If the miner is put in a room with environment temperature of 35 degree Celsius, what will the core temperature be?
Are the fans PWM or will their speed stay between 3150-3450?

[QuestionTime]

So have these knock-off chips been reported to Chinese authorities?

Joke of the day.

we will test in future, but the temperature won't be very high as we suppose

Miner arrived today as claimed by pcfli. This thing screams like a jet engine, and weighs as much as one.

Will have to replace with something quieter, and I thought the Antminers were loud.

Also, for US people, have a spare PSU AC cord rated at 10A or greater for a 1000W PSU, the original AC cord is China CPCS-CCC (Type I). Luckily I had an extra EVGA Gold 1000W PSU not being used, so I used the cord from that.

Interface is all in Chinese, but luckily when on, the front screen tells you its local LAN IP. Thank GOD for Google Translate, I had it configured and hashing in less than 5 minutes once but pcfli supplied documentation beforehand.

Hashing at 1Th/s as claimed on Eligius:

I will post pics and a full review later today.

All you need to do to change to english is change a single PHP file on the pi

can you post more info on how to do this? links, etc.

Thank you

While you can change a single PHP file to make the interface in english there were a lot more problems than that present. For one there is not autostart/autorestart and the cgminer process was started directly from the php button(BAD). I ended up completely overhauling the interface based off of some other cgminer php UI files floating around https://github.com/jameshilliard/28nm-www . Whoever made the stock GUI and pi image did not really know what they were doing IMO.

Prochedure:
ssh into raspberry pi using the IP on the screen or an ip scanner, its IP should be between 192.168.1.1 and 192.168.1.254
default username is "pi" and default password is "raspberry"
you can either use sudo to make these changes or just make a root account
To make a root account:

Code:

sudo su root
passwd

then enter your password
you can then use a GUI tool such as winscp to move files around
copy or clone my git repo to /var/www
you will then need to place the startup scripts and other files in the right places
simply follow the matching paths for my var opt and etc folders from the root directory and place those files in their respective folders
you will need to chmod all of those files in var opt and etc to 755
you will probably need to chmod /var/www recursively to 777
you will then need to run:

Code:

sudo update-rc.d S99cgminer start

you will probably get an error but it will still work after this command
From there you will see the new webui with minersource in the top left hand corner.
Please submit a pull request if you come up with any improvements, I hacked this together in about 12 hours so I'm sure I missed some stuff. Currently it will not set a webui password properly, although you couldn't do that to begin with, that should be an easy fix but I just haven't had the time to go through it. I haven't figured out how to get the IP to update on the screen either with the UI I made.

$3899 for the S2 is higher price than individual S1, but they adjusted for energy savings, still not cheap!  But no competition.

Hey,
Would you be so kind to answer my pm?
Thanks

Does anyone know how to overclock these units?

[Dalkore]

Can someone link to setup instructions for accessing the device and manually configuring cgminer.    In the future, any company selling hardware needs a support thread that has information for setting it up, you really do your customers a dis-service noting having that ready.  Thanks.



P.S. I tried to SSH into the IP on the LCD screen and it is not accessible. 

[HashingHitman]

Hello,

Nice, thanks.

So, what are your impressions now that you have tested the dragon?
