Artefact testers?

  2. Are you using DVI? That looks like a clocking/timing problem to me.

    What does DVI have anything to do with timings of VGA cards? I suppose
    you could give trying the other connector of your videocard.

    As for the OP, supplying with specs could be useful. You'll see
    artifacts/underclockings if you don't have your videocard hooked into
    your PSU (if it requires it). Is it a new card, or did it start doing
    this? Have you felt it, does it feel extremely hot around the memory or
    heatsinks?

    I'm getting a similar problems with my Gefore 6200 Turbo Cache....some
    text sucks (eg the standard XP packaged Outlook Express's "bolded
    folders" text

    i'm really disappointed with the card. I've checked all the connection,
    installed the latest drivers, but I'm still getting some artefacts &
    some ghosting on strong onscreen verticals.

    Can anyone recommend a *quality* 2D PCI-e with dual head output?

    Many thanks,
    Trouty.

  5. hint: what does DVI stand for? It's digital, it has clocks to
    synchronise.

    It's a new card, the card is an MSI NX6800GT

    http://www.msi.com.tw/program/products/vga/vga/pro_vga_detail.php?UID=610

    Mobo: ABIT BE7 P4 2.8 @ 533FSB w/2x512MB ram (memtest86 reports no
    errors)

    OS: WinXP sp2 & Win2K sp4

    Driver: Tried supplied MSI driver, 77.50, 78.05, 81.85, 81.89 and also
    81.94.

    Card power is connected via 4-pin molex, PSU antec 380W truepower,
    measured voltages at connector are +/- 0.05 volts of spec, idle and
    under load.

    ATITool's artefact test reports many frequent artefacts:

    http://img512.imageshack.us/img512/9885/artefacts6bl.jpg

    Core temperature is normal, it idles at about 55deg peaking to about
    70deg under heavy load: atitool's fuzzy cube thing.

    HL2 and BF2 all exhibit random missing / funny triangles, but HL1 etc
    don't show any problems.

    I'm pretty sure it's a shader issue, as if I disable pixel/vertex
    shaders, I no longer get any artefacts.

    The strange thing is, I know the card is fine as i've tried it in my
    Shuttle SN45G with no artefacts and a stable overclock to 425/1150MHz -
    using the same PSU as above, (didn't want to risk popping the shuttles
    crappy psu :D)
