The 980m card I had is the one you have pictured. The card I bought (below, also available on ebay, new) is out of a GT73 VR.
I'm not sure if your being sarcastic but I have posted pictures of my computer turned on. Unless you think I took the sticker off another machine. If you need me to take my back cover off to show you the card in the machine I can.
The card is slightly larger down the one edge but has a purpose built cut out for the bracket to sit in. The extra piece in the top right does not interfere with anything. The heat sink is not identical but with thermal pads it fits fine.
If what you want is help to upgrade your laptop I'd be happy to help.
Hi brettsidford,
Finally! A photo! Now we can begin to compare apples to apples.
If you examined the photos that I shared in my previous post you should have seen that all of the 10-series MXM modules shown in them look very different from yours. They are much bigger and the dGPUs are located in a different location. Here is a closer view of the front and back of the NVidia GeForce GTX 1070 MXM:

I hope you can see that this will not work in an MSI notebook that is designed for a 9-series MXM. This is why I wrote what I did. The 1070 MXM shown above is, as I understand it, NVidia's reference layout. In the past MSI has used the reference layouts without modification. I could be wrong, but one reason why I feel confident this is true is because CLEO usually does the same thing and it is sometimes possible to interchanges MXM modules between MSI and CLEO. In fact, many of the MXM modules for sale on eBay are CLEO parts. I've got lots of experience with my GT80 (it has two 980M in SLI) and it would be impossible to shoehorn the above 10-series MXMs into it.
But after seeing your photo, it was obvious that MSI decided to "roll their own" this time---at least for the GT73VR (I don't know about the GT83VR). The MXM module you purchased from eBay is clearly marked as an MSI circuit board (Micro-Star). And it appears to use the same dGPU position and circuit board mounting points as the 980M, 970M and 965M use (they are an MXM 3.0b size). The only difference, as you noted, is that the circuit board of your 1070 MXM is a little larger in some places. Here is a closeup view of a 1070 MXM with a similar circuit board as you purchased:

I found the above module for sale on eBay and it reveals a very bad thing. First, it appears to be a pre-release "Version 0B" circuit board. Second, it has a jumper wire on the back showing that it had to be "fixed" to work. Who knows what other "bugs" it has. The MXM in your photo appears to be a "Version 1.0" which probably indicates it is a production model. The "very bad thing" here is that some unscrupulous sellers on eBay appear to be selling pre-production models without clearly identifying them as such. Buyers must be very careful.
Your 1070 MXM does indeed appear to be mechanically compatible with the GT72, GT72S, GT73, GT73S, GT80 and GT80S notebooks. The stock heatsinks should fit. Although I would caution most users to use a high-quality thermal compound rather than pads as you did because a good compound will perform better than pads and this will be very important for such high-performance dGPUs. If the pads were necessary because the heatsink mounting surface was not oriented the same as the 1070 dGPU, then I would be concerned about inadequate thermal conductivity in the areas where the heatsink mounting surface does not cover the corresponding area of the dGPU.
By the way, I also tracked down some photos of a 1060 MXM by MSI that is even closer to the 980M, 970M and 965M layout than your 1070 MXM. So I can confirm that MSI has created 10-series MXM modules for the 1070 and 1060 that would retrofit mechanically into a 980M, 970M, 965M notebook. However, I was unable to find an MSI version of the 1080 MXM.
That leaves only two remaining problems to surmount: BIOS and vBIOS. As you've already discovered, the BIOS is a problem and I doubt MSI will do anything to fix it unless they were to offer an "official" upgrade kit. Without official support, we're all on our own. Whether or not vBIOS problems would also exist is anybody's guess. Hopefully you can report it if it is. Perhaps you can get help with that question from NVidia directly.
You've raised some valid questions that I'd like to hear MSI answer. Since they created a 1070 and 1060 MXM that will retrofit into a 980M, 970M or 965M notebook, why don't they support it and provide an upgrade kit for it? Did they create a 1080 MXM that will retrofit as well? Are the bigger DC input circuit and AC/DC adapters necessary if you don't overclock? (My GT80 with two 980M in SLI uses a single 330-watt AC/DC adapter but a GT83VR with two 1080 in SLI uses a dual AC/DC adapter rig that outputs up to 660 watts. That's twice as much electrical power for a dGPU model that is "supposed" to be more efficient!!!)
Kind regards, David
