    Can't wait :D ... I checked again my daily driver the SVL7 vBios and it goes way past 100W @1.000V voltage with zero power throttle, so I am 100% sure that power draw cap is responsible for the throttling.

    But interestingly enough, my stock vBios also has that same ugly power draw cap and it throttles at 100W too. Why do people throttle a 980m at 100W is beyond me.

    Wow, Will try this and Run Crysis 3 with the next version since the game pulls post 100W in most cases I would be throttling the whole game. +rep man for the good work.

    I guess the Nvidia's failure at keeping the TDP in check unlike the 780M might have got this vBIOS shenanigans xD

    Please note, it is for the M18x R2 only, I couldn't get it to work right on the Alienware 18, so it will not probably work well with the Alienware 17 either. I'm still trying to work out bugs, I'm working on zero knowledge so you guys are like my beta testers

    Actually tried it for an extended period yesterday on seriously heavy games, working as well as my stock vBios with much less temperature so honestly so far super good :D

    It sadness me to see how difficult it had become to tune your own hardware now compared to how easy it was in the days of old GTX7xxx and intel C2D.

    I tested it on my SLI. It seems the 'driver has crashed and recoverd' is gone since voltage switching is between these two smal values.

    I also run Fallout 4 for several hours and I noticed a 'weird' throttling.

    GPU0 dropped to 5% utilization and GPU1 was a constant 100% when I had the weapon drawn. When holstered both cards were at 55 - 65 % rate.

    Could be the game though....

    Temps were amazing. Never got over 70 even with lots of enemies around and stock fan tables!

    Keep up the good work!!!

    As I said in the initial post, there is a strange bug in SLI systems I haven't figured out, causing my system to crash the driver every 10 seconds or so when using this vBIOS, probably power related, but even that I am unable to figure out. That's why for the most part on single 980M, the throttling is miniscule if at all present under gaming (it WILL show up in benchmarks, 100% guaranteed). I played ARK for several hours with a couple times crashing, so I think 0.9810V is too small of a voltage, will bump up to 0.9870V and if that is also too low, I will raise it only back to 1.000V. I've tried adjusting the power limits but it doesn't seem to correlate well. I actually managed to make the power problem disppear, and GPU-Z shows full clock no throttle, but my FPS went to garbage....1/5 of what it is actually supposed to be. Still playing with this.


    If there is any benefit to it though, it is reduced temperature and voltage, hopefully extending the life of the 980M, as they like to kill themselves every now and then. My card ASIC values range from 69 up to 74, though I did have one at 65 that was absolute and total trash.

    Interesting enough I noticed that yesterday when I was heavily stressing my 980m using your vBios, the voltage went up to 0.9870 at some point

    My ASIC is 68 and 69. Though this problem with the driver crashing is gone with your vbios, the throttling is also not understandable. We knew before that throttling occured only on high load, now I noticed it around 64%. Wattage is also lower. It never exceeds 70w per gpu. I have't benchmarked the system, but will try later.

    Also will do a gfx switch to see if it is better.

    So many gimmicks in this laptop. You gotta love them.

    Result with no gfx switch
    http://www.3dmark.com/3dm/17471123

    Temps without fan control peaked at 76 degrees, Throttling occured at 100W power.

    Result with gfx switch
    http://www.3dmark.com/3dm/17471332

    Temps without fan control peaked at 77 degrees. Max power was 104W. No throttling.

    With Premas vBios, I have almost the same score but with 122W mas power and temps going near 80 degrees.

    I might say that your bios is behaving better. Also no driver crashes. I have revert the power from the control panel to adpative and installed everything from the drivers (physx, HD audio and GFE).

    If I could get Prema's vbios with 1.0v instead of his publicly available 1.050v vbios I would be totally elated. I love this card, and I love how it's putting out GTX 970 performance but for me I am fighting a losing battle with the temperature, which will get up to and sit between 80 and 85C constant. To me this is way too hot and there isn't really anything I can do, I already have the unit elevated, I have the fans at 4200 RPM, and I have IC Diamond on the core and Shin Etsu heat pads on the memory. Hwinfo64 is showing 140W total power draw. It's my understanding the heatsink was designed with 125W in mind. If I could dial back the voltage and limit the wattage to 120W, even if I lost a few FPS and a few hundred points in Firestrike it would bring great piece of mind if I could get my sustained temperature down around 75-80C.

    When I see 85C on my OSD while playing Fallout 4 I begin to get uneasy, especially with some members here, such as TrulyFatal, who have melted the motherboard in their M18xR2 at sustained 90C usage.

    http://forum.notebookreview.com/thr...t-take-heat-of-my-980ms.793008/#post-10281763

    Any chance we can get this vbios to behave the same as Prema's but at 1.000v / 120-125W? If it involves comparing tables and you need help with it I'm game.

    Correction: Prema's vbios is at 1.062v. I would like to try 1.025v and see what that does for the temperature.
