some more information/screenshots/photo would help...
Which psu?
All modules connected?

hello i have a problem with 1 module not responding ? plz give me help i have 1 th

if i remove the -quiet options of cgminer,

I see a lot of:
[2014-05-04 12:58:10] 3: chip 1: invalid nonce 0x1ff7815a
[2014-05-04 12:58:10] 3: chip 6: invalid nonce 0x1145d4a2

[2014-05-04 12:58:11] 4: chip 6: invalid nonce 0x5f4565da


what does it mean?

is anybody in an p2p pool ? -> the miner runs 50 - 150 gh/s lower is this pool.... GRML...

is there an solution ?

if it has apt: yes

Look here :

https://bitcointalksearch.org/topic/technobit-hex8a1-260ghs-coincraft-based-miner-reviewed-476970

I choose 226GHS cause its the Best Setting for GHS/Wattage and with the correct Firmware its almost 230 GHS


Glen

Perfektly !

You are the Man !

will download an try it tonight

Do You think its Possible to control the CCD with another Raspi ( Minepeon ), via USB or Lan  ?
cause i use Minepeon with the HEX8A1 and its damn good

The SD card image can be downloaded from:
https://mega.co.nz/#!pVtGGCwD!z_L2dMPP1Zl9VuvJLqZIkOyxTltyQUMdIGEyD7pW64E

can be used for read/write with
http://sourceforge.net/p/win32diskimager/wiki/Home/.


*****************************************
Advice: buy an extra SD card 8GB for this purpose,
dont use the original.
*****************************************



What I have done is basicly make an tar copy of
/mineros/
/etc/

then installed debian on a external pi, with other SD card.
Unzipped the backup tar on the debian FS,
and debugged all day to get the dependencies right.

For convienence I have made a shell script for doing it at once.

as You can see it will first update all dependencies,
then compile cgminer and link it all.
Afterwards 2 things still need to be done:

-auto start mineros.
for this is the backup tar of /etc needed, because of all the symlinks being used,
for ex. /etc/rc0.d/K99boot.py links to /etc/init.d/boot.py,
which links to /mineros/boot.py.

Im not sure if linking it will do

##   ln -s /mineros/boot.py /etc/init.d/boot.py
##   ln -s /etc/init.d/boot.py /etc/rc1.d/K99boot.py
##   ln -s /etc/init.d/boot.py /etc/rc4.d/S99boot.py
##   ln -s /etc/init.d/boot.py /etc/rc5.d/S99boot.py
##     ln -s /etc/init.d/boot.py /etc/rc2.d/S99boot.py
##   ln -s /etc/init.d/boot.py /etc/rc3.d/S99boot.py
##   ln -s /etc/init.d/boot.py /etc/rc6.d/K99boot.py
##   ln -s /etc/init.d/boot.py /etc/rc0.d/K99boot.py

also executed:
cd /etc/init.d/
insserv boot.py
and changed the runtimelevel to 99 afterwards.

Still the boot.py in the mineros folder is NOT correct:

insserv: warning: script 'boot.py' missing LSB tags and overrides
To add an header use:
https://wiki.debian.org/LSBInitScripts

afterwards you can remove the header, otherwise python cant execute the file.

An other thing that needs configuring is WLAN (if needed)
nano /etc/networking/interfaces

auto lo
iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
        #wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
        wpa-ssid
        wpa-psk
        wpa-key-mgmt WPA-PSK
        wpa-group TKIP CCMP


NOTE the 2 lines:
        wpa-ssid
        wpa-psk



BITMINE:
1.
What I didnt get working is the front display showing the ip address of the WLAN interface.
It works for eth0, not for wlan0.
2.
If you look at cgminer's output, I see lot of underflow warnings. (not enough work)
Why?

ssh into machine
execute:
screen -DR

(with above the desk is connected through eth0, to make sure it wasnt the wlan0 causing it)
(its only during startup)


3. Memory doesnt show up anymore. It shows 0.....

hope it helps also for you guys,
have phun with it!

how much power for 272 GH ??

As long as hardware errors are below 1-2% everything is fine.

Wether you get hardware errors or not isn´t only frequency dependant, but also how much power you can supply.
Technobit Hex8A1 run really stable but also have a higher power draw when overlclocked (around 1,5W/GH). They are also cooled better.

Normaly .

BUT
Technobits HEX8A1 is based on CC A1 Chips and the Layout and Stability ist much much better.
I overclocked 8 A1 Chips (25ghs each = 200 GHS ) to 272 and NO !!!! HW Errors.

On the CCD i will assume  5-10% Power from Nominal Mode  and get 1600 HW Errors in1h or so ?

Its the Design or the Firmware . Crappy

Greetz Glen

Try the one you linked from ebay, or try buying another one of the PCIE power cables from your psu manufacturer. Isn`t the gain from overclocking these really minimal?

in turbo ligh i get around 0,66 % HW Error -> i thinks its ok...

anybody how has an solution for the problem ?
adapter from 8 pin to 6 pin ?

the problem is that i can't go higher than "turbo light" -> in each higher mode the psu shutdown after 30 - 60 minutes.... and in the extreme turbo mode the psu shutdown after 2 sec

You would expect a higher hardware error rate when chips clock higher, that is completely normal.

If the unit shuts down in high power mode, it is probably because the PSU is not providing enough energy, and it trips the PSU brakers.

After i switch to Turbo Light :

NOT GOOD !!!!!!

i search an adapter from cpu 8 pin -> to pci, but i can't find... or an other solution, bitmine don't help  

Get an Enermaxx 1350W Built in PSU

But if i go to Turbo Light in 1h is 1600 HW Errors Shown
if i on nominal Mode in 24h max 4 Errors

BTW :

If i go to Turbo Light the w1_slave ...... repeatly enomously. If i in Nominal Mode its show in 24h approx. 10-20 Warnings

lucky for you ! nice!..... thank you  for your willing to help us and hoping you can provide us the necessary informations regarding the swiss legal system when necessary..I will ask the lawer for help if neccessary..
