    I have decided to release my own 980M undervolted vBIOS, based off the original Alienware 980M vBIOS. I have thermal protection set to 90 degrees, forced stock boost clocks, and voltage locked to a maximum of 0.9810V. I have bundled it with Prema's nvflash and a batch file to flash the vBIOS (modme.bat). This is NOT Prema's vBIOS, it is my own, therefore it is probably not of the same quality and is subject to further revisions and improvements. This is for 980M SINGLE SETUP ONLY in the M18x R2. It has serious throttle issues in the Alienware 18. I have not figured out the throttle bug with SLI setups, but it does not appear to be an issue with single 980Ms.

    SLI testing pending in the M18x R2. Will try to figure out wtf is the problem with the Alienware 18 *sigh* another demerit against the Alienware 18.....why do I even own one still is beyond me.

    Flash at your own risk. Download zip attached.

    Chime in with your results.

    In M18X-R2 BIOS changing IGFX to PEG completely eliminates the throttling even using a low level CPU overclock(41,41,41,41) and only one PSU, so I think in this case there is something in system BIOS configuration causing it to throttle and a proper update could been fix it. Its a fact that Clevo machines that comes with a pair of 980M dont throttle at all so I think this inherent behavior comes from the notebook motherboard not the 980M itself.

    There is some slight throttle I couldn't remove like Prema does with his vBIOS, not really sure how to tackle it. It appears for 1-3 seconds, then manages to resolve itself in SLI mode.....not really sure what to think. You can try to flash to your second 980M (change batch file to show nvflash -i 1 -6 980m_UV.rom)

    You think this could work for AW17 without problems or throttling?

    Probably not since it shares the same platform as Alienware 18, but you're welcome to try and revert back to prema vBIOS if it doesn't work

    Any chance of bricking or mere throttling ?

    Shouldn't brick, I flashed on my M18x R2 and Alienware 18. Worst case is throttle, but you can revert to Prema vBIOS in that case. Just use standard flashing procedure.

    What is the ASIC if the GPU this vbios was tested on?
    The voltage is contant at 0.981 through all the pstates?

    My SLI has driver crashes when switching voltage.

    Working pretty good, temps are pretty good but power throttles at 99.99 Watts. That's why you see the 1-3 secs throttle when the cards touches that power limit. If you can remove the power cap limit this would be my favorite vBios.
