    Capture voltage function has nothing to do with your issue. Capture voltage is for some card that can't be adjusted voltage properly, you already can adjust voltage so there's no problem at all. What you encounter is GPU constitution, I mention many times that Afterburner support up 1.3V but not every GPU can hold high voltage, some can hold 1.35V+, some will crash at 1.2V, just like CPU.

    hmmmm i have not tested myself but whats this i hear adding volts to the 480 does not work on xp?
    its late now i will test later...but if so any hints on getting it to work for xp?

    No hints. I've already mentioned above that voltage control on Fermi series is handled entirely by NVIDIA driver. So if the driver provides support for that - it is working as is, otherwise you're out of luck and nothing can be done to get it working. I've also mentioned that we will not provide low-level driver independent voltage control way for these cards due to the reasons given above. Furthermore, NVIDIA strongly recommended all partners to rely on NVIDIA driver only for voltage control only on Fermi series so the chances to see low-level voltage control implementation are close to zero.

    Don't be a lazybone and read the first posting. Allowed voltage adjustment range is provided there.

    Guys, I've created really tiny test application allowing you to see the status of NVIDIA driver's voltage control interfaces. It can verify if NVIDIA voltage control API is functioning properly and it can display full set of voltages supported by NVIDIA driver as well as show currently selected voltages for 2D and 3D modes. So it would be interesting to see the report captured with this application on XP systems (where NVIDIA presumable don't support voltage control of Fermi) and on 470 systems.

    ok i'm game.... will report back.
    if a few want to report back before me(this evening) it would be nice too.
    edit*
    i tried to get the word out at xs so we can can some reports for you.

    My old good friend Fiery (Everest dude) just captured the report on GTX 470 sample:

    http://www.lavalys.hu/tamas/gtx470_volt.gif

    As you can see, official NVIDIA's voltage adjustment range for this card is 0.825 - 1.087V. So I guess that we'll provide 0.825 - 0.1075 range in Afterburner for these cards.

    Unwinder, it would be handy for the guys who use hot keys and run with Afterburner minimised in the task bar (like me.) if there was some kind of indication from the minimised icon when a hot key press was actioned.

    Keep up the good work by the way!!

    Good news, beta 5 with GTX 470 voltage adjustment support has been sent to MSI a few minutes ago. So it will be unploaded soon (probably just on Monday, as I'm not sure if Garrett is working on weekends). The range for this model is 0.825V-1.087V (that's full range supported by curently available NVIDIA BIOS and drivers). I've also extended GTX 480 voltage range a bit and shifted the limits to 0.825V-1.138V (absolute maximum of NVIDIA BIOS and driver).

    Hey guys...love this tool!!

    Is the maximum GPU/Shader set by the Nvidia drivers? Currently the slider maxes out at 913/1826. I'd love to see a 1000/2000 or more. So far on water and 1.025V all the GPU/Memory is at max settings.

    Thanks again!

    The slider limits are defined by MSI hardware database personally for each graphics card model. Currently it is 130% (in reference to default clock) for Fermi series, but I think that we will tweak it to 150% in the final build. That should be both safe and enough for agressive overclocking.

    lol I know...I posted before I even asked you! Thanks guys 150% would be more than enough!

    does this help me get closer to my goal of ab adding volts on xp for the 480?

    From this report I'd say that it should work as is. P-state and voltage tables look absolutely valid, so unless there is some internal bug in XP driver, it should work. What's happening when you're trying to change voltage under XP?

    i'd say your right,it works!
    wtf? who was the guy who said it dont work??? he must have been half asleep.
    works on both cards....thanks again you sooooo da man my man :)
    i'm sry to waste your time

    Also, I've just noticed that your voltage is set to 1.05V for performance 3D and low-power 3D states. Is that your default voltage? That's werid, because my sample is set to 1.0V by default. If there are differently volted GF100 chips on different cards, that could explain why some users are reporting that GF100 is HOT and others claim that it is never reaching 80C for them.
