OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Zanatos666]

Stuck it in the fridge for about 30 minutes and it doesn't seem to have helped. If anything, it looks like it's gotten worse; down to ~5.4 GH/s now.

That doesnt sound like a particularly good idea.  Have you tried removing the casing and inverting the fan so its blowing down?

I did that a couple days ago and my temp went from 45C to 35C.

I did that when I flashed my firmware.  Even with the increased hash rate, I went from ~42 to ~38.  Just breathes better.

Did you guys keep the big 120mm fans, or get rid of them along with the case? If you got rid of them, I'd imagine just the two smaller fans would be a lot quieter than all 4.

Greetings.

I'm a recent entry into the world of ASIC mining. I've got a small array of 31 ASICMiner Block Erupters that I'm trying to set up as a "fire-and-forget" setup that I can just run in a remote location (where I get free electricity).  Eventually I plan to run this off a Raspberry Pi, but that's a story for another day.

Right now, I'm using a Windows 8 x64 PC as a host. I've consistently been getting crashes when running cgminer.  Here's my setup:

6x D-Link DUB-H7 hubs

Hub #1 is the "master" hub.  The other five connect to it.  Hub 1 also holds a USB fan and a single block erupter.
Hubs 2-5 each contain six block erupters.  Each is plugged into hub #1.
Hub #1 is connected to my host PC.

I ran the zadig tool and configured the drivers.

With cgminer 3.3.1, if I plug in the array first, then start cgminer, cgminer will instantly crash.  If I start cgminer first, then plug in the array, it seems to work.  At least, I didn't experience any crash issues.  However, this is unsustainable as I plan to run this rig remotely, so I need to be able to reboot the machine periodically without having to unplug and replug the array.

With cgminer 3.4.0, I can start it with the array plugged in, and it hashes normally, at expected values.  However, after about 1-12 hours (varies), it crashes as per the screenshot below:



In this screenshot, it crashed after only about an hour of running.

My config file only contains my pool info, no other options.  I start cgminer with a shortcut in the startup folder in windows, which just runs the executable - no command line options.  Alternately, when restarting cgminer after a crash, I double-click on the .exe.

Any thoughts on what I might be doing wrong?

I'm thinking of just using the looping-restart batch file someone posted earlier in the thread, but that's just a workaround, not a fix.

(Side note: My PC has an AMD APU, which cgminer picks up and runs for an extra 50MH/s.  Bonus! )

Hubs 2-5 each contain six block erupters.  Each is plugged into hub #1.

What is the current rating of your hub power supplies?  You need more than 3 Amps as each Erupter draws .5 Amp.

Its a single 92mm fan.  I kept it, its not bad.  Its sitting on top of my desk in an office.  I get enough of people talking around me, plus I have headphone on 99% of the time so I never hear it.

3A, 5V power supplies.  Over on the USB hub thread, these have been consistently reported as supporting 6BE each, sometimes 6 + a fan.

Yeah, I see that happen too with mine.  Sometimes they go 2 days without crashing, and some days they crash every other hour. I dont know.  I do have a crappy hub but not trying to spend money on one for the 3 I have.

I would say make sure you have some sort of fan blowing on them, even just a small USB fan.  Plus, since you are using Windows, download CGWatcher and run it.  It will watch for the crash and if so will restart them.

I do have a fan on them; I'm also debating whether to add another one or not.  The miners are distinctly warmer now since I added the last batch of 10.

Thanks for the tip about CGWatcher! It seems to be exactly what I need. =)

I do plan to eventually port my rig over to an RPi, but that can be an adventure for another day. =)

Mine has always been around 35C since I moved it down to my basement.

Hi All,

My advice would be not to mine with a nvidia GPU, as odds are it won't be profitable.
Also it seems your running a highly outdated build of CGminer, we're at 3.4.0 now..

[kano]

The error simply means that whatever bazaar OpenCL SDK he is using, it doesn't support the current cgminer *.cl code.

... and that is about the end of the story.

[Its About Sharing]

Question - is there an easy way to run a few erupters, one Jalapeno and some custom rigs (e.g., Burning Mining) off of one Raspberry Pi w/ MinePeon w/ cgminer AND be able to overclock the custom rig?

Could I just install another instance of CG Miner or can I do the overclock of a specific rig while not affecting all rigs?
Or would it be better/simpler to get another Raspberry Pi?

I am not script writing capable, so please consider that.

Very much appreciated,
IAS

I have problem on gentoo system witch new version.

First time compile I got this error:

Code:

make[2]: Wejście do katalogu `/media/tmp/cgminer'
  CC     cgminer-driver-icarus.o
In file included from driver-icarus.c:50:0:

libusb.h: Nie ma takiego pliku ani katalogu = no such file or directory

on my Gentoo I have libusb.h on directory /usr/include/libusb-1.0/libusb.h
so I added to this path to configure

Code:

./configure CPPFLAGS="-I/usr/include/libusb-1.0/"

Configure works ok, but I see new error on make:

I have compiled 3.3.1 version and it's works.
Also I have latest in gentoo libusb version 1.0.9

Any help ?

[kano]

Coz you have to put it in CFLAGS before ./configure ...

[svirus]

same problem...
There is no diffrent to put in above or before

Code:

# ./configure --help
`configure' configures cgminer 2.11.4 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.
...
Some influential environment variables:
...
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>

[kano]

Ignoring the fact that you are not using the current cgminer 3.4.0
You must also either being using some weird version of configure or typing something wrong

On Windows Mingw, Ubuntu, Xubuntu, Debian, Fedora, Mac OSX, Arch it works.
Though, the fact that your environment is not setting up libusb correctly probably doesn't help ...
Also your configure command is missing asking for any drivers ...

Bottom line, if you are going to use some non standard linux environment that doesn't work the same as all the above ones, then you'll need to work out how to set it up yourself - if on the other hand you simply aren't typing the configure command correctly, look in the README ...

The makefile won't compile the Icarus code without --enable-icarus ... so my guess is you are messing with the configure yourself and that is the problem.

Oh, no - please don't mention a different miner in this thread!  Kano will post a 10 paragraph reply accusing you of being a shill who is just advertising for that crapminer you mentioned.

A miner that adds features that CGMiner does not have is not a bad thing. A miner that copies CGMiner and then claims that CGMiner is inferior in every imaginable way is something that Kano does not seem to take lightly. See the difference?
