I did exactly what ckolivas suggested in that post.. Cgminer defaulted to tc 22400, but that was a lot slower than 8192, so I manually set 8192.
1880 MHz turned out to be maximum stable memory clock and I went through 900 - 1175 MHz GPU in 5 MHz increments and at 1175 MHz GPU I finally reached 600 kh/s.

Dunno what else to do at this point.. Does anyone have any ideas? I wonder which driver set is ckolivas using?

I'm using Catalyst 13.3 beta3 || cgminer version 2.11.3
Code:
--intensity 13 --worksize 256 -g 1 --thread-concurrency 8192

Some results that I wrote down:

EDIT: However...
Code:
proofer@prooferminer:~/miners/cgminer$ DISPLAY=:0 fglrxinfo
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  19 (X_GLXQueryServerString)
  Serial number of failed request:  12
  Current serial number in output stream:  12

SOLVED  Smiley

Problem summary: Upgraded Ubuntu to 12.04; found that AMD Catalyst 11.12 driver (a.k.a. fglrx 8.92) is incompatible with Xorg X server 1.13.0, which is in 12.04.2, which is the current release of 12.04 LTS (Precise Pangolin). There was also an issue of 12.04.2 having kernel 3.5, which is  incompatible with Catalyst 11.12's installer; it wants kernel 3.2.

Solution: install 12.04.1, which has xserver 1.11.3 and kernel 3.2.  Even after running Software Updater, which updates to 12.04.2, xserver stays at 1.11.3 and the kernel stays at 3.2. 12.04.1 is available here.

*headache* So is all this new stuff just for 7970's? Or would a 7950 suffice...
Im running 2.10.4 right now and im wondering if i'll notice any benefit to upgrading all my miners (some use 5xxx 6xxx) or if just my 7950 will benefit.
Would a 7950 show a hashrate increase if i was to update to 2.11.3?

Try varying your intensity, both up and down.

My 7850 does 360kh/s at 13, and 390 kh/s at 12, all else equal (g 2, 13k threads). I can also get to 390kh/s with I 19, g 1, 26k threads, but that makes my desktop unusable.

What I did in order to find the optimal thread concurrences was to keep an eye on the amount of memory my card was using with each setting (with gpu z). If there was free memory, there was room for more threads.

Just make another directory, put new mniner into it, copy config files, run and see...

I wonder which driver set is ckolivas using?

I'm using Catalyst 13.3 beta3 || cgminer version 2.11.3
Code:
--intensity 13 --worksize 256 -g 1 --thread-concurrency 8192
I use the very first driver that supported the 7970, aka 11.12 with 7970 hotfix:
amd-driver-installer-8.921-x86.x86_64.run
I also use SDK 2.7 which seemed the best.

And as I said, I went by increments of 1 to the highest engine clock at that stability and intensity of 20 for a final:
Code:
--scrypt -I 20 --gpu-engine 1157 --gpu-memclock 1900
Which gave 725kH without setting shaders, lookup gap, or thread concurrency.

Once again, your mileage may vary since all hardware is different, more system ram might help etc. Note also that setting the CPU frequency to performance instead of ondemand also helped a little.

Is there a way to mine on Linux without running X?  It seems like running a grpahical display cuts around 100kH/sec off your speed on the main card.

No. Only Nvidia drivers are smart enough to do that.

It shouldn't. You are probably using a compositing window manager and/or some graphical applications using the GPU. If you are using a desktop environment, try to run the simplest window manager you can (twm or fvwm) with no widget. Run your mining program in screen or tmux to avoid any X terminal.

Edit: I don't see any speed difference between the main card and others on my rigs. They all use the standard Xubuntu desktop.

Thanks for the tips. I'll give it another try tomorrow. Intensity 14+ is not working at all (kills performance), so I'm hoping it's a driver issue.

You know that's what happened with earlier versions... are you sure you're on the latest cgminer!?

not working.

2.10.5 works perfectly.

May be I should modify/change something on my config file.

      "url" : "xxxxxxxxxxxxxx",
      "user" : "xxxxxxxxxxx",
      "pass" : "xxxxxxxxxxxxxxxx"
   },

   }
],

"api-port" : "4028",
"disable-gpu" : true,
"scan-serial" : [ "bitforce:COM3", "bitforce:COM4", "bitforce:COM5", "bitforce:COM6", "bitforce:COM7" ],

Any help would be appreciated.

Try NOT ignoring the big fat warning at startup that says you need to install a new driver?

Thanks.
But the warning/message run so fast I can read it and dont know how to pause it.
Where can I get the new driver?  I'm running BFL FGPA Single.

You need to run terminal from command line, so it does not close on you.

windows (shift + right click) open command window here

you need to change your driver with zadig to the new driver.

Best drivers for 5000 series were 11.6, but they won't even run on ubuntu 12.10 because of the newer Xorg.
