selected "turbo light". I watched the temperature on dashboard and LCD for around 12 hours, every 10...15 minutes and I also setup some industrial automatic temperature sensors to alert me whenever the temperature exceeds 55 degree celsius.

Now - it is your responsability if you try what I showed you here. Please do not blaim me if you are not careful and break your machine.

If Bitmine chose to hide these settings, it is for your own good - better to work slow than to selfdestruct.

so the legend is blown away.  coincraft desks can be overclocked. But like every lady, if you do not show respect - then sooner or later either she (or the coincraft) will leave you for good.

Wow.. Thanks for the info.. Do you try to do this? Any result? Pictures? ..

 ..Will it work if I put the miner on a room with A.A. 17°C..?  Huh

I made four screenshots but it seems the picture upload option is disabled and I don't want to angry the admins by tampering with their server settings.

In the mean time I found a way to safely(?) post pictures but I can't preview the pictures in the message, my browser traces some unauthorised https to http redirect stuff to some web site that is NOT postimg.org. Weard. Anyway, both pictures and their links are posted, maybe other people can see them and I'm too security maniac.

here is where all the magic happens.

and this is how the index.py should look like.

To answer your question:  I tried turbo moderate and turbo ultra, and in around 5 minutes the system automatically shut down. The temperature raised higher than 60 degree, also I do not have any possibility for controlled room temperature. I personally go with turbo light.
It may work inside a room with controlled temperature. Maybe all those famous bitcoin datacenters are working in controlled temperature and the units are overclocked. I don't know.

I can only warn you all - do not blaim me if you burn your units - be very careful what you are doing.

sry -> i need a few minuts to upgrade the miner....

the new firmeware has 2 overclock features:

1.basis mode
at the moment i run at turbo modorate and turbo light... because some miner shutdown wiht the higher mode....  (i will test it tommorrow, again)
it can't be a temp problem -> my serverroom is very cool (around 20 °C)

but the hash that the miner indicating is the "right", the pool give's me the same... -> thats much much better than before.....

2. there is an advanced mode

you have to confirm this:


WARNING: Advanced mode will allow you to put the device in operating conditions that MAY PERMANENTLY DAMAGE IT, pay extreme caution when using the advanced mode and follow the advices given on Bitmine's wiki page. If you click OK, advanced mode will be enabled and your warranty will be voided. To abort the operation and go back to BASIC mode, press Cancel now.

for this reason i didn't coinfirm it, at the moment ^^...

the upgrade is very easy and every noob can do this... i didn't get any error...  



tommorrow or on the "long" weekend i will test the power that they need....
(a few minutes ago a made only a fast test -> 2.2 - 2.3 TH -> round 2335 - 2385 watts, thats one in turbo light an one in turbo moderate


Hi Wolke..
How did you do to get: 2.2 - 2.3 TH -> round from 2335 to 2385 watts?  Shocked
What overclock settings did you use?
PSU? Details?
temp?
is that possible??  Huh

I have one Coincraft Desk with 5 modules..

why isn't  Mr. G. Maserati already in the prison ? Are swiss laws really such benevolent to fraudulent businesses ?

My understanding is that you can not easily start a class-action lawsuit against someone or a company in Switzerland. Therefore, it seems each customer would have to sue independently - and this is what they are banking on, that it is too expensive (relative to your order size) to sue them.

The best solution that I can see at this time is to have someone "buy" other people's orders and consolidate a greater number of orders into one lawsuit. That way you'd be able to spread legal costs over a higher number of orders, minimizing the cost and hassle.

Refund Issues - Some - 5/10? Is it a joke ?
Also "using own chips - Yes" is not truth and "communication - OK" is a joke too.

Same here, requested refund April 1st! Anything they say via phone "support" is a lie and a pathetic attempt to buy time so customers get strung along as long as possible.

Kerim is a bold faced liar, and being paid to lie with our money, nothing he says is true.

They give ZERO updates to customers waiting for refunds, no answers returned via email. How can you run a business like this?? Scum bag fraudsters.

Would like to hear from anyone who bought / changed an order to cloud hashing.

The service should be online starting at the middle of August.
