Try to upload again the firmware, I have to do it ocne every 10 days to keep the hashpower at the maximum.

It seems to me that if the temps go too high the system disables chips that are doing too much errors, and the way to "revive" them is uploading again the firmware.

Hi all,

I have a problem with my bitmine desk 1 TH
Since yesterday the mining is strange:

in nominal mode: only 4/5 module works !! = about 850 GH
in turbo light mode: all module works = about 1160 GH
in power save mode: 5 module works = about 930 GH

temp is about 55-60 C

Can you help me to resolve my problem please
Huh

I had the exact same problem -- check the fans and make sure they are both running well. One of mine had failed

~nhminer

All fun running well ...

How you do to resolve this problem?

Because all module works in Turbo and Save mode but not in Normal mode
very strange Huh

Upon closer inspection of the board.

One broken connector:

One more burnt out PCB:

I have a burnt pcb too but mine can still work. I fix back in leaving a small gag without touching the heatsink.
I suspect that burnt portion is cause by the heatsink. The temp should be around. 48 to 58'c no more than. 59
Put a box fan or household fan right in front of the coincraftdesk where they are sucking the air . It shild be stable when. You got your replacement.

Thanks, Bitmine.ch are already sending out a replacement PCB / backplane for the one that is totally burnt out which is a really good turn around (Already received the tracking number from UPS).

I'm waiting to hear on the other broken PCB as I don't think the ticket updated last night so have opened a separate ticket.

On another note, the final miner out of my order only has four out of five working ASICs and crashes with a segmentation fault after a few minutes.

And so to the second miner, I opened the case this time to check it over first, and found the control board disconnected from all the ASICs. I have one connector with bent pins and one totally broken connector:

This is now two DoA miners in my batch!

Thought I'd post my experiences of the three Coincraft Desk miners I received today. One of them had a faulty PCB which burnt out as soon as I turned it on (I would advise opening the miners and checking them over for obvious damage, loose connections, etc prior to turning them on):

http://s27.postimg.org/myk7v4oxf/WP_20140521_19_02_31_Pro.jpg

Ticket is open with bitmine.ch about that so we'll see what happens.

The others I am going to check over now and then turn them on, I'll post any performances I get into the thread.

"AND NO HW/ Errors anymore"
Really? Any pictures?

Hi E,

Your table only shows clock speeds. In the advanced Mode there are:

clock speed (Mhz)
core voltage (mV)
spi speed (Kbps)

I am quite a noob when it comes to hardware, could you explain how you set the other 2 variables for the test results you provided and how voltage and spi could affect results? I am reluctant to try without understanding and afraid to brick my miner obviously.

I have a 5 and a 3 module CCD. Heat is much less of an issue with the 3 module version btw. I can run the 3 module stable in turbo ultra with acceptable HW errors if ambient temp is <20 C. The 5 module only runs Turbo Light fine or Moderate if ambient temp is <20 C.

Hi !

i got the CCD 1Ths Desk and my Fault was to Update to the New Firmware ;-(

Whats wrong ?
I tested all the Settings and ONLY the "nominal" works good with 42 Hw Errors per Day.
When i choose Ultra Power Safe and Abov the Miner starts but immed. HW Errors Shown

Same if i get Turbo Mode

Then i switch to "Advance Settings"

i tried diff Settings but ONLY on 850mV+ its OK ( no HW Errors )
when i go down eg. under 800mV the massivly HW Errors , try with 650-800 mhz clock. SPi from 4000-6000-8000

when i change only MHZ and sets to 850mV always the same Hashrate.

Now it try 900mhz/850mV/6000 SPI = after 30 mins no HW Errors and 1100W out of Wall
if i go 850/900/8000 = 1400W

only when i change the mV i get other Hashrates .

Question = have anybody of you the OLD or homebrew Firmware ??
Pls help, cause i will UNDERCLOCK and if i go under 800mV then 1 Slot dont start , (faulty PSU ? )

You can PM me or leave a Link here .

Thx for Help

Glen

Any News for that above ?

@BomberB17 : Did you fix your Problem with your Projekt?

Crocko, I understand your frustration, however this thread is for troubleshooting/technical questions only. Go post your problems in the general thread (official/unofficial)

I have a Coincraft Dragon miner clone, with a Rasp PI that won't boot. I never liked the interface on this miner, anyway, so can anyone tell me if I can use another image to put on the SD card for a better interface with english menus?

IE are all Coincraft Dragon clones usable with the same software?

My target:
Port the whole mineros to another linux distro for the RPi (e.g. raspbian).

Why?
Bitmine's custom linux distribution (yocto) is very minimal, it doesn't have a package manager or a gcc compiler to install other software (like no-ip for remote access, cgmon for automatic restarting if cgminer hangs, screen to observe cgminer running etc.)

My steps so far:
1. Download raspbian image from http://downloads.raspberrypi.org/raspbian_latest.
2. Write raspbian to another SD card using win32diskimager.
3. Copy the whole mineros directory to the new SD.
4. Put the new SD into the CC Desk's RPi (a bit tricky

)
5. After booting, run

Code:

sudo apt-get update

6. Install RPIO

Code:

sudo apt-get install python-setuptools
sudo easy_install -U RPIO

7.

Code:

sudo apt-get install python-smbus

8.

Code:

apt-get install python-pexpect

9. Install latest cgminer (4.3.3):

Code:

sudo aptitude install git autoconf libtool libcurl4-openssl-dev libncurses5-dev pkg-config yasm make libusb-1.0-0-dev
git clone git://github.com/ckolivas/cgminer.git cgminer
cd cgminer
./autogen.sh
./configure --enable-bitmine_A1
make
make install

So after these steps, everything "should" have been set...

But my problems are:

A. By manually running cgminer:

Code:

cgminer --text-only --lowmem --bitmine-a1-options 16000:800000:8000 -o stratum+tcp://nl1.ghash.io:3333 -O bomberb17.worker:1234

it does not run (displays the "starting cgminer..." screen for a second then it exits). Tried without the "text-only" and/or "lowmem" options, didn't make any difference.

B.

Code:

root@raspberrypi:/home/pi# python /mineros/boot.py start
start-stop-daemon: unable to stat //python (No such file or directory)
start-stop-daemon: unable to stat //cgminer (No such file or directory)

(Although by running this command, the fans start spinning and I get the display in front)

So if someone can help solve this, please post! I can also provide link to download the raspbian image with all of the above steps done to save your time, PM if you want it..

so... i build my own CPU 8 Pin to 6 Pin PCI-E....

if somebody need help -> here is a small picture that i made.... that was my "plan"... hehe... it works very good....

no warranty or liability, build it at your own risk!

I received my CPP 1T extra unit today.

If anyone would like to purchase additional hashing modules, I have 5 to sell.

I am in the US. PM "reasonable" offers.
