    I already posted this in the ati tray tool forum, but since no one seems to have any clue about my problem, i guess it can be considered as a comment on how ati tray tool works for me (therefore satisfying this forum rules) .

    Here is the post:

    I have been looking for quite a while now at a lot of different places, but i guess if i can't find an answer here... it just means i m screwed

    First of all, i have a hd6970M which works fine, but gets a little too hot for me (around 95°c on furmark, with stock clocks (680/900 at 1.1V)
    that's why i decided to overclock and downvolt, because i encountered a lot of people who succeded in doing so.
    After trying a lot of things, i got to 800/1000 at 1.010V that works fine with saphire trix

    But with ATI tray tool, i can't go over 719/936 at 1.1V (but 719/936@1.01V works) without crashing. I get a red screen with black vertical lines.
    Even with CCC i can go to 710/1000 without any problems.

    So why do i crash when i overclock with ATI tray tool when it should work perfectly?


    I would like to add another post i published on the notebookcheck forum:

    Hi guys

    I tried downvolting/overclocking my 6970m, but i encountered some strange problems

    For the downvolting part, like most of you, or at least for what i have read, i can't go under 0.75V either, take it as a confirmation of what was stated before.

    Now the interesting part; my problem is that i think Ati Tray tool is not working properly on my system.
    I tried of lot of voltages and when i try to go as low as possible with the stock clocks something strange happen.
    I can reach 680/900@0.951V without any artefact on the 3D renderer and on the furmark bench.
    But when i try 680/900@0.950V no artefacts or anything it just crashes, i get a black screen for a few seconds, then my desktop partially comes back for a few seconds and it crashes again...
    I have the same thing at 740/900@1.001V it crashes at 740/900@1.000 but this time i get a red screen... but still no artefacts 0.001V before, which i find really strange, going from working perfectly fine playing the witcher 2 for 1hour (740/900@1.001V), to just crashing as soon as i get to 1.000V

    And with ATI tray tool i can't get my memory clock to go over 945Mhz no matter what the voltage is, it crashes... i can't even get to work fine at 710/1000@1.1V with Ati tray tool whereas with CCC i can do it. With sapphire Trix i can even get to 800/1000 without any problems...

    So i can't figure out why, why can't i get 710/100 to work with ATI tray tool, when it's perfectly stable with CCC...
    Why do a 0.001V difference crashes without having any artefacts before?


    I hope this comment might help you correct a bug, if it is one, or simply make the program easier to use by highligting what have to be done (if i didn't do something properly)
    I also hope i have been clear enough, i would really be grateful to get some feedbacks on that matter.

    This could be a problem in voltage and how ATT sets it. Its hard to find whats wrong without such hardware. really have no idea what to suggest you

    Thank you for your answer,
    I came to a similiar conclusion with the 0.001V variation which makes me crash...
    But i think it's not the only problem. I can only guess, but it seems that something is wrong with how the memory clock works. Because i can overclok my mermory with sapphire trix and CCC but no matter what voltage i use, i can't go over 940mhz or so with ATT.

    I guess, for the time being i m pretty much srewed :D

    I will patiently wait for a new release that might help me. i will still use ATT since despite that problem, i still can donwvolt my graphic card to a useful state.

    thank you for your work on this very usefull tool

    ATT does have issues with down clocking/volting when you set up a profile in it.

    With my system, if I set a "always on" 3d profile in ATT (Max default clocks and voltage) but play a Youtube video (Which auto down-clocks and down-volts) I get a freeze. However if I don't set a clocks profile in ATT but do set one in CCC and configure a hotkey for it, my card downclocks fine in Youtube (Flash) and I get no freeze.
