    Just as the title says, it works!:)
    I tried one MXM 3.0b GTX 1070 , which I found new and relatively cheap on feebay and it worked like a charm. I put some LM to the GPU - 75-77C max after half an hour of FarCry 5.
    Some pics and benches:

    Nice! Looks like a 115W 1070N from the Heaven score (Fire Strike is too low-res to read), which might be the first time I’ve seen a 1070 in standard MXM-B that is not Max-Q.

    Yes, 122W max on load.

    Nice. Have you tried overclocking yet?

    It already runs at 85C, no much temp room for OC I think...

    The card is TDP locked, so OC won’t increase temps, it’ll simply run high clocks at lower voltages. Pascal/Turing OC is quite different from OC on previous architectures. It’s more similar to undervolting.

    Looks good. Your Heaven score is what I expected, but the FS Graphics Score is a bit low (the OCed score should be what it gets at default), I wonder why. Also I would up the memory OC to +500 in Afterburner as well, as the the GTX 1070 is quite memory bandwidth starved due to using GDDR5 instead of GDDR5X, and those Samsung 8Gbps GDDR5 chips are good for at least 9Gbps.

    Is it possible the CPU to hold the GPU back? (Thats why it gets lower FS graphics?)
