Yeah I'm trying to find the peak under 9 right now. Thanks for the tip and the config file. I was just using the auto-generated one. And yes the export command did work for that, however I still only can get GPU 0 to mine

Oh sorry i have intensity turned off on GPU 1 in the config so I can get an accurate reading on GPU 0's hash rate. The values I posted of the hash rate show I:14 for both GPUs

Unfortunately I've already tried using

Code:

export DISPLAY=:0

to no avail.

I start it using

Code:

screen cgminer

my config file:

Code:

{
"pools" : [
        {
                "url" : "http://mint.bitminter.com",
                "user" : "lsmith130.worker1",
                "pass" : "pass"
        }
]
,
"intensity" : "14,0",
"vectors" : "2,2",
"worksize" : "256,128",
"kernel" : "phatk,phatk",
"lookup-gap" : "0,0",
"thread-concurrency" : "0,0",
"shaders" : "0,0",
"gpu-engine" : "0-0,0-0",
"gpu-fan" : "0-100,0-100",
"gpu-memclock" : "150,150",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "0,0",
"gpu-vddc" : "0.000,0.000",
"temp-cutoff" : "95,95",
"temp-overheat" : "85,85",
"temp-target" : "75,75",

"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

and --odgc output:

Code:

Adapter 0 - ATI Radeon HD 5900 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    725           150
             Current Peak :    725           150
  Configurable Peak Range : [550-1000]     [150-1500]
                 GPU load :    99%

Adapter 1 - ATI Radeon HD 5900 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           150
             Current Peak :    725           150
  Configurable Peak Range : [550-1000]     [150-1500]
                 GPU load :    0%

Here is the displayed hash rate in cgminer

Code:

GPU 0:  51.0C 4551RPM | 166.3M/172.1Mh/s | A:15 R:0 HW:0 U:2.00/m I:14
 GPU 1:  34.0C 4545RPM | 199.2M/148.2Mh/s | A:14 R:0 HW:0 U:1.87/m I:14

These numbers always add to the expected hash rate for GPU 0 only.

After using aticonfig to overclock the --odgc reports:

Code:

Adapter 0 - ATI Radeon HD 5900 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    750           150
             Current Peak :    750           150
  Configurable Peak Range : [550-1000]     [150-1500]
                 GPU load :    99%

Adapter 1 - ATI Radeon HD 5900 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           150
             Current Peak :    770           1050
  Configurable Peak Range : [550-1000]     [150-1500]
                 GPU load :    0%

I'm completely stuck. Somehow cgminer is convinced that two of the threads are running on GPU 1 when really all four are on GPU 0.

Ok I've almost got everything working. My last problem is that both GPUs are detected and it says they both are hashing at about half of normal rate, but the activity on the second GPU is 0% and the clock is running at idle speeds. if I set the intensity on the second GPU to 0 then it reports that GPU 0 is hashing at normal rate and GPU 1 is barely hashing. I tried using the --gpu-map option to swap the GPUs, and the hardware reports are switched appropriately but the (already incorrect) hash rate reports are unchanged. If I could at least choose which GPU to run then I could run two instances of CGMiner, one for each GPU.

Ahhh it gave me an error telling me I forgot to rerun Code: sudo aticonfig -f --initial --adapter=all when I reinstalled. I've got a different error now but I think I can handle it from here. Thanks so much!

Other / Beginners & Help / CGMiner on Ubuntu Hangs on Startup

on: November 08, 2012, 12:49:14 AM

I've been going at this for two days now. When I start CGMiner it clears the screen and says Code: [2012-11-07 19:43:35] Started cgminer 2.9.1 and just sits like that. If I run it with the flags that don't launch it fully, like --help, it works fine, except with -n, which causes it to hang too. I've tried everything I can think of, including running as root and uninstalling and reinstalling the drivers and even Ubuntu from scratch. Any help would be very much appreciated. -- Edit Oh and my rig has one 5970 and is running Ubuntu 12.10

Other / Beginners & Help / Re: ASIC Mining Soon to Be Unprofitable??!?!

on: October 04, 2012, 10:48:05 PM

It's very unlikely that the hashing power will end up in just a few hands. After the switch to ASICs there won't be any more foreseeable major jumps in hashing rate, and if anyone were to get anywhere near a 51% attack then everyone would bail out of bitcoin, making it worthless. There's no incentive to get that much hashing power. Also, because ASICs make hashing power so cheap and low power, there will be a low barrier to entry of the market for a very long time, allowing the power to distribute more evenly.
