Have they come out with anything to overvolt the 480 yet?

    been many threads on this since the preorders but the only answer we get from evga is it will be out in a bit. if you want mes with it, msi afterburner will do it but that isnt covered under evga warranty

    That's just an EVGA skin for MSI Afterburner which, like hombre said, isn't covered under the EVGA warranty.

    EVGA plans on releasing their own program that has software voltage control for the GTX 470 and 480.  They have to work the same as Afterburner, since that's all you can do with the NVIDIA VGA BIOS.  It will probably be designed by Unwinder too, he designed Afterburner, Rivatuner, Precision, and most monitoring softwares we use.

    1.138v is the max.  I'd like more, but you'd have to hardware mod for that.

    I don't understand why Afterburner would void the EVGA warranty.  It along with Precision are coded by the same person, and they will both ultimately be using the same code to get the same job done.  The only real difference will be the GUI.


    Are you guys sure Afterburner voids the warranty?

    When EVGA is coming out with their own way to over volt your card, I don't think overvolting will void your warranty. EVGA prides itself on its customer service i doubt they would deny you for using a program when its only difference is the programs name starts with MSI instead of EVGA.

    Although I could be wrong, this is probably something for jacob to answer.

    Afterburner is not designed specifically for Evga ,so of course it can void the warranty.

    Evga's voltage tuner will have a maximum voltage ,if msi afterburner exceeds that max voltage then of course it'll void the warranty.

    What are you talking about?  EVGA cards are Nvidia cards.  Afterburner IS designed for ATI & Nvidia cards.  Afterburner has a very low voltage voltage limit of I believe 1.138v.  The same code afterburner uses to overvolt the 470/480 made by Nvidia will be the same code used by EVGA's overvolt tool.  They are the SAME.

    Correct, except the voltage limit is not because of Afterburner, it is the max the VGA BIOS allows.


    @ iride4u - why?

    This is not true, Nick F. from Evga said, they will cover it.  You can over volt these cards, it will NOT void warranty

    All I know is that I got this direct from EVGA support.

    "Using any original EVGA program to work with the voltages fro your graphics card will not void the warranty. Using 3rd party program is not supported."

    Over volting may cause a corruption of the OS if you keep it too high and don't have enough cooling. But you can also get some amazing results from raising it.

    Well, EVGA does not specifically say it in the warranty I posted above.  Also, one poster above said that afterburner is covered.  This is most likely once again because the same programmer programs afterburner as does precision and any EVGA overvolt tool.  I would hardly call that an unsafe, unknown third party.  That is why they warrant the use of afterburner.  To say they wouldn't warrant the use of afterburner would be taking away faith in their own overclocking software because once again, it is the same programmer.
     
    Use afterburner and be happy.  It "is" covered.

    Anyone using Afterburner should be very carefull. I suggest using Precision to acheve as good a OC as possible. Now run Afterburner and try the higher clocks and voltages but do not have them saved on boot.



    Why is it bad to set afterburner to OC at boot

    Because if you overclock your card, and it becomes unstable and crashes, then whenever you boot up your computer, you crash.

    I do agree, but it isn't the end of the world.  The GPUs won't even be stressed enough upon reboot to cause the system to freeze or blue screen no matter how unstable an OC is.  Also, if for some weird reason it would happen to not allow you back into windows, you can always boot into safe mode, uninstall afterburner, restart and reinstall afterburner.

    1.138v is the max.  I'd like more, but you'd have to hardware mod for that.

     
    You don't have to mod hardware for that. 1.138 is the current GPIO voltage limit in reference VGA BIOS for 480 series. Real maximum voltage, which can be reached on 480 series via GPIO software control is around 1.2V. So it is possible that some vendors will release custom BIOSes with extended range allowing to set higher voltage. Also, CHL8266 (480 voltage regulator) can be re-programmed via I2C bus, this will kill power management (i.e. there will be no 2D/3D voltages) but this will also allow setting voltages up to 1.5V. Currently there are no public tools allowing to control voltage via this way (direct VRM programming), we have this mode implemented in Afterburner but it is disabled for public and will be unlocked in extreme version only provided by MSI to hardcore overclockers and overclocking parties.

    I agree, no point giving the public the ability to over volt above 1.2.  I doubt water cooling solutions could go much higher than 1.2.  Anything over that is going to be sub zero cooling.  If you are dishing out for phase change cooling, or doing suicide runs with ln, I doubt you are going to mind one more email to ask for the unlocked version after all the trouble of getting an extreme setup built.

    I was just saying that that is generally why you avoid doing that. It can save you the hassle of trouble shooting.

    1.138v is the max.  I'd like more, but you'd have to hardware mod for that.

     
    You don't have to mod hardware for that. 1.138 is the current GPIO voltage limit in reference VGA BIOS for 480 series. Real maximum voltage, which can be reached on 480 series via GPIO software control is around 1.2V. So it is possible that some vendors will release custom BIOSes with extended range allowing to set higher voltage. Also, CHL8266 (480 voltage regulator) can be re-programmed via I2C bus, this will kill power management (i.e. there will be no 2D/3D voltages) but this will also allow setting voltages up to 1.5V. Currently there are no public tools allowing to control voltage via this way (direct VRM programming), we have this mode implemented in Afterburner but it is disabled for public and will be unlocked in extreme version only provided by MSI to hardcore overclockers and overclocking parties.


    Thanks for the info update unwinder!  Sorry Evga....might have to get an MSI

    Are you going to be sub-zero cooling suicide runs or something?  If you are, all you have to do is flash the VBIOS.  It isn't hard.  Sure, it will void your warranty, but if you're doing those time of benchmark runs, I don't think you really care about that.

    Nope --> No reason whatsoever to go MSI...  Just flash the BIOS to that of the MSI extreme cards when they come out.  I'm sure the BIOS will be available to download ASAP once it is released.  It will take you 5 minutes to do.  When you are done doing your suicide runs and if your card is still operational, just flash the original EVGA BIOS back so you will then retain your limited lifetime warranty.  Using VBIOS flashing tools, you have to option to make a backup of your original right before you flash it to the new one.  Also, you can just download it @ techpowerup.com.  They have a list of "all" the VBIOS versions for both ATI and Nvidia available for download.

    Yea, you're probably right.  Just trying to nudge Evga to allow us to get access to the 1.5v. 

    But I bet even if you flash to the future MSI vBIOS, it will still be limited to the original card's 1.2v.  This happened to me before when I flashed a xfx 5870 with an Asus bios.  Regardless of the vBIOS, the original manufacturer's limits, in this case xfx, still applied.

    What do you think?

    Edit:  and Yes on the sub-zero suicide thing

    When I flashed my vanilla XFX 5870s which had orginal clock speed limits of 900/1300 to the "unlocked" ASUS VBIOS, those limits were taken off, and the sky was then the limit --> actually I think it was 1400/1500 or something like that.

    You probably flashed your 5870 to a "locked" ASUS VBIOS.

    When you flash the card to another manufacturers VBIOS, the card is basically read as that manufacturer.  My 5870s then read as ASUS GPUs.  None of the restrictions set in place by XFX were still in effect.  They had essentially been ridded of completely by the new "unlocked" ASUS VBIOS  The same will apply with the Nvidia cards.
