    got two today 8AM :D

    Did some OC.. with MSI afterburner unlocket went up to 1275mhz/1650mhz.
    Even with higher Vcore it didn't want to go higher than 1300mhz!
    But thats only tested with Furmark. Crysis Benchmark wouldn't run. had to settle down to 1150mhz/1600mhz for Crysis to run stable! 5760x1080pVeryHigh8xAA 43FPS ^^ standard Clock is 37fps.
    btw 1920x1080p i get only 60% GPU usage on both!
    Oh. and did a Unigine heaven, 1920x1080 max. Standard
    haldi.square7.ch/Data/Benchmarks/unigine2.5_20120110_0907_HD7970CF.html
    And one OC'ed in EF
    haldi.square7.ch/Data/Benchmarks/unigine2.5_20120110_1319_HD797CFOC.html

    well, looking forward to XFX black edition! Selected chips and they're said to work 1400mhz(1300 for sure) without vcore increase!

    Now this is where 7970 distances itself from an older CF:

    HD 5870 CF overclocked to 890/1290
    Max setting 1920x1080 extreme tesselation 16 aniso 4x AA.

    FPS: 40.4
    Scores: 1016
    Min FPS: 14.9
    Max FPS: 113.3

    This is in contrast to regular settings 1680x1050 where it was real close.

    Anyone encounter a odd issue where the voltage doesn't seem to work properly?

    The Voltage lower down to 1.2 when I run furmark or any 3D application, but remain 1.28 when its idle..

    WTF? I am confuse here...

    This is the first time I have seen this issue, but not with my 6970... only on 7970...

    I dont have this issue, weird though on how it works for you. have you check the voltage using gpu-z? What's the value under load and idle? are you using MSI AB 2.2.0 beta 10?

    in MSI AB, my idle voltage is about 0.9xxv while load voltage depends on what we set.

    the voltage is 1.17 in GPU-Z when I run kombuster..

    In Afterburner its jumping around....

    I got the same max reading in gpu-z, guess it needs an update for HD7970. so you are currently using the latest MSI AB (2.2.0 beta10)?

    yea...

    MSI AB shows the voltage keeps going up and down...

    Do not enable voltage monitor if you're newbie and have no ideas what to expect from it. 7970 VRM are equipped with true voltage sensors, allowing to measure actual voltages on GPU instead of just shouwing you target values like the majority of graphics cards, Afterburner shows readings from voltage SENSOR, currently available GPU-Z is showing target volgtage only.

    this ain't the odd part.

    even without changing the voltage, the voltage monitor in AB is giving me something still surpass the stock voltage setting.

    Which at the end, it seems the voltage control have little to no effect for some reason.

    Try to read the previous reply slowly! Once again, there are voltage SENSORS on these cards: they are able to monitor actual voltages (which tend to fluctuate around target are never static) instead of showing target VID.

    That should mean better voltage control, right?

    It means nothing but different monitoring approach, real voltage vs target voltage monitoring. And a lot of confused noobs ;)

    Sorry, it appears to be my card to be defected...

    tried on other 7970 the voltage range didn't go insane, which goes from 0.8 to 1.2 and gave me lower voltage while I am in 3D mode....:3eyes:
