Had a look at Cgminer from JakeTri and in Read ME file I can't see any voltage settings Sad

Here is copy and paste with relevant information from ASIC-README file from https://github.com/jaketri/cgminer

Code:

--hfa-options Set hashfast options name:clock@voltage0@voltage1@voltage2@voltage3:clk0:clk1:clk2:clk3

This command allows you to set options for each discrete hashfast device by
its name (if the firmware has naming support, i.e. version 0.3+). Currently
this takes as option the clock speed, 4 voltages and 4 clock offsets (voltage and
clock offset for each of the 4 cores of the ASIC)
e.g.:
--hfa-options "rabbit:650,turtle:550@800,bee:950@905@925@975@985:-100:-50:0:25"

Would set a device named rabbit to clock speed 650 MHz using default voltage, the
one named turtle to 550 MHz using a voltage of 800 mV for all cores and the one
named bee is set with different clock and voltage for each ASIC core as following:
> core 0 at 850 MHz (950 MHZ base clock with -100 MHz clock offset) and voltage of 905mV
> core 1 at 900 MHz (950 MHZ base clock with -50 MHz clock offset) and voltage of 925mV
> core 2 at 950 MHz (950 MHZ base clock with 0 MHz clock offset) and voltage of 975mV
> core 3 at 975 MHz (950 MHZ base clock with 25 MHz clock offset) and voltage of 985mV
Starting the device at a speed where it is most stable will give more reliable
hashrates long term and prevent it interacting with other devices, rather than
depending on the clockdown feature in cgminer.

Note: Setting voltage may cause a board reset and hotplug event on cgminer startup.

Many thanks

I didn't look at that file Sad

Unfortunately it doesn't work Sad

No surprise

Folder does not contain cgminer.exe file and when I insert this:

cgminer.exe --usb HFA:1 --hfa-name HFA3 -o eu-stratum.btcguild.com:3333 -u -p 123 -o

stratum+tcp://stratum.d7.lt:3333 -u -p 12345 --hfa-fan 100 --hfa-temp-target 0 --hfa-

temp-overheat 104 --hfa-fail-drop 0 --hfa-options HFA3:537@860 --api-listen --api-port 4030

just black screen flashes and that's it Sad

What I'm doing wrong ?
Did I download wrong file ?
Should I copy cgminer.exe from normal cgminer folder ?

Thank you very much for your help

Update

I have copied cgminer.exe from cgminer 4.3.4 folder and I'm getting error lib.dll Cry

If you really need / want to play with voltage settings then keep in mind that you need to set the voltage only once because voltage settings are stored in flash storage on the board.

To adjust voltage settings for Habanero board you can use either HFTool ( https://bitcointalk.org/index.php?topic=639810.0 ) or my cgminer fork.
Each solution have it's own challenges ...
- HFTtool need python with pip and pyusb support.
- cgminer fork need to be compiled from sources.

For Linux users both solution are relatively easy to use.
For windows users each solution have it's own challenges ... For HFTool it is not easy to setup a Windows system with python + pip + pyusb (I did not see any confirmation of windows system working with HFTool). For cgminer you need to know how to use a C compiler .... if you have one ...

I guess it may be possible to use a Linux LiveCD and install pip & pyusb to be able to run once HFTool and setup the voltage.

Unfortunately I cannot run any tests because I sold all my Habanero boards.

Jake,

thank you very much for your help

When I was buying hab board I have assumed that it will come in standard form(voltage) Cry

I guess I will have to pay for my mistake Cry

Fork, compile from sources Cry

I have no clue what these things are Cry

Thank you again for your help

I think there's a precompiled Windows version of that cgminer kicking around, I'll try to search for it.
Stock voltage is 945mV for when you do set it, BTW

MrTeal,

you are a gentleman

Thank you very much for your help
