    Changing 16200 to 19200 is required if you want to exceed 200W on the Limit field (16200 limits you to 200W maximum).
    However there are some...driver or hardware oddities which may be due to the specific MSI 1070 vbios and how the original MSI 1080 was first made for a 150W target, rather than a 200W target.

    Some games will power throttle at 150W instead of 200W, even when you selected 200W in the MSI Afterburner slider, when they should be reaching 200W first. PUBG has done this. Changing 16200 to 19200 stops this, but if you set, let's say, a 230W limit, PUBG may still throttle sometimes at 200W instead of 230W. I have not seen this behavior in Heaven or Valley or anything else.

    One thing i did notice is changing this first extreme setting changes the point where the system throttles the GPU on battery power. This can cause excessive GPU load on the battery.

    i mean if i should modify the range 16200-16200 to 16200-19200 or 19200-19200.
    in other words, the extreme fitst def value and max value need modify 16200 to 19200 both?or only the max value do.
    sorry,my english is poor.
    im glad to your reply.

    Extreme power limits doesn't have a 'range'. You enter a value.
    Also there is no documentation for these settings. Because these settings if changed randomly can destroy your hardware.
    I believe that "extreme" settings have to deal with "Amps" or "Current" going through the PCI-E voltage rails, for different power states. At least from what I remember on the "Maxwell/Kepler" desktop vbios editors.

    I also believe that the early "power limit throttling" in PUBG is because of a bug in the MSI vbios. Possibly again due to some relation between power limits and the extreme power limits.

    As you know, the default setting for "GTX 1080" extreme power limits is "16200"
    For MSI GTX 1070 its 14,500.(i think).

    To get TDP higher than 125W on GTX 1070, you need to change the extreme power limit to 16,200, which is the default for the GTX 1080. The problem is, the GTX 1080 (MSI) has 2 versions: a 150W and a 200W card. In fact the original (pre-release) MSI 1070 MXM had a TDP of 150W too. So the way the extreme power limits were coded, were based on the 150W version. The 200W version uses the same settings, but it seems (again, there is no real documentation of these settings) that the 16,200 and the vbios itself was 'calibrated' for 150W somehow. And PUBG manages to somehow flag this and cause power limit throttling if you exceed 150W, even with the TDP set to 200W. The 19,200 value "solves" this, however the 19,200 value is made (at least in the GTX 1080 "preset" button) for EXCEEDING 200W (example: 215W target, 258W limit). But again, sometimes PUBG flags power limit at 200W. I know the "2nd"" extreme power limit also has to be increased (like done on the preset), but again I dont know what relation it is for.

    For example:
    default for GTX 1070 (MSI) is 14500, 181000, 76700 (115W).
    Preset button changes this to 16200, 242000, 137600 (151W-170W). These extreme power limits are the exact same as the defaults for the GTX 1080 (MSI).
    This is good up to 200W, but sometimes PUBG flags power limit at 155W+.

    Default for GTX 1080 is the same (16200, 242000, 137600) (200W).
    Pressing the preset button only changes the target/limit to 215W-258W, and the first extreme power limit to 19200, not changing the other two.

    Yet regardless of the target/limit setting, PUBG seems to sometimes throttle at 200W. "sometimes".
    I haven't seen it do it lately since the last huge patch but I haven't played PUBG in a few months now.

    This isn't repeatable either. It seems to do it when it wants. Sometimes at a certain GPU temperature. Sometimes when looking at certain walls. I don't know and frankly I don't care :p

    Just remember there is no harm in using "19,200", unless you are on battery power, as I found (AGAIN, NOT ALL THE TIME), that sometimes a GTX 1070 gets limited to 65W(!) on an 80W battery, which trips the system and it shuts off (it should be pulling no more than 50W).

    And please don't mess with the other two extreme power limits. We don't know what they do exactly. Bloodhawk does, as well as Prema and a few others, but they are not going to tell you. Because you can seriously destroy your cards.

    Thank you very much for taking the time to reply to me. Do you mean that the value of position one and position two should always be the same all time?
    Another question: why the score is higher when i raise power? i can't increase the core frequency, or the test will crash.it seem +150-160mhz whatever 150w or 200w.[​IMG]

    You can add me on Wechat. Falkentyne. (I am not chinese, so...yeah).
    I'll reinstall it when I'm not lazy. Right now I'm lazy.

    The score is higher when you raise power, because you are not "Power limit" throttling. Power limit throttling causes the core clocks and voltage to drop when you reach the power limit in watts. This is of course for the "TDP slider" in MSI afterburner or the "Target/Limit" values.

    At lower TDP, you can raise core clocks higher, but you will just throttle more.
    Example: at 115W TDP, you can often do +250 mhz on the clocks. Because you will be throttling so much, the card will never reach 2060 mhz, etc except at very very light load or very old games. If you raise TDP, the card will throttle less, so it will reach higher clocks, but then it will be unstable because the offset is too high for the new clocks.

    Again there is no documentation for these Extreme msettings. Leave them at the same values for def and max.

    16200/16200 is good up to 150W. (in PUBG). Good up to 200W (not in PUBG).
    19200/19200 is good up to 200W in PUBG. Good up to 262W (not in PUBG).

    Someone should just spill the beans and explain what relation are these "milliwatt" values to rail amps.
    I mean, 19200 is 19.2 watts, 242000 is 242W, 137600 is 137.6 watts. That is if the "mw" means milliwatts" for each one.

    You might have more success looking over on overclock.net for the two "Kepler/maxwell bios editor" threads. The only hints shown are "PCIE rails".

    I see. Ha ha, I have sent a request to add a friend to WeChat, and you can agree to it when you want to.
    The liquid cooling is modified on my alienware18, so the card temperature is always below 50 C,but i get 20000 graphical score at most.
    Next, I'm going to change 19200 to 16200, that is, the default extreme frequency, and then test the performance.
    I don't play pubg for a while. It consumes too much time. Maybe I will test the performance to play.

    I don't think changing from 19200 to 16200 will change anything (except make the video card throttle more when on battery power, but this depends on your vbios itself) but please let me know. SPI flashing repeatedly is too much for me because the vbios chip is underneath the MXM card, which means i have to repaste with liquid metal every time too.

    haha,you must have a Integrated module,my heatsink is single , so i only need take down the heatsink and card togather.
    but i need remove my liquid-cooling,which link pape full of water.
    i don't know the 19200 is whether safe to the card for long time,so i want take it to default.do you have any advice?

    Based on what you've shown there I'd probably run it at your 170W +150 +500. It's always a good idea to run a max overclock in terms of increasing the Mhz sliders because it makes the card run more efficiently - you're using a higher frequency at a lower voltage, so you're getting more bang for your Watt! That 170W +150 +500 seems to be the most efficient setting, and won't put as much stress on your card as the other higher 185W & 200W versions.
