    Nice. My Classified looks to be hitting 1400 max with about 1.4v on the software tool. Don't really want to go higher without a voltmeter. Those clocks on air are fantastic. Never seen that gizmo b4, it doesn't come with the card does it?

    Memory defroster at work

    Short to enable LN2 Mode

    - to use VGA Hotwire
    - BIOS switch for LN2 BIOS
    - Enhance overvoltage range via GPUTweak

    To use memory defroster

    - Short to enable memory defroster
    - 4pins Molex power

    It keeps memories above 0c and off automatically above 10c

    Maximum voltages limit via GPUTweak or Xtreme control board

    Standard mode
    VGPU 1.2V
    VMEM 1.65V
    VPLL 1.1V

    LN2 mode
    VGPU 1.8V
    VMEM 2.2V
    VPLL 1.4V

    The switch to LN2 bios wont take effect without shorting LN2 pads

    This is to ensure it remains in standard BIOS if switch in wrong position by accident from factory as well as to those who know what they are doing to use LN2 Mode

    Try around 1.55V max on gpu tweak, don't go 1.6V+

    Got 1800+/2004 so far

    Mem defroster really helps for 2000+ runs

    Got mine today. 69.6% ASIC, Hynix memory. Is it possible to tell me without voltage increase (stock), can you reach over 76(7)00MHz for the memory? Also optimal safe voltage settings for air - probably for 8000MHz memory? :)

    1.65-1.7 Vmem should be close to enough for 8000 memory on these cards, which in my opinion should be fine for 24/7 use as well.

    For the core, 1.2-1.3V should be safe enough if temps are in check, <65 F under load.
    BorisDG says thanks.
