Using 144 Hz monitors... Tahiti clocks idle at 501/1500?

    Just so you know ATI Tray tools allow you to further downclock your Graphic Card. Msi Afterburner limited my underclock to 325 Core and 200 Mem, however when I used ATI Tray tools I could go to a 100 Core and 200 mem (I could go lower but my normal idle clocks are 110 Core and 200 Mem).
    I'm not quite sure if the HD 7000 Series Graphic Cards are supported though, but the software does have a tweak that shows up when installing to allow unsupported graphic cards to use software overclock.

    Other Thoughts
    Even though a higher res may require a higher Clock it should not need to use a clock that demands that much power to run efficiently. It will just hinder performance when playing games in 144hz since most of the load will be going towards res instead of the game. (Just a thought)

    I use AMD cards, so no lightboost for me. :(

    OK, I just ran some tests. Regardless of resolution, the GPU idles at 501/1500 when set to 144 Hz. I went all the way down to 800 x 600 (and each step in between).

    For all resolutions, it idles at 300/150 when set to 120 Hz, but immediately jumps to 501/1500 when set to 144 Hz.

    Does that tell us anything?

    Yes, now we know why it's called the 144 Hz 501/1500 Clock bug.

    Well, there are some here who are claiming that it's not a bug at all, and that it's necessary to handle 144 Hz. I don't buy that either, but...

    Has AMD ever acknowledged it as a bug?

    After the test with resolution I also can say that its more likely a bug, but still i would like to ask AMD about this whether they are aware of this.


    to paleh0rse:
    What kind of connection do you use? DVI, HDMI, Display port?

    Well, judging from the number post about the bug and no real info from AMD or the Manufacture of your Graphic Card that says the usage of 144 Hz will also result in an increase of your Graphic Card clock. I think it should be considered a bug unless experiments or someone from AMD prove otherwise.

    Other Thoughts
    A good way to find out would be further downclocking your Graphic Card to 350/150 then look for any abnormalities that started after underclocking your graphic card.

    Another Thought
    Raising the resolution should be more demanding than raising the refresh rate. So it's highly unlikely 144 Hz Refresh Rate with a low Resolution such as 800x600 should result in an idle clock of 501/1500.

    I'll try to find a way to under-clock it that low tonight. ATI Tray Tools won't work for me because I refuse to disable UAC; and, even when I did (for testing), it crashed out every time I clicked on the tray icon. It was just giving me too much trouble, so I uninstalled it.

    I'm not at home right now, so I can't mess with it... but, does CCC Overdrive go that low? Does anything else?

    EDIT: By the way, the only real issue with all of this is that it causes my primary GPU to idle 12C hotter than my secondary card, and about 10C higher than it does at 120 Hz... DOH! :micro:

    Ahh, the reason why you may be experiencing such abnormalities with ATI Tray Tools may be because its missing two dll files that allow third party overclocking software to function correctly.

    Here is the link to modded driver for 13.2 Beta 7
    Get the Modded 13.1 WHQL Driver instead from Benchmark3D
    All you will be Testing for, is to see if ATI Tray Tools work Correctly when using the modded Driver.


    Download and install the driver. Windows 8 users will have to enable Test Mode so the driver can be installed. Then re-install ATI Tray Tools.

    I did add those dll's to system32 and Wow64 directories, which allowed the Tray Tools to load and sit in the tray. However, it crashes with a memory address error whenever I simply right-click on the tray icon. It's basically a headache I just didn't feel like dealing with any more last night, so I quickly uninstalled... LOL

    Do I have to keep those older drivers after installing Tray Tools, or will the Tray Tools functionality remain intact if I re-install 13.3B3 or 13.4 after? I'm guessing that the Driver Fusion wipe/reinstall process (Win7 64) may remove whatever allowed ATI Tray Tools to work in the first place?

    I may try it anyways just to test the low clocks, but I can't live without the newer drivers afterwards. My 7870 XT's absolutely thrive on the 13B3 drivers! LOL

    Hmm, when working on the legacy modded driver I've had users report that there overclocking software did not work correctly when they simply put the dll files inside Sys64 and System32 folder. Instead, the files needed to be installed alongside the actual driver. Therefore, I recommend installing modded drivers first before drawing a conclusion.

    EDITED
    I'm not quite sure, the files are usually left behind after a normal driver uninstall. But, I'm not sure if the reg entries remain installed.

    If I can't find anything else that will under-clock to 300/150, I'll give ATI Tray Tools another shot tonight... why not? LOL

    Happens on single card too, as my 290 idles at 300/1250 at 144Hz, instead of 300/150, if i drop it down to 120Hz, then it will do 300/150.

    Its an odd one, as some people on 144Hz with 290s get 300/150. :p

    Strange right? I am not even sure when the issue started.

    Is AMD aware of this issue? Maybe AMDMATT knows more on this?

    My monitor only has D-Sub (VGA), DVI-D, HDMI :(.
    Checked if our IT dept has a adapter from DVI to displayport female.

    As far as I remember on my 7950 it always idled at 501/1500mhz as long as a second monitor was plugged in. Didn't even need to be 144hz.
