    Whew, that's enough modifications and hacks to get an additional ~10-15% gain for my risk tolerance.
    Spent $35 to get half dozen matching part number EEPROM chips from some back alley Chinese site that has a 1.7 Star rating on Trust Pilot.
    As soon as I reprogram the EEPROM, all passes with flying colors. Verdict is indeed that I managed to kill the chip with 3.3v (after a while though) as I lacked the 1.8v Logic converter.
    But that was just the beginning.

    Yep, as soon as I go remove the chip I manage to snip all the legs only to have the middle mirrored pads just fall off. This was the "Oh ****ake" moment.
    Getting back to my senses after figuring $600 went down the drain, I realized that I'm not an idiot. Followed the pads to their traces and tried the old "remove the silkscreen" method.
    As soon as I tried to remove the silkscreen from the traces they immediately pulled right off. This meant that I had to trace the circuit back to the next via or SMD part.
    Luckily, that managed to be a ~0603? SMD resistor. That would be easy to run a bodge wire from. Then there was the other pad, this one was a PITA as it was only ran to a via in a group of resistors.
    I managed to scrape away the silkscreen with an xacto knife and tin the via without making a bridge between the other components, or accidentally just pulling them off the PCB all together (takes nothing with a proper iron to push those babies right off).

    Bodge wires ran, my mind flooded with anxiety and angst. I manged to get it all together and threw the heat sink back on. To my luck it FAILED to show video output. About to give up, I noticed that it looked like the bodge wire was rubbing on the ground side of the capacitor in the picture above. Carefully I rebent the wire to remove any short. Trying for the last time, I was lastly greeted with the Prema Mod logo. The machine is now back and running. I've never been more happy to have a stock GPU as this. What an experience.

    Hi, can someone provide/link me a GTX 1070 mobile/max-q vbios which allow overclocking (like core and memory frequency tuning) ? I know there is some vbios on techpowerup but I'm not able to know if they are "unlocked".
    Thanks

    You don't need any special vBIOS to overclock using software tools like MSI Afterburner.

    Quadro vbios are locked, I think it's vbios related, but you confirm that every 1070 mobile can be overclocked ?

    GeForce vBIOS is not overclocking locked.

    @Coolane, are you interested in modifying this for the Quadro RTX GPUs?

    VBIOS attached.

    Hi, can you provide GPU-Z screenshot ? (main and "advanced > nvidia bios" section)
    I think I found TDP and temp value, the TDP limit seems to be 80w and the card should throttle temp at 60°c or 66°c
    I don't know why there is a redundancy in the vbios with the same value.

    Do you know from which temperature the card start to throttle ? If the temperature limit can be modified by overclocking tool so I think there is something about the temperature here (on the picture)
