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

I should be getting some eruptors next week. Are you saying with 3.2.1, I don't
need any special USB drivers or settings? I know things are constantly in flux
with these new devices...

thanks

On linux, nothing to do, just plug them in and run 3.2.1

On windows, you need to install the WinUSB driver with Zadig, not the default windows driver, then run 3.2.1

What do you think about using the VCP driver mentioned here: (works with 3.1.1)

...
Though I will add, anyone who has a few of them and uses them could they report how it's going?
Thanks.

I only have one, but it is working fine with 3.2.1 on linux.  Showing up as AMU 0 and hashing normally.  The very first time I launched 3.2.1, it didn't show up right away and then appeared 10 seconds later as a hotplug device even though it had been plugged in all along.  I assume this was just from the delay in the device getting fully initialized.  If I quit and restart cgminer, it appears right away from then on.

So, no problems yet (and I don't have the SICK problem reported by Dunkelheit667).

That is using the now-defunct serial interface which cgminer 3.2+ no longer uses, much like the ftdi_sio driver did. We use direct USB code.

Thanks, and no one is reporting issues running the normal usb devices(keyboard, mouse, printers, etc.) using the zadig driver? Planning on running them on my main desktop, so I don't want any problems with normal activities.  :-D

Zadig is a tool to associate your choice of driver with the device you want, it is not a driver. Only associate WinUSB with the mining device and don't touch any other USB devices...

hey guys

I have 3 gpus in my system 1 apu and 2 dedicated gpus, how can i startup cgminer with the third gpu (gpu 2) turned off? I tried setting intensity to 0 but that doesn't work.

Do I specify it via the -d switch? If so what is the syntax?

Thanks

-d 0-1 --remove-disabled

I added that to my bat file and i get "invalid device number"

fyi:
GPU 0 = 6950
GPU 1 = 5770
GPU 2 = APU

Thanks for your help

What is the output of 'cgminer -n' ?

First of all, thank you for taking care!

And here you go. Good news, my AMUs were detected on the rpi. Bad news, declared sick after 60 seconds hashing:

I'm experiencing a issue with CGminer.

I recently moved my XFX 6870 from my gaming machine which was used to mine when I wasn't gaming to my first rig.  I keep getting error's from windows saying it had to stop the program from running.

MoBo: msi x58A-GD45
Proc: I7 920
Memory : 2GB
Video Card: 6870 XFX HD - CCC Version - 13.4 Direct3D Version 9.14.10.0969

Not entirely sure what the problem could be.  I've tried running as admin.  Any help?  Thanks!

I had same problem with incompatible OpenCL driver combination... Changing it might help

In event log, I'm getting this error -

Any help on this.  Google is saying that some of these error's happen when the Proc trys to access "No-Mans Land" in the memory.  It's pretty much a dump spot.  Any advice?

Same issue with Ubintu. downgraded to 3.1.1 again.

[Lucko]

This happened when I added 5970 and 5770 to my miner. With only 5 cores I didn't have problems. But I do have a mix of cards if that might be a problem. 6790, 6870, 5850, 2x5970, 5770. Running 2.11.4, but the same problem is on 3.2.0(3.x has problems with my pool. I get disconnected all the time).

You've been told not to use -I 9 or higher for sha256 mining like 3 times now.  Don't do it.  When you decide to scrypt mine, which you seemed to imply you would at some point, you can try again, the -I levels are totally different for scrypt.

-I 9 is included in "-I 9 or higher".  Run at -I 8.  None of the cards in your original quote start with a 7 and I'm pretty sure there has been much discussion (again, 2 or 3 hundred pages ago [and again, this may be an especially on Windows situation]) about -I 9 or higher only being useful for 7xxx cards.  Running at too high of an intensity will cause the cards to go slower, which is what you are experiencing.  I don't know how to test the bus, but I don't think you need to worry about testing the bus.  If you were running at higher than -I 8 before, and nothing changed but an additional card on the bus, that seems like a pretty good test/indicator that the bus is overloaded.  If anything else changed at the same time, then you can troubleshoot what else changed by trying to change it back and/or starting from scratch.  If you were running a higher intensity on a different program before, then the numbers don't necessarily mean the same thing on a different program.

Whatever... I figure it out but I don't know why this works... I have changed difficulty from 2 to 8 and now I can set intensity to whatever I like. And I got back missing 150MH by seting cards to 10 and 12. So I'm on full speed now. I know it is not the internet since I have tested the cards on another computer before installing it and they worked... I still think it is a bug...

EDIT: So that much about getting slower over 8...

[Naelr]

I am running Ubuntu 12.04 LTS.... Have 1 GPU, 1 BFL single fpga and 8 Block Erupters plugged into this machine.

Using cgminer 64 bit 3.2.1 the block erupters keep going zombie, after about an hour I have 21 zombies.. the good thing is they keep getting reset and keep right on hashing... but this can't be a good thing.... Kano, should I get and try your patch 3.2.1a?  can I help add some more info....

The BLF and the GPU are fine and stable.

Is there any performance benefits to 3.2.1 over 3.1.1? yeah, i know ya changed how the drivers work, but i'm wondering if i really need to upgrade a dedicated rig with ASICminers and one small GPU since i currently have 3.1.1 working. I'm kind of thinking "if it ain't broke, doen't fix it.".

It spouse to be less HW errors and CPU usage... So yes... More shares and less power consumption...

Ok, thanks. i'm not seeing many hardware errors, maybe 1 per 15 minutes, if that.

Sounds like the CPU (or 100% CPU utilization AMD driver bug) is your bottleneck and not the bus.  If you have a dual core or hyperthreading, 50% CPU = 100% CPU Utilization because cgminer is single-threaded.  I apologize if that last (italicized) statement isn't true, because I don't know it to be fact from reviewing any code.  To clarify, I haven't run cgminer in Windows in a long time, but when I did, it seemed to be the case (it might be something else related to the drivers that is single threaded).  Regardless, the point is that by increasing the difficulty, you reduced the number of shares that cgminer had to use the processor to validate, allowing more processor time to generate and distribute work.  That having been said, if cgminer is still using 50% CPU, that is still wasting a lot of electricity and may not be worth the additional 150MH/s and/or the additional variance the higher difficulty will bring.

Nope one core. AMD 145... 35W on full and less then 50% usage... Pool is DMG so variance is not big issue. I got it working. I don't know why but it works. And I will not fix it until it brakes again...

Well I'm still using 2.11.4 since there is something in 3.x that makes it disconnect from my pool every now and then... So I'm also a fan of don't fix it if it is not broken... Hire uptime is important...

[fcmatt]

This is a very long thread and my google searches have not discovered anything.

My question is has anyone seen cgminer fail to update the "Block" it is working on even though
in the output you see that "Stratum from pool 0 has detected a new block"?

I am using 3.1.1. I am mining with --scrypt. It does not happen right away. The cgminer program
might have to be running for a week. I have seen it happen a couple of times now on different
mining computers.

I wanted to check the CHANGELOG but it appears to not contain anything.

Simply closing the program and reopening it fixes the issue.

So I am asking here. Thanks.

Ok after zombies made my console go off the screen I stoped and restarted and almost instantly AMU 8 zombied and restarted.

i used 3.2.1 but didn't recognize the usb asicminers. Perhaps because i use a usb 3.0 hub ?

Have the same problem. Followed all the steps. I'm on ubuntu 12.04.

Edit:

Never mind, It works  . However, I need to start cgminer and then restart it again in the menu, in order to detect the USB sticks.
You might want to try that. Also, check if cgminer detects the USB miners without the hub. If so, the problem is probably in the hub.
