    I have strange problem with my PNY Verto FX5900 Ultra card. If I have fsb 300 mhz, I can overclock my card to 530/986, when Iput fsb over 302, I can run benchmarks like 3DMark03, but marks drop usually over 2000 points. If I try this autodetect thing says something like 443/833, but with 300 fsb autodetect says 515/969, and then I can run tests with those 530/986. Why the performance is dropping so much? I can run my system over 310 mhz fsb with no problem, so that is not the problem. My system:
    Abit IC7
    P4 2.4C
    KHX 3500 2x256 megs
    PNY Verto FX 5900 Ultra 256
    Enermax 350
    I use fixed mode with Agp/Pci, so it isnt the problem

    I think the core can throttle itself if its being pushed too far, i've seen it mentioned in a few reviews, not sure if it's been confirmed?? Not certain if thats what your seeing, thought it was worth posting anyway ;)

    it throttles down if it gets too hot... fx cards do this...

    it will throttle down, but the throttle down temp is set to 140c.

    I think it is not temperature problem, the card is waterchilled, and even when the temperature is between 14 -21 c, the problem exists
