    HD 3850 temperature (?) problems

    Hello,

    stress-testing the new Nexuiz release on my rig makes my system with a HD 3850 have nice X freezes (or black screens) on Ubuntu 8.04 x86-64.

    Booting into windows I noticed I can easily push the gfx card to 92?C without the gfx card fan speeding up audibly (and without crashing). On Linux I once got it to sound a bit like a vacuum cleaner, so I guess the card may get even hotter with fglrx.

    Dumb question: Is there a tool for Linux to read the gfx card temperature? It may be the temperature, it may be some unrelated fglrx-specific thing, but without sensors I just can't tell. I find it rather disappointing that the catalyst control center doesn't offer thermal monitoring (the last card without sensors I had was a Nvidia FX5200...) - but then again there may be bigger issues.

    Some of them were temperature related. Most things didn't work here but my card is pretty old. It's also possible that some things have changed in the meantime

    Thanks a lot for that post!!! I've been waiting for the ati devs to implement fan control and temperature monitor in fglrx without knowing it was already there!
    Code:
    franjva@quad ~ $ aticonfig --pplib-cmd "get temperature 0"
    Temperature for thermal controller 0 is 47.000000
    franjva@quad ~ $ aticonfig --pplib-cmd "set fanspeed 0 55"
    PPLIB command execution is Successful!
    franjva@quad ~ $ aticonfig --pplib-cmd "get fanspeed 0"
    Fan speed query: 
    Query Index: 0, Speed in percent
    Result: Fan Speed: 55%
    Now I can control the fan speed as I do in windows. I wish I had seen your old thread sooner.

    Yeah, I got tired of waiting. And as the update from Visiontek came with an AMD icon attached to the executable I assumed it wouldn't be anything Visiontek-specific anyway.

    not to mention you can OC this baby now its a great OCer. My memory is running at 1100 now and the core is running 770 and it could go higher but I would have to flash to an unlocked version of bios.

    ps. let me quess you grew tired of waiting Powercolor and you flashed with Visiontek??
    the bioses are all the same because ATI themselves have made them.
    This is probably the reason that BBA cards are such great OCers.

    I now flashed the Visiontek BIOS and the card stays well below 80?C. Thanks for the hint, I assume the card may feel much healthier now ;-)

    Thanks for the hints. I contacted Powercolor support and I hope I can retrieve an officially blessed BIOS (so if things go wrong I won't end up standing in the rain).

    As a fun note: The decorative sticker on the card peeled itself off.

    If you're brave you could check out the BIOS collection on techpowerup and/or edit a compatible BIOS with custom fan settings. Incredibly easy to do if you have a spare Windows partition (to launch the BIOS editor since I don't think it would work on Wine).

    then you are suffering from the bios bug. Same as I had.
    You should contact powercolor for an updated bios or if you do not want to wait you could go ahead and flash with this bios:

    some info also available here:

    The bioses for BBA ATIs are all the same. I own a Sapphire card and I flashed it with the above mentioned bios since Sapphire never responded back to my email.

    edit:
    with the faulty bios usually the card will not go over 92C except if you really stress test it with some heavy gaming it will even reach 97C. But by then you should be seing lots of artifacts which was the main reason that I first checked the temps.

    I watched the fan speed on Linux (aticonfig --pplib-cmd "get temperature 0") and the fan is at roughly 44-47% at 90?C.

    Code:
    #!/bin/bash
    for((;1<2;)); do
    echo "----------------------------"
    aticonfig --pplib-cmd "get fanspeed 0"
    aticonfig --pplib-cmd "get temperature 0"
    sleep 1
    done
    gives output like

    Code:
    ----------------------------
    Fan speed query: 
    Query Index: 0, Speed in percent
    Result: Fan Speed: 47%
    
    Temperature for thermal controller 0 is 91.000000

    This may actually be a rebranded BBA thingie, no idea.
