Anyone knows how to overclock these on Linux? I have ATI Catalyst on Ubuntu, but it's missing the overdrive section that windoze has...

First, Then aticonfig --od-setclocks=coreclock,memclock --adapter=num
where num is 0,1,2,... or "all". Commit is for setting it permanently (it will clock at this value after restart) aticonfig --odcc --adapter=all
This command checks the clock aticonfig --odgc --adapter=all
And this one temperature: aticonfig --odgt --adapter=all
The list of these commands is avalable by To set the fan at 70% aticonfig --pplib-cmd "set fanspeed 0 70"
If you have multicard display, you need to set export DISPLAY=:0.num, where num is GPU num before submiiting the set fanspeed command.

Can you please share your best OC settings, when you find them ?

Best OC settings vary greatly. For 5970 it is usually around 800 MHz.

I have an HD6950 with extra shaders unlocked. odgc shows a max peak range of 840.. is there any way to push this up more? root@fry:~# aticonfig --odgc Default Adapter - AMD Radeon HD 6900 Series Core (MHz) Memory (MHz) Current Clocks : 810 1250 Current Peak : 810 1250 Configurable Peak Range : [500-840] [1250-1325] GPU load : 99%
I set it to 840 root@fry:~# aticonfig --odsc=840,1250
Default Adapter - AMD Radeon HD 6900 Series New Core Peak : 840 New Memory Peak : 1250 root@fry:~# aticonfig --odcc Clocks persisted for the Default Adapter - AMD Radeon HD 6900 Series
and get an extra 10,000khash/s but I'm curious how to push it outside this range. Seems possible in windows. Also, does anyone know how to set fanspeed back to auto? aticonfig --pplib-cmd "set fanspeed 0 auto" seems to just turn the fan off..

Guys, any idea what's the maximum temperature value that's "safe" for 5970?

Mahkul, whose 5850 card are you running and which bios? I have a Diamond 5850PE51G that won't let me go above 775 MHz using aticonfig. I tried several overclocking bioses including MSI and ASUS, but Linux won't boot with them in.

They are Sapphire. As for the Bios version I will check that for you tomorrow; the clock... I think I was able to go up to 900MHz, but will let you know for definite tomorrow. As for the 5970 it is a Sapphire as well and I was able to overclock it to 1010MHz (GPU core clock!). I must get some better cooling solution, because the temperature goes too high on them at that frequency, so I have to run them at 800MHz for now (getting 306Mhash/s each core).

is there any way to downclock my memory without flashing the BIOS? don't really bother about the clockspeed, but i'd like to lower the memclock a bit, if possible. noodles@ubuntu:~$ aticonfig --odgc --adapter=all
Adapter 0 - ATI Radeon HD 5800 Series Core (MHz) Memory (MHz) Current Clocks : 775 1125 Current Peak : 775 1125 Configurable Peak Range : [550-775] [1125-1125] GPU load : 99%
Adapter 1 - ATI Radeon HD 5800 Series Core (MHz) Memory (MHz) Current Clocks : 775 1125 Current Peak : 775 1125 Configurable Peak Range : [550-775] [1125-1125] GPU load : 99%

where num is 0,1,2,... or "all". Commit is for setting it permanently (it will clock at this value after restart) aticonfig --odcc --adapter=all
so if you want the GPU at 900MHz and the memory at 950 on all adapters, you'd do aticonfig --od-setclocks=900,950 --adapter=all

Sorry, I didn't look closely... it appears your memory isn't underclockable with your current bios. Someone else might know how to set it to something outside of the range, but I don't.

well, it is "underclockable" on windows, had it running at 800-900MHz the last week. now i finally got ubuntu setup and running, just with some more degrees on the cards cuz of the higher memclock, which...well, kinda sucks. ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

I believe what moa tried to say was that you have to use the Radeon BIOS Editor (under Windows) and flash them.

actually, i found you can use RBE tool under wine and create usb boot disk with freedos to use dos atiflash tool. no windows required.
