    Then someone figure out how to fix the thermal throttling temp.

    (They're also not the same cards - the mobile version has more cores than the desktop version, so they're only similar in name really - another pretty big reason not to try & flash a desktop 1070 vBIOS to your mobile I think.).

    Thermal 'throttling' is a thing on desktop too, here's what my desktop GTX 1070 does with voltage slider at 50% and an 87Mhz core offset overclock (increasing the voltage slider delays throttling to slightly higher temperature throttling points, which is a good thing):

    Temp__Clock___Voltage
    <50____2088___1.081
    <55____2075___1.075
    <60____2062___1.062
    <65____2050___1.050

    The author (or someone else) already flashed a desktop bios into a laptop, and the card actually worked. There was just no video output (edp? ldvs?) because the desktop vbios doesn't support that output.
    Again, HDMI may work (miniDP will not).

    And I honestly feel I should say it again: someone should really consider moving this thread to a higher traffic section because this is a rather important and significant thread. I feel that it being buried in the Clevo section (especially since MSI users are buying hardware programmers too) is limiting exposure.

    I'm not super fussed about flashing desktop 1070 vbios onto the notebook GPU.

    Someone needs to look into this thermal throttling thing and at least let me bump up the threshold to 60.

    Removing the thermal throttling points would be interesting, but I think it's difficult to do & not without drawbacks. If I remember rightly I think Prema managed to create a special vBIOS for Mr. Fox that prevented thermal throttling, but the side effect was vastly increased power usage - I'm a bit vague about this recollection so might be wrong, but might be worth your while searching notebook review along those lines. (associated with Tornado F5 laptop thread I think)

    I just want to bump it up a bit....and by "a bit" I mean 6 degrees.

    The differences are way more than that. A desktop vBIOS just wont work on a MXM card, at least not that easily. If this was the case we would have been running the XOC BIOS by now. :)

    Something on the lines of not being able to use the EVGA Classified BIOS on any other 1080 ;).. could be wrong about the Classified part tho.

    Time to keep a tinkerin' with the vbios then!

    It will be nice to see the card running at a fully stable clock.
    But the dynamic throttling clock is not really that bad.
    It can be mitigated by adjusting the clocks locally.
    For example, at the same temperature adding +189MHz globally resulted in 1999MHz at 64C:

    By adding slightly higher offset after a desired voltage can help maintaining the clock that you like. Below showed a 25MHz increased clock also at 64C: freq_compensate.jpg
    You can run Heaven or other stress tests to find a balance point.

    Even though at 1.050V, the 1070 can eat out 270W through the MXM port... :p
