    Again...U cant go lower then 0.825 volts..no matter what u do..u can use nibitor and set something like 0.700 volts..but its only TEXT, if u use an multimeter u will see that u CANT go lower then 0.825 volts...Thats the Lowest u can go..TESTET with multimeter..

    My current GTX 280 is the only card I've got a higher overclock with undervolting. When I first bought it I run the stock-voltage maximum overclock and it was:

    GPU 713
    Shader 1458
    Memory 2754

    I voltage modded it and liquid cooled it, preparing for a big push, but no matter what I tried, I didn't gain anything further. So I cleared the voltage mod and returned to aircooling. Recently I've been struggling to cool it with the aircooler and decided to undervolt it. To my big surprise the overclock didn't decrease! In fact those clocks were stable even at 1.05V, but I found that at 1.0875V it is increased, making 1512 shader stable that wasn't before.

    Stock voltage: 1.1875V (reported) and 1.232 (measured)
    Operating voltage: 1.0875 (reported) and 1.156 (measured)

    guys i have palit gtx460 sonic platinum SLI

    this are my def settings of bios i saved it with gpuz

    [​IMG]

    [​IMG]

    my cards are both VID 0,962 800/1600/4000 loaded and goes to idle1 at 0.962 and idle2 0.875

    what i want is to unlock table to 1,2 max and fan to 30%

    do i have to only change to 1,2 and fan to 30% save the .rom and flash with nvflash and thats all ?

    thanks for the help :up:

    First your bios is corrupted , the checksum is red , save your bios with NVFLASH. The guide of bios flashing explains how you do that.(nvflash --save(File name that you give .rom) (enter) = this command makes a save of the selected GPU BIOS. ( do this before you flash your new BIOS, so you got a backup of the original).

    The fanspeed is changed in the "Fan" tab, change the minimum and maximum to the desired level. If you want that the minimum speed of your fan 30% is , set minimum at 30%.
    The voltage unlock, so you can go to the maximum voltage is in the "Voltage settings" tab = "Max Table Voltage".
    ALWAYS SAVE AS .rom file and that is it.

    EDIT:
    I found your bios in the VGA DATA base of techpower http://www.techpowerup.com/vgabios/
    I modded it to the desired levels you want , download here (the file name is GF104.rom) http://www1.zippyshare.com/v/79813554/file.html

    Is it possible to change the bios on a GTX460 what i mean is, to use the GTX560 bios on a GTX 460? in order to have all the cuda cores working on it.

    i dont think so.. im very very shure, allmost 100% that u cant do this..These cores are laser cut...so u wont be able..and the rams are different from the normal gtx460...

    so i can ashure u it is not possible..

    +1 on BetA13's view.

    And I didn't see a bios of the GTX560 , so I can not compaire to a bios of GTX460 , the P-levels might be different.
    It's like the GTX480 and 580 are so differend in bios layout that it is just not possible to use a bios of a 580 or even a 570 on a gtx480.

    UPDATED Download package

    NiBiToR 6.0 for GTX570 and 580 is now public so it is in the download package.

    For the GTX560 you need newer version 6.01 (donation on MKVtech) , also NVFLASH needs a update for this card I think, but it is not yet on the net.
    For the people thinking of flashing a GTX560 bios on a GTX460 , it is possible with forced flash , but voltage levels and P levels are differend. So I would not do it , the only thing that changes is the clock speed and voltage , you WILL NOT UNLOCK MORE SHADERS OR CHANGE NAME OF THE GPU!!!!

    Some info on GTX560ti bios:
    The max default fan speed is set at 70% and minimum at 40% , it can be unlocked to 100% with NiBiToR6.01.
    The max default voltage is 1.15V , this is the max voltage that you can go with software. You can unlock it with NiBiToR6.01 to 1.213V.
    The default VID of the 3D is 0.9625-1.05V , so this means that the minimum and the best GPU's will use 0.9625V on stock voltage. It is possible that it will need more then this depending on the quality of the chip. The VID voltage varies between 0.9625-1.05V.
    2D and 3D lower clocks is set at 0.95V.

    There is no "setting3" voltage like on the gtx570 and580.
    And the p-levels are = P3(2D) , P7(3Dlower) , P12 (3Dperf).

    The "bumped shader" is calculated the same way as the GTX570 and 580 and changed in the same tabs as the GTX570 and 580.

    I updated the guide for the GTX560ti , you can only edit this gpu with NiBiToR6.01(not public)

    Bummer I guess the Fermi BIOS editor doesn't support the GTX 580....I wanted to experiment with it a bit.

    Huh...strange...it won't recognize my stock (EVGA fan unlocker) BIOS modified or unmodified but will the original EVGA one from TechPowerUp. My bad.

    "Fermi bios editor" supports , GTX460 ----GTX580 , (Not GTX 560ti)
    The NiBiToR that is in the download package (6.0) supports up to 580 and lower.
    For the GTX560ti you need NiBiToR 6.01 (not public)
    It is possible that modified bios versions like the one with fan unlocker (EVGA) the cheksum is to longe and won't be recognized) Better to use original bios and edit it for fan unlock.

    Could be. I used the original BIOS and set my own clocks, vcore and fan range. Runs like a champ at 850/2050 1.037v

    Just to highlight that the GeForce GTX 560 Ti owner can also tweak their BIOS with NiBiTor, being v6.01 which is available after a simple donation. This is just as such to keep the development going and to add extra features. So you have the choice. ;-)

    Hé welcome Mavke , I did post it that for GTX560ti the new NiBiToR is needed , I also put the link(first poste) to your site where they can find it.

    You said:

    "-I did find that with GTX570 , 580 and GTX560ti that when you put in tab 0 and 1 the same value as the new shader speed (tab3) in the P15 level the overclock was more stable , meaning that "the driver not responding" message didn't appear so fast after a oc."

    What are those 2 tabs for 0 & 1, wouldn't it cause a conflict because in a default bios they are different from tab 3?

    edit: nerver mind i guess, i see more people doing it without getting errors or conflicts.

    In stock NVIDIA bios they are the same , only factory overclocked bios version the tab 0 , 1 keeps the NVIDIA stock shader speed and tab 3 the new one.
    EVGA does change tab 0 , 1 and 3 in there factory overclocked cards(all exual values) , this is differend from other vendors.

    Yep i know, i was talking crap, apologies for the quick comment because i was looking at my bios and it isn't default :bang:

    edit: well Shaman cooler installed and running my GTX580 @ 900/4200 and on 99% load my temps fluctuate between the 55-57 degrees, 1.100V

    920MHz needs 1.125 but the gain is 6FPS more but temps climb towards 60-63 degrees max, i like the sub 60 degrees because in the summer it will get 10 degrees warmer so i'm already prepared for that because than my GTX580 will stay sub 70 degrees celsius.

    Good luck overclocking the GTX580 guys, c yah around
