ATI Overclocking Utility

[sabby]

Hi there,
I was just wondering if you had the source. (Easier to create a .deb)

Thank you !

As I was saying earlier in the thread I would make the source public when the ADL SDK license is changed to allow it. I believe it is a change that is already underway.

The maximum value is taken from the API which I believe takes it from the card's bios. What does aticonfig report as the max value that can be set at? Did you mean that 775 was the max stable value you could reach on linux or just the max value the app will let you set?

What he means is that ATI Overdrive says that the card can't be overclocked to more than 775 MHz. However, if you use MSI Afterburner under Windows you can bypass this limit by setting EnableUnofficialOverclocking = 1 in the cfg file and then set the MHz to whatever you like. It would be really nice if this was possible under Linux as well.

Hi there sabby.
I would like to suggest a small change for your tool.
I'm using it now with autostart and "Reload OverDrive settings on startup" to get the frequencies set automatically at startup.
However it would be nice if the program would start already minimized to the panel without the need to close the window after every startup.
Its just a small change and if you could add it in your next release that would be nice.
Thanks again.

Yes will try to add it next time, I have more free time nowadays but was waiting for the new PowerTune for the 6xxx series feature to show up in the SDK and add that at the same time...

I guess you mean this one:

Tried it but got the same result as with your tool.
Also tried aticonfig, but it gives me just the following error and quits.

alex@alex-desktop:~$ aticonfig --adapter=0 --od-setclocks=250,400
ERROR - Set clocks failed for Adapter 0 - ATI Radeon HD 4800 Series         
        Please check that input values were valid
alex@alex-desktop:~$

I guess that there is no way to get lower without reflashing, so I think I'll just stick with what I got and thats it. Well, with anything on min. I already save up to 25watts. And the temp is also falling from 80?C down to 57?C. Doesn't sound to bad.

Anyway thanks for your quick reply.

Hi sabby.

At first I want to say a big thanks for this tiny but very helpful tool.
I'm using v1.0.5 to underclock my HD 4870 on my Ubuntu 10.04 32bit pc, which works flawlessly with the catalyst drivers (release 10-12).
I set the card always to the lowest values given by the tool. In my case (GPU:250Mhz Memory:450Mhz Voltage:1237mV).
After reading the entire post it seems like some people can go even lower. (about 200/200/1083)
I also would like to go lower if its possible.
But as far as I understand your tool uses the min/max settings given by the bios of the card.
Is there a way to bypass them and set lower values than the min-settings?
Or does it require reflashing my bios with lower min-settings to be able to go lower?

Yes it depends on the bios, however I am not sure if it is possible that a card accepts a value outside its limit, my card didn't accept any value outside its reported range. I saw someone else on the forum who made a similar app you might want to give it a try perhaps his allows trying value outside the range, you can also try the aticonfig utility to see if your card will accept at least some core/memory setting outside its range. Otherwise, you would have to reflash. Not too sure it would be worth it for the few extra watt you might save over your current setting...

Okay I see, thank you for your reply.

I'm going to read the licence and see if there isn't any problem to do a package for our community.
I'll let you know.

Thank you
