Warning: I do not take any responsibilities for any and all damages caused by running this program, including turning GPUs into paper weights.

Current version: http://www.mediafire.com/?p8dxf28j9qnorza

Run it from command line:

The GPU number argument must be the first argument if you're tweaking clocks/voltage, but core/memory/vddc arguments don't have to be there.
VDDC is automatically set to the voltage of the last performance state (the 3D one), if that argument is not present.

I have only tested it on my 5850s.

nice work dude

Hi! Great work! Testing it now. I hope you could integrate it with your GUI Frontend and have like sliders or even just boxes to apply clock settings.  :)

Can't get it to work on 6950. It can get values but exits -1 when trying to set.
Will definitely donate if you will fix it.

I know it's a bit asking much, but fan control would be great! Working well, tested on a 6850.  :) And a way to reset maybe? (command) Your tools will be perfect once integrated to your GUI.

Maybe if I ever bother to switch to tabbed interface, I'll add it.

That was easy. Fan control and reset to default added. Didn't really bother testing them rigorously. Ran it once and those commands did what they are supposed to do.

I think it may be related to driver problem. Afterburner can't change RAM frequency. It remains 1250 in monitoring graphs after I decrease it in AB and apply. Not the latest driver nor Catalyst 10.2 works for me. Maybe it's because of 3*6950(unlocked) present in my system

Error looks like this:

I found that I can set memory freq, fan speed but have problems setting core and vddc. Removed afterburner and CCC

I found it was rejecting changes because of CCC overclocking limits. Have to apply this  (http://www.overclock.net/attachments/ati-drivers-overclocking-software/197671d1298832618-no-voltage-control-1st-card-only-oc.reg.txt)patch to fix things out

Where is the source?

This is very clearly a derivative of AMDOverdriveCtrl which is licensed under the GPLv2.

It very clearly is not, if you bothered to download it. Would you be willing to bet 100 BTC?
Tell me, have you ever heard of ADL? If not, may I kindly suggest that you exit the thread?

lvlrdka22, can you show how to use vddc option? Can't figure out.
Finaly program works for me very well after unlocking CCC limits

Does it set the cloks permanently, so i could set them in Windows but remove HD and mine in Linux?

Reference model? If not, probably won't work through this/ADL.

Look up RBE and BIOS modding/flashing.

Yes, Reference. Just an example of syntax plz.

I hope you realized that at stock, VDDC was 1.1 V. You were trying to set it to 1150 V.
The setting VDDC to xx MHz is just a text bug.

vddc=1.1 is an invalid argument, skipping.

P.S. it works for vddc=1 but how to switch it back?!? :)))

Found it. You try to cast parameter from vddc which is 1.1 to number. Then you multiply it by 1000. Better set in mV instead ov V and remove *1000.
So I will set voltage to 1100mV instead of 1.1V

There. I actually checked the damn thing now to make sure it works. Sorry, forgot that stringisdigit only checks for whole numbers.

Hi,

thanks for your great tool, this is just what I need.
However, I have the problem that on my HD 5830 (Sapphire xtreme) I cannot change core speed and vddc:

I can change the fan speed. Do you have any idea what is going wrong?

I own a VTX3D 6950 (non reference). VGA Bios is the same as Powercolor and Club3D non reference 6950's. Being not reference means it probably won't work or there is a hope?

Do you have any idea why the tool "changes" parameters but only fan and core really changes.
When I test with just barelyclocked.exe it prints correct changed parameters even voltage and memory. Fan is obvious (sound) and core change is verified with Mhps speed, temp and GPUz. But even it prints changed parameters in all 3 states, VDDC and memory in fact stays the same (verified with heat and GPUz).

In fact I have a problem with memory clock. Only Afterburner changes memory at all, Trixx cannot change memory clock at all. Even Afterburner cannot stick with memory settings and after reboot I have to manually change mem clock in (infamous) 4 step :) Apply OC on startup option doesn't help.

BTW: When it could just change memory clock (downclock) it would be a very useful tool to me (probably not just me :) )
Thanks in advance!

Can this tool change voltage on Sapphire 5850 Xtreme card? So far what I found only one was able to do it - Sapphire TRIXX.

über is German for over. Overclocking translates to Übertakten.
So IMO 'über overclocking' is 'double doppeltgemoppelt'.

I very much like your work though, and don't take me seriously.

I don't want it to change all of them, can I change all three separately? Or just the last one?

Is there a way to allow barelyclocked to clock above the BIOS settings, like Afterburner does? I can overclock my Sapphire 5830s to 925 Mhz with Afterburner, but get an error with anything above 875 Mhz with barelyclocked.

Can I get a copy of your NomadMemory.au3 include file?

Awesome software, much better than trixx or afterburner.
