    Hey there so a random but awesome thread here. I have a MSI GT72s model known as the MS-1782. I have been plagued with random power losses on the MS-1782 MoBo. I was able to pickup a MSI GT72vr MS-17851 V1.0 MoBo for a steal. The GTX1070 in it was dead but the motherboard was in perfect condition. I swapped the MS-17851 board into the chasis of my GT72s MS-1782 with zero modification. I used the MS-17851 heatsink for the CPU and then I used the MS-1782 GPU heatsink & VRM heatsink from the GT72s for the GTX 980m 8GB. Computer booted with no issues however it did not automatically install the drivers for the 980m. I disabled driver signature enforcement and downloaded the latest driver I could get to work possible which was the Nvidia 452.02. The next issue I ran into was that the GPU was downclocked to 405MHz clock and Mem clock. I was able to solve that issue by using Nvidia Inspector and manually setting the GPU to 1127MHz core clock and 1253MHz mem clock. Now I can fully utilize the GTX 980m in a motherboard that is was never supposed to be backwards compatible with. The last issue I am working on now is getting G-Sync working again as with my older MS-1782 MoBo I had 75Hz refresh rate and G-Sync. Currently I cannot load the drivers any newer then 452.02 and G-Sync does not appear as an option and I can only reach a max of 60Hz refresh rate even though I know my monitor is a 75Hz monitor. I've learned so much from the fellow enthusiasts off of this forum and I am glad to be able to share this to people who maybe are looking to fix their old MSI GT72s that had a faulty motherboard. For anyone who follows this any more advice to get later drivers to work and G-Sync back would be phenomenal. My board has the i7-6700hq CPU and I am using an MSI GTX 980m 8GB model GPU. Hope you all can also benefit from my research. You will have to modify the Nvidia Driver .inf file to properly be able to detect the GTX 980m and install it correctly otherwise it will only show as a basic Microsoft 241856224_10226240337731550_7766029211495561663_n.jpg 239103920_10226084431793999_3618634353036267991_n.jpg 239433100_10226084429193934_2422582667442255037_n.jpg 236928149_10226084429993954_5300171241974742235_n.jpg 239407222_10226084430913977_4153234182173524921_n.jpg display adapter.

    You will only get your GSync back with an MSI GTX 1070.
    the other way around is of buying a GTX 1070 and install it in the GT72s. This solved my powerlosses. Because the 980m cards are the wrongdoer.

    Was the issue with your old GT72s board the power IC? If so might get a VR board to replace my dead board too.

    Else the new chassis, battery and screen is going to waste.

    Yes it was. Also a new update today I was able to update to an even newer driver last night I am now running the 457.51 Nvidia Driver stable however still no G-Sync. Computer plays just like a GT80 Titan they only could do 60FPS as well. The performance is great. If you plan to do the same upgrade You will need the CPU heatsink for the newer VR board but your GPU heatsink and VRM Heatsink will work just fine. 242391327_10226284058544543_2106635968469615929_n.jpg 242440589_10226284059384564_655649646348560381_n.jpg

    I bought an entire parts GT72vr laptop. The only thing wrong with it was the GPU in it was bad (the 1070). It would boot with the 1070 but there was blue dots everywhere on the GT72vr. I robbed it of its motherboard and installed the VR board into my GT72s chasis and used my old GTX 980m. I am up and fully functional minus the loss of G-Sync. There was a lot of people with early model GT72s 6th gen's that have all kind of VRM/IC problems and the 2nd gen board (GT72vr) did not have those problems carry over so much.

    I take it you lost the ability to use MUX with the upgrade i.e to switch from iGPU to dGPU.

    Being that I had a parts laptop I used the switch board from the vr. I have not tried to switch between the iGPU and dGPU yet but I don't see why you could not. In the bios with it being unlocked there is an option to boot only from the iGPU if I wanted too.

    But it might be wired on the board for the igpu just because the option is in the bios doesn't mean the physical MUX switch hardwear is.

    Planning on replacing the board sometime early next year after I fully upgraded my clevo laptop.

    Well feel free to message me about it. I fully document all my builds/repairs so I have all the photos of it. I also know alot about the old clevos as well if you ever need help in that area.

    Here is a few pics of what it looked like together with the board you are speaking of. I know that the decals on the GT72s do not match the decals of the vr top case. You can see I used a few daughter/sister boards from the vr chasis in my s chasis. I did just end up keeping my touchpad and front LED's the s models ones. 239257190_10226084429633945_1624355134165483027_n.jpg 236928149_10226084429993954_5300171241974742235_n.jpg 239103920_10226084431793999_3618634353036267991_n.jpg

    Thanks, bud I have had the laptop completely disassembled to replace the entire chassis after a hinge failure took it all out.

    That's why I was going to replace the mainboard and the GPU it took out at same time as I have already replaced the screen, chassis, battery, fans might as well continue to replace everything else.
