    GPU overclock

    hello,

    I recently began overclocking my 8800 ultra card (GPU, memory, and shader). However, I've run into a few problems wrt testing.

    With some 'stress tests', my temps are reasonable (I think). They peak at around 83C. However, with Furmark and ATITool, they will steadily climb past this point. The cooler (100% fan setting) does not seem to be able to keep up. Should I reduce the frequency of the GPU?

    Also, with the ATITool artifact scanner, it continues to report that no errors have been found, yet I still get a few yellow dots on the screen (I assume these are highlighting artifacts). What exactly does this mean?

    EDIT: Under ATITool, the temps climbed to 91C max in about 30 min, and for the past 5 min it's been hovering between 90/91C.

    Try and angle another fan at the reverse of the card. Clean all air vents.

    Or ebay your card for £90 and buy a GTX 260 for £110

    edit: 90C is officially "safe" but I only took my 8800 to 80C

    Re: GPU overclock

    If you are having 'yellow dots' then you need to bring the overclock back a little.
    As for the temperature, 90-91C is not a killer but the life expectancy is decreased.
    Extra cooling is advised.
    The 'yellow dots' could be an indication of temperature. If you have a desk fan take the side of the computer and direct it at the card.
    This will help cool things down.
