    The potential throttling issue is the reason why I am interested in replacing 680M SLI with a single 980M as that should be good with 330W even OC'd.

    yes, they're undervolted so it's impossible for them to over-draw power

    Hmmm, while not likely, do you think it could be your PSU is on it's way out?

    No. nVidia has crappy driver support for anything pre-Maxwell. Maxwell will go the same way soon now that Pascal is out and about.

    So after a while, all you guys are using this trick to be able to use recent Nvidia drivers or did you go back to old Nvidia drivers?

    I'm using the latest driver in conjunction with this trick. It's only tedious if you end up with Display Driver Failures and have to restart as the trick needs to be reapplied every time.

    thanks for the feedback Vulcan. Those DDF happen often? what causes them?

    Other users of this trick?

    No, they only happened because I tried running to much frequency on the core, i.e. +149 (1275Mhz) vs. the +136 that is currently very stable.

    Let me know if you need help getting the newer drivers to work, you will need to modify them with a .inf file as there are no official drivers for 980M in the M18x R2.

    Also, if you've yet to do so, I HIGHLY recommend Prema's vbios, I picked up 1k points GPU in Firestrike with identical clocks simply going from the default vbios to Prema's.

    You can expect about another 3-4C higher peak load temps though so have that aggressive Hwinfo64 fan algorithm ready! Also don't forget to elevate the back of the laptop.

    Also I didn't discover this until recently but any hotfix driver will work without modding. But if you can use @j95 awesome drivers that is the way to go.
