    Hey guys,

    Just picked one of these up. It has a 1070 and I am not going to buy a 1080 or a volta mxm gpu any time soon but where should I look?

    All the threads on here point to euro com and ebay and they're charging as much as the laptop cost me for the 1080mxm...

    I understand a premium being on a 1080 mxm but currently a 1080mxm is 2x the cost of a 1080ti. thats insane.

    I just want to be prepared on where to look for upgrades when I want to.

    I found a 1080 for 800 bucks in china. Still way over priced but thats a premium I can understand considering desktop versions got for about 60 percent of that. I really hope volta doesnt have these wild prices/ is compatible with the gt 73 titan...

    You can get the 1080 MXM card from one of the Chinese internet sellers like aliexpress or banggood. Probably best to use a taobao agent if you can find it on taobao directly. However you need to be aware of two things:

    1) The MSI 1080 has more than one layout. Make SURE the one you buy matches the layout for the GT73VR!
    2) The 1070 heatsink and VRM sink is NOT compatible with the 1080. You will need to buy the GPU heatsink and VRM sink assembly somewhere else. (if you DO find a place to buy these, legitly, please tell me where you got them because I might want one too). MSI has been all over form factors. The GT72s 980m needed a slight modification to use a 1070 for the heatsink to work, and the 1070 used in the GT72VR is a different format than the 1070 used in the Gt73VR. And the 1080 uses a different form factor too.

    At least he MSI GTX 1070 in the GT73VR uses a 'standard' form factor.

    I know that. I have the exact same thing. My 1070 is TDP modded to 185W.

    This is the card you have:

    This is the GTX 1080 in the GT73VR 7RF:

    As you can see the 1070 heatsink and VRM sink will not fit this layout.
    You need the 1080 heatsink and VRM sink.

    Fun fact: the MSI mainboard is 100% identical. So is the Bios and EC firmware. Only difference is the video card.

    If you buy the 1080, you will ALSO need the power connector for it. The 1070 does not have one. I suggest you make 100% sure any source comes with that power connector. While the 1070 can run at 200W without it, I do NOT know if the 1080 can.

    Piece of advice: if the 1080 is going to cost you $800 or more, don't even bother buying it. It's not worth it. Instead, spend the $50 and just TDP mod your 1070
    All you need are 1) replacement 1mm arctic thermal pads, 2) Grizzly Kryonaut or Phobya Nanogrease Extreme (you can use Liquid metal but you need to follow all precautions, kapton tape or nail polish over the SMD resistors and then use the "Foam barrier" trick on top of that, 3) Pomona 5250 IC clip, 4) 1.8v adapter (required), 5) Skypro HW programmer 6) male to female cable jumper assembly for connecting the Pomona clip to the 1.8v adapter. (Like this: https://www.amazon.com/gp/product/B01DC74A9Y/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 )

    I would not go past 195W TDP directly through the MXM slot. The 1070 card is capable of handling 250W (!) for benchmark runs, but only the Clevo has been tested (by @Khenglish ) to be able to deliver 258W of power directly through the MXM slot. The MSI MXM slot is electrically rated up to 195W of burst power, so I would not go past it I've used 185W on mine and left it running for hours with no problem.

    You won't get 1080 performance with 195W TDP+overclock, but you will get VERY close to it, for a fraction of the cost. A 185W GTX 1070 running at +180/+600 (Core/RAM) can score 21500 in Firestrike Graphics test. Not far from lower end 1080's. A lot cheaper this way, you won't have to worry about heatsinks and VRM sinks, but you WILL need to buy the Delta 330W PSU. The PSU will be the most expensive part of a TDP mod upgrade. You will ALSO need to use a program called "RW Everything", and go to the 'EC' tab and go to hex offset E3, and change the default value there from 90 to 91 (this sets the power limit at 330W, a GTX 1080 power system ID. Failure to do this will cause CPU throttling if you exceed 230W total system power). You must do this every windows boot. You can write a batch file to do it for you, which I can explain about later.

    P.S. I don't think ANY MSI user has TDP modded the 1080 video cards. Only the clevo owners have. Most people who are modding are modding the much cheaper 1070's, as they are very robust cards (the clevo is slightly more powerful) and can handle much higher TDP than default. The pascal editor has a 258W preset for GTX 1080's, but it is unknown and untested what will happen if you exceed 330W system power with the 1080 power ID. Exceeding 230W with the 1070 ID will cause CPU Power limit 2 throttling (overriding the settings in the Bios), but 1070 users have the 1080 power ID to take advantage of in RWEverything. 1080 users do not have a higher power profile (Unless with SLI, and SLI (power x2) does not seem to be set via the EC directly and no one has tested >330W AC power draw on a 7RF/6RF. If going past 330W will cause CPU power throttling to 45W (and then 25W), then TDP modding the 1080 will get you nowhere. But again--no one has tested this yet--only on Clevos, which can draw unlimited power with Prema mods.

    This is some really cool info. In all honesty, since you can sell the 1070s for around 600 or more id probably just sell my 1070 and buy the 1080. But I am expecting a year or 2 at least with this 1070. Next upgrade will be a tigerlake or zen 2 laptop.

    I was hoping the mxm gpu system would be similar to desktops with a slight premium. I am a bit disappointed there.

    Where can you get the power brick?

    Wrong pin size. Correct PSU but wrong pin. It's a 4 pin one. You're best off ordering it from a MSI reseller directly. It may be available on ebay but I didn't see it on amazon.

    The pads work although I bought the 145 x 145mm one.
    Grease and paste are correct.

    The programmer is called a "Skypro USB Programmer" and you need the 1.8v adapter for it too.

    The jumper cables I linked let you hook the pomona clip directly to the 1.8v adapter. You should read the pascal editor thread fully also.
