CGMiner Freezing - Ubuntu

[tagged]

Hello all!

I got my second mining rig built and can get 3 7950s running. After a random amount of time CGMiner freezes. Below is a list of things that I have tried and cannot get it to stop doing it. Looking for advice to see what the problem could be.

Here is what I have tried:
Powered Risers, non powered risers.
Each of the 3 cards individually, one card took about 3 hours, other combos usually was 10 to 60 minutes.
Heat is not an issue, no cards get above 74.
Tried mining one card from different PCIe slots, using different risers.
Reinstalled different versions of CGMiner (3.1.1, 3.2.0, and 2.11.4).
Tried mining inside of byobu and directly in putty.

The whole system does not freeze. I can kill putty, restart it and log in again. If i try to run Cgminer again it hangs on the first screen that says the CGMiner version.

Only thing different on this system is that I installed a Minecraft server.

Not had this type of problem, and only a tad familiar with Linux. Not sure if there are any logs I can check on, or what other information anyone may need to help isolate the issue.

Thank you all for being such a great community!


(I am running scrypt and mining altcoins mostly)

Can you post your conf file?
Are you getting any HW errors or high stale rates?
What kind of power supply are you using?

Not getting any hardware errors. Getting some rejects but when mining one pool it is like .03% so not bad.


Config file I think you are asking for?:
#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/rig2/cgminer-3.2.0-x86_64-built
./cgminer --scrypt -I 17 -g 1 -w 256 --thread-concurrency 21712 --gpu-engine 1025 --gpu-memclock 1450 --gpu-vddc 1.087 --temp-target 77 --auto-fan -o stratum+tcp://dgc.epools.org:3338 -u [username] -p [password]


With the intensity down to 17, engine down to low 10xx, and memory in low 14xx it lasts a lot longer. When i run this rig at I 20, E 1050+, M 1500 it freezes pretty quick, with any combo of cards or card.

If there is a different conf you are looking for let me know which and i will copy/paste it here.

Thanks for your help!

Are you sure youre clock settings are stable, why not try o run with lower OC (or stock) for a while.
I usually find myself using unstable clocks even tho I thought they were stable

Are you using dummy plugs? Also try upping your voltage maybe 1.15

What version of linux do you use? Especially what version of X server and fglrfx?

I had similar problem and i did this.

Don't know if it helps you but i will post it:

Code:

sudo su

echo "deb http://archive.ubuntu.com/ubuntu quantal main restricted universe multiverse" > /etc/apt/sources.list

apt-get update
/etc/init.d/gdm stop

apt-get install xserver-xorg

rmmod fglrx

mkdir /mnt/tmpfs
mount -osize=1024m tmpfs /mnt/tmpfs/ -t tmpfs
cd /mnt/tmpfs
wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip
unzip  amd-driver-installer-catalyst-13-4-linux-x86.x86_64.zip
sh ./amd-driver-installer-catalyst-13-4-x86.x86_64.run --force

rm /etc/X11/xorg.conf
aticonfig --initial --adapter=all

/etc/init.d/gdm start

This upgrades to  xorg-server 2:1.13.0-0ubuntu6  which seems more stable than xorg-server 2:1.10.1-1ubuntu1

Check this:

Code:

grep xorg-server  /var/log/Xorg.0.log

to know what version of X org you running

Cheers

 grep xorg-server  /var/log/Xorg.0.log
[    17.925] xorg-server 2:1.13.0-0ubuntu6.2 (For technical support please see http://www.ubuntu.com/support)

Looks like I have 2:1.13.0-0ubuntu6.2... 

Will try mining without any OCing and see what i may

I am using dummy plugs. Voltage setting actually has not ever actually changed anything, i have read that is a linux limitation, but will try adjusting in case 1 card is taking it and i just didnt notice.

Thanks all for the ideas
