Has anyone successfully set the GPU voltage using cgminer under linux for a R9 290(X)?
I have my gpu clock, memory, and fan settings where I want them to be but I wouldn't
mind under-volting the GPU to save a little energy and heat. I *believe* cgminer wants
an exact voltage and not a delta but I could be wrong. I don't know what the normal
voltage is for a R9 290 and every attempt to enter an absolute value like 1.25 fails (out
of boundary). Many thanks in advance!

I have been in that same situation for the last two days. I found some good clocks that provide a rather good performance boost in-terms of c/m. I have my 290X's running at 1150/1150. The core increase raised my c/m by ~400, the problem is that I am having some heating issues (80C - 85C - 90C spikes)...I'll try to figure out a way to undervolt on linux, I'll post my solution here if I find anything. If you find something please share.

At the moment I have multiple .sh files that I execute after a system reboot. One sets the fan speed to 100%, and then overclocks my GPUs, one to initialize the miner, and the last one to monitor temps.

Edit: I found this http://sourceforge.net/projects/amdovdrvctrl/?source=navbar, I'll give it a try once I get home. It was last update Dec 13 2013.

how to set the fan speed to 100%? with multiple GPU Fan speed? @ubuntu 12.04

Maybe your Xorg.conf is screwed. Run aticonfig --initial --adapter=all as root and restart the computer.

and how to set gpu fans in linux?

Can I ask what you are using a version of the LINUX it?
I am using UBUNTU DESKTOP version
Only recognizes a GPU, only 2300C / M ，with 3800C/M so long way
Will there under LINUX how to modify the GPU CLOCK, MEM CLOCK, GPU fans

I tested on Gentoo. The command line tool to modify frequencies is aticonfig, which should work after enabling AMD Overdrive (see --help). How many GPUs do you have? For one GPU I would use -t 0,0 and for two -t 0,0,1,1 etc.

I have a 6 GPUS, use-T 0,1,2,3,4,5 but only GPU 0 at work, I still do not understand how, under LINUX for GPU overclocking

R9 R290, Catalyst 13.12, Powertune +20%, GPU@1025MHz and RAM@1250MHz with Linux-v0.1.4 running -a 0, two threads per GPU and no other load. So far, no one was able to reproduce this in Windows but it should be possible because even a 280X easily hits more than 2700cpm. Still wondering because yesterday a user with 2 R9 290X reported only about 6100 cpm.

That's a missing library search path. execute the following command: export LD_LIBRARY_PATH=./:$LD_LIBRARY_PATH. After that start the miner.
EDIT: Could you use the address Pk3mHjZrW3HGmx5jMNaN1GhXT2WgXHjRCz if you wanna mine for me?

and how set GPU clock,GPU fans in linux?

why i juet 1 card work,can,t find the other cards?

yes i send to Pk3mHjZrW3HGmx5jMNaN1GhXT2WgXHjRCz

ub linux


btc@btc-desktop:~$ cd /home/desktop/pts
btc@btc-desktop:~/desktop/pts$ ./clpts PtLx9kDLTXtR1ae3u7naXLPeGjjHZ1PGoR -t 0
./clpts: error while loading shared libraries: libboost_system.so.1.55.0: cannot open shared object file: No such file or directory



what's problem about it?

R9 290 @1025Mhz 
Catalyst 13.12
memory clock @????
-a @??
HOW can be 3800c/m
why i just can be 3000c/m @1025   memory:1250 -a 1 Catalyst 13.12
