    Hello

    I think, yet I'm not 100% sure that Nvidia? did something to prevent loading drivers on cards with a modified bios.

    At least this happen in my case.

    Yestarday I did a fresh installation of 387.92 win10 64bit driver.
    BOOM, error 43 on a super fresh Win 10 instalation.

    Ok, I did a quick rollback to a 385.41 series and guess that? It works.
    Later I reinstalled again 387.92, the same. error 43.

    I thought that this could be somehow caused by my modified bios.
    Yeah, Im using a tweaked bios with a simple voltage mod, nothing fancy.

    After I rolled back to my original bios, 387.92 loaded fine, no errors.
    And no, this is not a broken bios, os, card or something.

    Whenever I rollback to 385.41 everything works as it should with my modified bios.
    I've been using this bios for almost 2 yeas with no problems.

    md5 checksum dumped from my gpu bios is the same, so it's not a corruption or something.
    This is realy weird, and I'm lost and out of ideas.

    For now I can't use 387.92 with a modified bios

    WTH is going on. o_O

    100% my case here. I can't install the new driver and i've modified BIOS with overvoltage and increased power draw.

    I also modified it a bit - increased power draw limit and overall to match extreme, also base 1278 > boost 1418mhz and works ok.

    Maybe its just voltage specific?

    This is a highly unstable driver. Has introduced many anomilies and strange behaviors in many games, even causes some full crashes.
    From installation to running a game, it seems instable and creates issues.

    I will pass on this one, I haven't seen a driver this flaky since the 353-369 era

    reporting back, flashing the original BIOS allowed me to have the driver working without issues :/

    980 ti here, modified bios with increased voltage and power limit as well as default freqs for P0 and P2. 387.92 works fine on my side.. I don't think the issue is that simple. Did you guys use DDU before trying to install the new driver ?

    I have a gtx 970 pny modded the power draw limit and the fan control.
    Also it is updated with nvidia uefi gop module from 2017.
    (my original hybrid bios has a nvidia uefi gop from 2015)

    I have no problems.

    I just did extra quick test on my old crappy GT 730 from gigabyte.
    Completely different computer.
    Yes, modded bios is causing instant error code 43
    Simple P0 1.2v mod, just for a test.
    No mod, drivers are loading fine. :eek:
    So yeah, it is a driver issue, maybe not a global, but it is.

    Could you share the modded/original bios files, please.

    Modded vBIOS on SLI 980 Ti's error code 43. Tried DDU and every which way to get it to work. No dice. Previous driver is fine.

    If you modify your BIOS and have a device ID mismatch compared to what the driver is expecting, it will fail to install. I have both a 980Ti with voltage, memory and power table modified. I modified it from the original stock BIOS and I have the FTW3 BIOS flashed to my EVGA 1080 Ti FE. Drivers install just fine.
     
    fantaskarsef and XenthorX like this.

    980 Ti throwing code 43 with new drivers as well. I'm running SLI and both were modified from each original bios. I had someone else modify them that was more knowledgeable than me. Any help pinpointing the exact cause would be appreciated.

    Dump your bios here and the orignal bios(or model of exact card you have)

    Of course those don't work.

    The driver is expecting a certain vbios size, which the modded ones you downloaded are a different size than original.

    You run clock speeds at 1405mhz?

    I can guarantee you dont need 1.25v for that

    Unless you confirmed you do need it.

    BTW ill upload a correctly modded bios for you to use.
    If both cards are SC+ then it's safe to force install on both.

    I run stock clock at 1405, and depending on the game I up it to 1460-1500 via afterburner.

    I pushed the cards as hard as I could, but they topped out close to 1500 mhz. Extra voltage beyond 1.25 didn't help, so I left it at 1.25.

    Even though both are SC+ models, the cards have a different version number. I assumed the second card could use the bios from the first one, but it bricked the card when I tried it. Had to modify the original bios on the second card for it to work. The first card is 84.00.32.00.94 and the second card is 84.00.41.00.90

    I've never had a problem with any previous drivers so I don't get why the bios size would be a problem now. The bios were modified with Maxwell bios tweaker 1.36.

    Edit: For clarification, the modded bios are modified from my originals.
