Title: [SOLVED] Need help to maximize the gpu usage on a 5970 with Linux Ubuntu 11.04 Post by: SicKk on May 30, 2011, 11:21:12 AM as the subject says I need help....
o.k. long story short : System : Linux Ubuntu 11.04 amd64 AMD Phenom x4 9850 Black Edition 4x2.5Ghz 2GB Ram XFX ATI Radeon HD 5970 XFX Black Edition 4GB aticonfig --odgc --odgt --adapter=all Quote Adapter 0 - ATI Radeon HD 5900 Series Core (MHz) Memory (MHz) Current Clocks : 950 300 Current Peak : 950 300 Configurable Peak Range : [550-1000] [210-1500] GPU load : 82% Adapter 1 - ATI Radeon HD 5900 Series Core (MHz) Memory (MHz) Current Clocks : 850 1200 Current Peak : 850 1200 Configurable Peak Range : [550-1000] [1000-1500] GPU load : 57% Adapter 0 - ATI Radeon HD 5900 Series Sensor 0: Temperature - 77.00 C Adapter 1 - ATI Radeon HD 5900 Series Sensor 0: Temperature - 68.00 C I've downclocked the first GPU memory to 300Mhz with AMD Overdrive Ctrl and got a good power saving. can't figure out how to downclock the second GPU. when i run a miner only on the first GPU, i get up to 415 Mhash/s with a GPU load of 99% and a core temperature 78°-82° celsius. if i run an another miner on the second GPU, well you see the result above. could soneone please give some advice how to downcloak the memory and overclock the GPU. or how i could set the second GPU to be default, and maybe be able to make the setting with AMD Overdrive Ctrl. thanks for your help in advance Title: Re: Need help to maximize the gpu usage on a 5970 with Linux Ubuntu 11.04 amd64 Post by: SicKk on May 30, 2011, 01:46:19 PM o.k. another problem, I cant disable CrossFire.
aticonfig --lscs Code: Candidate Combination: aticonfig --lsch Code: CrossFire chain for adapter 0, status: enabled aticonfig --help |grep crossfire Code: --lscc, --list-crossfire-candidates aticonfig --lsch Code: CrossFire chain for adapter 0, status: enabled aticonfig --cf=off --adapter=all Code: CrossFire chain(s) disabled aticonfig --cfd --adapter=all Code: CrossFire chain(s) disabled and after reboot the crossfire link is enabled again. does anyone has a clue why this is happening ?

I stumbled upon this thread because I've got an 11.04 rig with a 5970, but I can't seem to get both cores working efficiently. When I start the first core, I can get just over 300 M/hash, but when I start the second one, the first one drops in half. I've followed these instructions to disable crossfire, but now after I start the first device, I get this error after starting the second device: Code: Kernel error: Unusual behavior from OpenCL. Hardware problem? I tried https://bitcointalk.org/index.php?topic=14340.20 (https://bitcointalk.org/index.php?topic=14340.20) these instructions for plugging and unplugging the monitor before starting each device, but I'm still only getting about 300 M/hash, which is obviously way low for a 5970. Ideas? |
