Disclaimer: Upgrading/Mod/Unlocking/Overclocking is your choice and any damages or problems are your fault! Happy Gaming!!! UPDATED as of 23 MAY 2015 Please note I am not a guru and this is only what I have read and pulled together from many threads. I installed one 980m and am waiting on the heatsink for the second one. I must admit this wasn't very easy. (At least not for me) But the bugs are being worked and the Guru's really deserve thanks! (and donations to keep the work alive. If you buy a $700+ video that isn't worth $200 without the support of these guys I don't know what to say about you) I will try to update this post with everything I have learned to this point so if you choose to do this upgrade you will have an easier (not easy) time. So far I am very happy with it coming from one 7980m! Guru's if you see anything incorrect let me know and I will fix it. Procedure for upgrading the M18X R2 with 980m’s 1.

(with 7zip installed, just rightclick and press "Extract to "/File name here"") Inside the extracted driver folder open Display.Driver. The "nv_dispi.inf" in that folder is what we need to replace it using NV_dispi.inf. 4. Unlock your GPU’s 4a. Disable the 980M in Device Manager 4.b.1.
