    7900GT: 256MB High end not dead yet!

    My voltmodded 7900GT is beating X1900XT's and 7800GTX 512's, at just 1,6v vcore!

    X2 3800+ Manchester, LDBHE 0543SPMW
    DFI LanParty nF4 UT SLI-DR Expert
    XFX 7900GT Extreme, Zalman FS-V7 cooled, vdimm = 2,27v, vcore = 1,610v.
    Corsair 2x1024MB (208Mhz 2.5-3-3-7)
    OCZ PowerStream 600Watt
    VapoChill LightSpeed

    X2 @ 3,1GHz
    7900GT @ 745/2020 (This is 1,4ns ram!)
    Corsair @ 208MHz


    Validation

    12410

    (Singlecard WR)

    This isn't the max by far, and just aircooled.

    The card:

    That RAM is absolutely insane!! wicked sick score, think you can get 13K?
    Microsoft's homepage can be found at: thesource-dot-ofallevil-dot-com - interesting, no?

    Think of something witty and imagine it here.

    can you post pictures of the mod (you replaced resistor 50K, and connected pin 30 to gnd, right?)

    Not to be an ass, but it is the world record for single cards on air right?

    Will take a picture of the vmod soon , I think 13k is possible on air, with some more volts and tweaks!

    26k/27k 03 is possible too

    A 7900 GT has 24 pipes just like a 7800 GTX 512 and 7900 GTX....therefore, when you push it to the same clocks it's pretty much the same. The fact that your GT overclocks so damn good is noteworthy. Congrats!

    I can see that you don't have any problem with overcurrent protection. Do you get black screens with 1.6V? If not OCP mod must work.

    My max core clock is 740 + 20MHz delta with 1.55V and 760 + 20MHZ delta with 1.6V, but after first test I get black screen when test 2 should begin.
    You are as good as your samples are!
