    Not the responses I was hoping for I must admit... Looks like it's time to start my third RMA of the fornight! The temperatures are all staying pretty good so I doubt it's that. The video memory one sounds quite possible actually, it crashed a while back saying it had run out of video memory.

    Considering I was the first one to advise there might be an issue with @makejason 's card then yes I know.

    We are almost 2 years in the number of failures compared to other cards has been totally normal at this point.

    Hi,
    the problem is driver 397.64. My friends and i killed 2x Gtx 1070 and 1x P5000 with this driver in 3 different notebooks. Looks like Nvidia raised the core voltage.
    Try an older Version like 391.35. Maybe the Card will work again normally.

    It didn't raise the core voltage.

    Not you, Nvidia did it with the latest Driver.

    The latest driver did not increase GPU voltage. I game with an OSD and my voltage has stayed the exactly the same on every driver since 391.35.

    Impossible. The drivers cannot raise the core voltage on a card where the vcore is locked by the video bios!
    Even the unlocked voltage slider in MSI afterburner is ignored because the video bios won'to accept the voltage increase.

    But you killed 2x GTX 1070 with the Nvidia driver somehow.
    How come I have yet to kill one GTX 1070 in a MSIbook that is HARDWARE MODDED to 210W TDP ? Explain that? your card is IIRC, 125W.

    No difference in temps or power draw with latest driver.

    That happened, while running firestrike with the new driver.

    Looks like a GeCube/Eurocom GTX 1070 that got the magic smoke while running at 115W.

    There must be some horrible ripple going on for a ceramic cap melt like that, or the cap itself was a Y5U crap, given the current shortage of passives, wouldn't surprise me that its second or third grade ceramics, and it was too much ripple for it, being in the middle of the MOSFET's and thus hotter only accelerated the problem, it might be repairable, at least I would de-solder the cap, clean the whole pcb with IPA, solder a new 10uF 50v X7R 0805 cap and see how it goes.

    If you dont want the card I will pay shipping for her :D (only half kidding).

    Also, did you solder the extra MOSFET?

    EDIT:
    The gate trace comes from the bottom mosfet through a via, the top mosfet in the photo isn't doing anything, the gate trace is interrupted with the pads of a resistor, so, that mosfet was flapping in the breeze, if you soldered the mosfet yourself, lack of gate resistor might be the culprit, even more so if you did the same mods to both cards and you didn't notice that.

    At least it looks like so, there is a via near those pads, but I can't be sure if its connected or not.
