AMD Catalyst 11.11 Driver

That is the link you get by navigating from the AMD home page, but it doesn't work.  You have to change "amd" to "ati".

Any fix to the 100% CPU bug with 2+ video cards in Windows yet ? :(

Nope.  My guess is it doesn't fix it on Linux either but I am not going to try.

100% CPU bug is partially fixed on Linux now. Much better than before, still worse than pre-2.5.

CPU bug fixed on Linux for me! Running 3 GPUs with CPU idle!

I wonder if it's that hard to fix for them. Or maybe they just dont give a damn.

CPU usage bug is fixed for me on linux AND it works with xorg 11.1 as well now.

At last \o/

Thank GOD.  Now if they could just make their drivers work without any xorg.

For OpenCL work no need to even have a windowing system.  I mean anyone thing a 100K node supercomputer is going to have xorg running on each node.

If they want to get serious they need to kill dependency on x server.  Would be nice to have an ultra small command line only distro running cgminer.  A miner can dream right?

Well, considering my whole OS fits on a 4GB USB and actually requires less than 1GB for the base system, I don't really see it as an issue for your typical person who mines.

As for command line only distro (console boot) ... well there is even a dependency in the kernel for the graphics drivers.
A few years ago when all the shit about nVidia not doing what the kernel developers wanted was happening (kernel developers decided they were god and that they wanted to try to force nVidia to produce a free opensource driver instead of just a free driver i.e. kernel guys trying to be Microsoft), some kernel programmer had the stupid idea of requiring the kernel graphics driver to even boot to the console
Before this change it used a small simple VGA driver that supports pretty much every card ever created and loaded the graphics driver only when you started X
Now even the console boot requires the full graphics driver for the card - of course you don't need all of X, but there is still that driver requirement.

So i take it the 100% cpu bug is still present in windows?

Completely fixed under linux (ubuntu natty) with 4 x 5870 for me now

After upgrading to catalyst 11.11, I did the distro upgrade to oneiric 11.10.  It works fine. FYI.

Curious about windows.

Win 7 x64
2x5830
11.11

No dice.  100% cpu still here.

It would have been nice. :'(

Tell me about it...thinking about just switching over to a linux install and throwing cgminer on there.

Just noticed a problem with the startup module.  When I put the script to start cgminer to start at login(via the gui), some of the cpu cores gets pegged (125% cpu), however, simply starting the script in a terminal yields normal type cpu use.

I am fairly new in linux, but really happy with it, haven't used unix since college, what a change from SunOS. 8)

If your bios supports the pop up boot from menu, it is much easier to try out(provided you have a hard drive to install linux on). No dual boot issues, just bring up the bios menu and boot from any drive.--even usb drives.

Yeah, I followed the guide to get cgminer + xubuntu on a USB...but I failed and used a 2GB with 1 GB persistence; thinking it would be enough space.

Sadly mistaken.  Just gives me a good reason to go out and buy a 4 or 8GB :D

win7 64 bit 5850+4850 100%cpu just like before.

Yes, sadly, no solution for windows, seems to be fixed for linux though.

Ubuntu 11.10 64bits
Catalys 11.11
CGMiner 2.0.8 = 150% CPU consumption.

Falling back to Ubuntu 11.04 - Catalyst 11.6 - SDK v2.4 - CGMiner 2.0.6.

Best,
Thiago

Catalyst 11.11a performance driver

Guys, still no luck here... My CGMiner 2.0.8 running at Ubuntu 11.10 64 bits with Catalyst 11.11 consumes all of my CPU, all the 4 cores.

How do you guys are doing to use CGMiner 2.0.8 at Ubuntu 11.10?!

Thanks!
Thiago

I had this problem when auto starting cgminer from upstart. If it is the same issue you are seeing, try running cgminer interactively from a terminal, otherwise, idk. At least that would be a place to start.

Hi!

 Not starting from upstart. I'm using CLI.

 BTW, to avoid issues with starting it from upstart, just add in front of cgminer wraper script the var "DISPLAY=:0 cgminer -o http:dasdasdas...."

Best!
Thiago

I am not using the var DISPLAY=:0 inline.  But isn't the following equivalent?
I actually tried inserting an additional DISPLAY=:0 prior to the "exec gnome-terminal...", but I saw the cpu use max out when restarting with upstart.

Using the code above I get about 4% cpu usage, but when started by upstart: 200%

Anyway don't want to waste your time on my issue, the only other thing I thought could be a problem is if the export values for SDK 2.4 are pointed to the correct location, but that would be a long shot.  Something to verify.

11.12 fixed my CPU bug. :)  The flip side is I'm down like 20 Mhash/sec, unless those numbers were being incorrectly reported to begin with, but I'm happy that my CPU isn't in overdrive
 
edit, my Crossfire got enabled automatically when it installed 11.12 :(   I discovered this because Skyrim started playing really funky, and I remembered people talking about funky behavior with Crossfire.  So I disabled Crossfire, and my Mhash/sec came up a little bit (although it seemed about par w/out Crossfire, so maybe that's fixed now?  someone might do some more experimenting)
 
and the CPU bug is still fixed for me. :)

Catalyst 11.6 works for me on Weendoze XP 32 bit. I get better hash rates and lower temperatures with no 100% pinned CPU core, nor one core's worth of load spread out 50% per core over 2 cores. I saw the latter behavior with some post-11.6 driver version, I don't recall which one.

11.12 WHQL http://support.amd.com/us/kbarticles/Pages/AMDCatalystSoftwareSuiteVersion1112.aspx
12.1 Preview http://support.amd.com/us/kbarticles/Pages/Catalyst121Previewdriver.aspx

The AMD Catalyst™ 12.1 Preview includes all of the features found in AMD Catalyst™ 11.12 and also includes all of the latest optimizations found in the AMD Catalyst 11.11c performance drivers (AMD Catalyst 11.12 does not include the latest 11.11c optimizations).   It is highly recommended that all gamers use the AMD Catalyst 12.1 Preview driver.

Do not install 12.1 !

I can`t  overclock any 5780 and 6950  >:(

awesome)))

I tried updating to 11.12 on one of my quad radeon hd 5870 windows rigs and it did not fix the 100% cpu bug.
