    Thanks mate.... I felt something like that can be the case... As of now Ive tried (and I hope my speakers didnt blow up from allnthe error beeps in pre-boot blackout screens):
    In legacy, and in pure uefi with win8 fast boot/secure boot both disabled, all possible configurations etc, 8 beeps, only SG works to startup the 980m...

    You would suggest perhaps different vbios can potentially fix it?

    Thanks

    Run 3dmark firestrike or 3dmark11 so we can see performance.

    Loading... Although I must note, not all games starts now since upgrade, i.e. star wars battlefront 2 wont start, Quantum Break wont start, it may be incompatible driver or something, its beyond me, using latest driver (modified ofc)... It all ran real well @680m in sli ,will post results soon ( if they run)

    alright here are the results and load meter stats , etc , Ive reset monitors for each test to have better outlook

    cinebench + Firestrike on default preset :

    and this is unigine heaven 4.0 at standard HD Extreme preset (windowed mode) , I think its pretty bad, seen online people get 3-4x times this score with same card on same preset.

    can anyone enlighten me, are mod vbios for these 980m cross-flashable? i.e. 8gb vbios to 4gb gpu, different brands. I feel its mostly to do with the card itself or with the vbios... before any driver installation it already reports PCIe @ 4x, unless its VBIOS , great, if theres a mod for it, its just ideal exit strategy...for now, Im mindfkd

    You should be getting around 9800 graphics score I think for 980M in FS.

    This in in a Clevo so it's higher than what you should be getting: https://www.3dmark.com/fs/17969094

    My 1060 in my M18xR2: https://www.3dmark.com/fs/14224321

    680m SLI: https://www.3dmark.com/fs/17969094

    780m SLI: https://www.3dmark.com/fs/19775350

    Those are stock runs (Don't remember if 980M run is stock but it's the lowest score I found by me)

    I never really found the 980M to be a good option in the M18xR2 due to issues. However, you should be scoring over 9000 (LOL, DBZ joke but actually true).

    Have you tried the hibernation trick?

    I'd try this and see what happens: http://forum.notebookreview.com/threads/alienware-m18x-r2-with-980m-possible-throttling-fix.791358/

    Don't cross flash 4GB vs 8GB vBIOS

    Thanks for the intel, when time is scarce help like this is much appreciated! A+

    Nope, I havent tried hibernation trick.... i think Ive hibernation disabled all together, 32gb ram aint exactly easy on hibernation :D

    I must look in to it. But with today's schedule I cant see doing anything about it until tomorrow morning... Overloaded with work and projects.

    Thanks for the tips and findings

    this was few days ago, as far as I got with stock vbios which was the only one not clipping 980m every 5 seconds, but OC was severely limited just to +135mhz, and that was ran with +135 OC on the core... have a look, but yes, I feel its under performing still

    This is better but it is still low. You should be getting around that score at stock speeds not OC.

    Maybe @Raidriar or @Mr. Fox know if the 8GB 980m vBIOS will work on 4GB 980M. But I am pretty confident it is not cross flash-able.
