Title: HELP! 4 x hd 7950 + cgminer + xubuntu 12.10
Post by: papaminer on May 14, 2013, 04:54:29 PM
Code:
uncle1@uncle1-box3:~$ aticonfig --adapter=all --odgt

Adapter 0 - AMD Radeon HD 7900 Series
            Sensor 0: Temperature - 34.00 C

Adapter 1 - AMD Radeon HD 7900 Series
            Sensor 0: Temperature - 32.00 C

Adapter 2 - AMD Radeon HD 7900 Series
            Sensor 0: Temperature - 32.00 C

Adapter 3 - AMD Radeon HD 7900 Series
            Sensor 0: Temperature - 30.00 C
uncle1@uncle1-box3:~$


and when I start cgminer:

Code:
[2013-05-14 09:53:34] Started cgminer 3.1.1



 [2013-05-14 09:53:36] Probing for an alive pool

 [2013-05-14 09:53:37] Restarting the GPU from the menu will not fix this.
 [2013-05-14 09:53:37] Try restarting cgminer.
Press enter to continue:


I did a little search and found out that:
I need this: export GPU_MAX_ALLOC_PERCENT=100

but I already have this in my script:


Quote
#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/uncle1/cgminer-3.1.1-x86_64-built
./cgminer --scrypt -o stratum+tcp://blkahblahblahlbalhblah

Might you already have some cgminer processes stranded in the background?  I've seen that type of error and that was the cause for me.  Do a ps and if you see them, kill em.

You need more RAM on your system. if you can t offer more ram or if you want to try without try lower --thread-concurrency

Did you decrease TC like the error message said?

Try 8192

The post is in the wrong forum try the hardware forum not the Alt currency forum

Did you crossfire them? If so, don't. It will increase mem usage.

You should lower you TC value, or add more RAM.
