    The 120Hz 1080p screen is a brand new model and there are no published specs that I could find for it as of Saturday. It is an AUO B173HAN01.2 AHVA. Has anyone found detailed specs for this yet?

    If the 4K screen is the same one I had installed on the Sky X9E I really hated it. I'm glad I don't need 4K for anything because I thought it sucked. It looked like crap set at 1080p and the refresh rate was still gimped at the lower resolution. Then again I have hated every 4K laptop I have tested, so it's not only this one that sucks. I have found all of them to be totally miserable.

    wait you're talking about x7200 or p870dm2. p870dm2 the gpu heatsink goes ontop of cpu heatsink so heat would be shared that way.

    That could very well be NVIDIA's signature vBIOS cancer that has been a thorn in our flesh since at least the Fermi days. GeForce mobile cards always runs like crap with a stock vBIOS. @Prema may be able to fix that by raising the TDP max to 250W - 300W. At first blush, I'm going to guess that 150W TDP is simply too low to function correctly. It may need at least 200W TDP per GPU to run without throttling at stock clocks and probably at least 250W TDP to overclock without throttling. Then the effectiveness of the new monster cooling system will get put to the ultimate test with an additional 100W TDP per GPU to achieve full performance potential. Should be interesting to see how that shakes out. Hopefully, they engineered it to effectively manage thermals at least 300W per GPU. The 200W 980 hits 300W with unlocked Prema vBIOS when heavily overclocked. I'd expect nothing less from a 1080.

    My 1080 AMP runs around 65c with Liquid ultra + custom fans (1.093-1.094v) - around 275-290w constant power draw under DX11 Witcher 3 Ultra 4K load. This is with power limit fully disabled but has no way to disable the -13mhz throttling everytime break above 50c.

    1.2v it runs at around 310W, have concerns (read below).

    Keep in mind that the pascal cards.

    1. VERY sensitive to thermals
    2. Lowering power limit and thermal consumption might net you higher clockspeed
    3. Runs hotter in theory because of smaller substrate with more transistors
    4. Don't really care about voltage, temperature matters more. Ideally below 50c.
    5. More voltage can mean less stability, I'd say don't go above 1.093v.

    Prema stated that automatic fan profile never goes above 60% of the maximum fan speed. So when setting it manually to 100% the throttling of card 2 might not happen, at least I hope so. Noise will be a different story. Unforrunately the fans on the P870DM3 seem to be smaller than on the old modell. I hope this will not be the root of the proplem...

    The P870DM2, of course.

    In regards to my comment, a GPU would have to be generating a lot of heat for that to be a problem. In my work, I don't think I've seen a GPU temp past 45 - 50C. A shared heat sink would introduce a new variable, but don't believe the 47C temp from a single GPU would affect an hex core enough to induce throttling. Now, if they made one (6 or 8 core CPU - LGA 1151 - Z170), I could tell you.

    Also, there is the 'shared' heat sink you mention. Can anyone confirm if there are heat sink differences between the P870DM2 vs. the P870DM3? My understanding is the P870DM3 has the new T-design heat sink / thermal plate to help dissipate heat where GPU and CPU are shared heat sources. I thought I read the P870DM2 has a different configuration where CPU and GPU heat sinks are isolated - much like the original P870DM.

    http://www.panelook.com/B173HAN01.0_AUO_17.3_LCM_overview_26291.html

    AUO B173HAN01.0 is 6bit + FRC . But at the same time it was 60Hz instead of 120, maybe they increased bit depth. What makes me hesitant to believe this is the fact that increasing bit depth usually increases the bandwidth needed thus it's a bit unlikely that they increased bot bit depth and refresh rate.

    But it''s all an educated guess at this point.

    BTW, for 1.0 version, in panelook, they do write that it is 25 ms response time panel.

    IT seems that the refresh rate has nothing to do with the response time for 99% of laptop displays. I mean, almost every laptop display advertised as 60Hz has a refresh rate higher than 16ms, which would be the minimum for 60 fps. The old LG, that is found in all 9XX high end laptops is the same. It's advertised as 60Hz, but it's response time is 25ms typical.

    Most laptops, I mean almost all laptops in this world touch ~80C on GPU and depending on CPU, ~95C on CPU.

    Desktop cards run much colder.

    these exact points already bother me with maxwell! if pascal is even MORE sensitive to overvoltage and temps, that would just be super unnerving :p

    I buy 4K then


    @jaybee83 - I might have to remove the power mod on my zotac 1080 today, thing's unstable as hell even below 2000mhz
