    You didn't manually enter values in "Extreme power limits" did you?

    Yes i did . . . i copy and past the values from the 0G Vbi0s that was on Card . . . show #233 .

    Changes by me to 0G is on Basic Power by setting Target and Limit mW from 80000 @ 89000 !

    Please understand that the Extreme power limit 1 is not an obvious relation to do with the Target and Limit. It seems to set some sort of "max" power that the card can draw under some condition, but this is undocumented. For example, on a 1070, the "14,500" seems to prevent the card from going past 125W, even when you set target/limit to 170,000 (170W). If this is increased from 14,500 to 16,200, the card can now go up to 150W. Sometimes it can go up to 200W, but in PUBG, I got "TDP Throttle : PWR" at 155W, with this value set to 16,200, even though Limit was set to 200W !
    I had to use the GTX 1080 value (19,200) for extreme power limit 1, then I could go up to 200W without throttle.

    These settings can also affect battery power's bios TDP cap (which is much lower than regular cap), even if (on adjustable instead of fixed setting), you set the regular cap (in MSI Afterburner, for example) to 115W on a GTX 1070 (Example-- Target: 151W, Limit 230W, 100% TDP in MSI Afterburner is now 200W. Setting 76% power in MSI Afterburner puts it back at 115W), on battery power, this should be 50W maximum. But with 19200, and 242000, 137600 (GTX 1080 values), even at 76% TDP, instead of being limited to 50W on battery, it may draw 65W, causing an EC enforced shutdown because it's using too much draw than normal on battery power.

    Anyway these settings are undocumented for a reason. Just using"preset" value is enough for these.
    One chinese user blew up his MSI 1080 because he used the 1080 Ti Extreme Limits values instead of the 1080 "preset button" values.

    There is a reason the limit is there on battery too, you could overheat and risk explosion/fire with the cells.

    Holy sh*t, and here I was about to make the same mistake, ordering from "upgradeyourlaptop".
    I have a P751DM2-G in need of a GPU replacement, and so far, none of the resellers I've contacted personally (HIDEvolution and Sager, so far) have the part number at hand.
    Is there a specific part number I need to look out for so I don't get a lemon?

    There is a cheapo black pcb standard MXM 1070 for sale on ebay in the 500$ ballpark, some people have used them, and they run fine, and no heatsink mods required, just bolt, mod drivers and go.

    Please share a link to one of them here, thanks.

    I ask because I see two variants floating around: A blue or green PCB.
    So far, can confirm Eurocom's "upgradeyourlaptop" sells the green PCB variant that's essentially trash.

    green pcb is rated for 90-110W, blue PCB rated for 150W, both by Gecube
