First Rig mining slow (4x7950s) (130Mh/s per)

[LivesUnderTheBridge]

I had the same problem yesterday trying to setup 2x 7950's - exact same issue as Vuxil. One was mining half the hash rate, the other was running locked at 300 / 150 on Xubuntu 12.04.

I gave up and switched to Windows, and now I'm doing 530 KH/s per card with CGminer - and can push almost 600 KH/s, but it puts out too much heat for my fans to keep up with. I wish I could get it working on Xubuntu, but it's just not happening. Sigh.

If you guys have any luck, I'll be watching this thread.

Got any hints as to what you had tried, so we're not double working what you've already done?

What version of Catalyst were you running?
Kernel version?
Tried locking the kernel on install so it doesn't upgrade?

Also, have you tried an external fan? I got one for $15 at walmart and mine went from overheat till it shut down (100C) idle to 70C at full load.

You guys have done more than I did with it. I got frustrated much faster, and swapped to Windows. I didn't do any custom installs of specific drivers, just the latest. So I'm afraid I have nothing new to add

I was going to pickup a small fan. I think I need to do that now so I can run it harder. How big of a fan did you get? Small 12"? Or a big box fan blowing over the cards?

[LivesUnderTheBridge]

Just a 12" I think. Less than knee height off the floor, just make sure it blows good.

Sorry if this also fits into the category of "things checked long ago," but could you post your xorg.conf?

[crazyates]

./cgminer -k diablo -v 1 -w 256 -I 7 (Diablo Kernel, worksize 256, Vectors 1, Intensity 7)

This might sound stupid, but try adding a variable for all 4 of your GPUs. For example:

./cgminer -k diablo,diablo,diablo,diablo -v 1,1,1,1 -w 256,256,256,256 -I 7,7,7,7 --gpu-mediff -150

I've tried this and it doesn't work either. Thanks for the suggestion though, it was worth trying.

I played around with Xubuntu some more last night (again, everything runs fine on Windows, but I prefer Linux), and still no luck. I'm surprised there are more than just a few having this issue, and no one's resolved it yet. The only thing left to try is a different, non-Ubuntu (or Debian-based) Linux distro, as that would help us tell if it's either just some bad packages or if it's the Linux drivers themselves.

[wazoo42]

I have 3 gentoo boxes running 2x7950, 2x5830, and 1x5770/1x7950 with minimal problems in the setup if you're looking for a different distro.

Got a step-by-step guide we can follow?

11.04 was a wash. I installed Catalyst 12.8, although I only had instructions for 13.1 (seemed to be fairly straight forward, unzip, sh ./*.run, dpkg -i *.deb). On reboot it launched to X but the screen was flickering on and off with colored bars.

I'm going to dig up a gentoo iso and load it up.

[Vuxil]

I think Open SUSE would be a good next try, it's very GUI driven, so the installation process would be similar to Ubuntu. Note that apt-get will not work in SUSE, but it has it's own package management and repository system.

I'm giving up on Xubuntu, it seems to not be the answer.

Gentoo is more for relatively experienced users, and same with Arch. By advanced, I mean there's more manual work in the terminal.

[wazoo42]

What happens if you switch around the pci ids in xorg.conf, say to make 6:0:0 correspond to Device[0]-0? You can get the order linux believes the cards are in using,

Code:

cat /proc/ati/?/interrupt_info

I installed from stage 3, so after I got kde emerged all I had left to do was the following (I omitted the aticonfig step b/c I copied the xorg.conf over from my 5830 box).

Code:

emerge ati-drivers cgminer      (this pulls in opencl and amd-adl-sdk)
eselect opencl set X       (where X is the # corresponding to ati)
aticonfig --adapter=all --initial

Here's my xorg.conf, though I don't see any huge differences between ours.

Manual doesn't scare me, but it looks like installing is a bitch. I tried Xubuntu, but the installer wouldn't format my USB. Probably going to try and do the kernel lock tomorrow morning.

I'll try it in the morning, I'm exhausted.

And it formatted this morning, weird. Trying Xubuntu w/ kernel lock.

[LivesUnderTheBridge]

./cgminer -k diablo,diablo,diablo,diablo -v 1,1,1,1 -w 256,256,256,256 -I 7,7,7,7 --gpu-mediff -150

Did everything but --gpu-mediff -150. cgminer said it was an invalid flag.

Code:

cat /proc/ati/?/interrupt_info

gives me

Code:

Device: PCI:5:0:0
Kernel: 0
AsyncIO: 0
Device: PCI:6:0:0
Kernel: 0
AsyncIO: 0
Device: PCI:3:0:0
Kernel: 597359

AsyncIO: 0

Cgminer runs about the same. 530Mh/s, says it dropping threads from all GPUs but 'aticonfig --adapter=all -odgc' now says adapter 2 is running full bore.

I left dynamic intensity on (just launched ./cgminer with no flags) and GPU 0 would run up intensity. Also, only changing GPU 0's intensity effected my hash rate.

On a side note, I had to plug my HDMI into the 4th card to get video, with the other 3 displaying only a white screen.

[LivesUnderTheBridge]

I played around with Xubuntu some more last night (again, everything runs fine on Windows, but I prefer Linux), and still no luck.

What happened with it? What version of driver did you install?

I just did a kernel lock (http://askubuntu.com/questions/178324/how-to-skip-kernel-update) to 3.2.0.37.45 (had to use pico instead of gedit, as it looks like gedit doesn't load with a standard install). When looking at the "additional drivers" app (little card looking thing by the clock) the beta drivers are listed as 12.11 which makes me think that the proprietary drivers are 12.10.

Going to try the built in installer, then the hard way if that doesn't work.

[c789]

For this common problem, it seems that the issue is related to Xubuntu/Linux since many of the same people have run Guiminer on Windows and were able to obtain their expected hash rate for each card.

Maybe running Guiminer in Wine in Xubuntu would work? I just thought of this and won't have time to try it until tomorrow afternoon. I just thought I'd post the idea in case anyone wants to try before I am able to.

[wazoo42]

Looking at your output from the interrupt info, the fact that your "kernel" category is 0 for 3 out of 4 cards is telling. If nothing else, this provides a quick test to make sure the kernel and drivers recognize that all of the cards are present and operational.

[LivesUnderTheBridge]

Looks like I'm switching to windows. I've tried a few more times on 12.04 and 11.04 x64 with no luck.

[wazoo42]

Crud, I just ran into this on gentoo after updating my system. Fortunately aticonfig --adapter=all -f --initial brought it back to life.

EDIT: I put a dummy dvi plug on the 2nd card while running these commands and booting the first time.

can you pull the dummy plug, restart cgminer and see if both cards work? it would be nice to know if it's only on set that it needs the dummy plug, or always.
