    Nice, what kind of card do you have?

    I wonder why there was all the talk (from a supposed reputable source too) that 1000 MHz + will damage the card in a short time?

    Also, what vGPU are you running 24/7? What kind of extra cooling for the PWM are you using? I'd be interested to know since it's lived so long.

    I'm running my 8800GT since Jan08 with 1050MHz Memory
    I can run 3DMark06 with 1172MHz, no problems so far



    Still i'd like to figure out the Mem-mod for my ECS 8800GT
    any help? largon?

    Today i added a switch. I benched up to 1.45V, and the card did run until today with 1.36V Idle. Now I'm able to switch while running between 1.1V and 1.36V, saves me 10W
    All cooled with an AC S1. The PWM and Memory is cooled with an extra 120mm case-fan.

    ignore the dust

    pest,
    Please measure resistance between pin#4 and pin#7.

    The vMEM mods are likely identical to those for the reference card (regardless of fact that the chips have different names): vMEM, reverse vMEM.

    You were not supposed to see this.

    it's a non-reference card, but the memory-controller should be the same?

    second problem is that i don't know what memory-chips this card has,
    but i guess it's not quimonda because the cooler the better the memory clocks
