    Yup, and higher ASIC really isn't all that like some people think. 980M was a nice upgrade for 780M owners, but NVIDIA seems to like gimping stuff to make things look better on the next upgrade and not have to try as hard to compete with themselves.

    Mr. Fox I've also read about your failed 980M card which was alive when it had a MOSFET replaced. Next is So if my card is getting hotter by this Prema mod could be happening but Since I hadn't noticed this with the same game back when I ran the card with Prema vBIOS only, So I can add the Tbonesan's point to this maybe the heatsink is gigving out the issues but afaik Alienware heatsinks are good quality, also to say with that slight OC (both the Prema, woodzOC vbios) the card is hitting limits basically regarding the driver I ran 362.00 and then the 369.15 that's all nothing more or less drivers thus Premamodv2 only (I understand that AW17 can't make the 980M work like in the p77xDM/ZM idk what's the case, that's another flip-side of the AW mess)

    Further if the 1.065 is too much for my card I think I can't get this high leakage card to OC well I guess If it's the MOSFET fault, Do these MOSFETs die out so quickly ? Then Nvidia is running an Abomination and people who are running stock everything don't even know that their HW is gimped to core and the BGA is just DOA, AMD can't compete at all now I'm afraid this cancer is spreading very fast from the Green greedia corp, Mobile spectrum is really weak with all these factory gimping, Pascal unstable clocks, high temps, DPC latency, Fan failures on Scammers editions, Overpricing, Omg, these guys are worst than that Micro$lot,

    Also Am I only one experiencing the blackscreens on 85C mark ? Or every 980M does exhibit this behavior, I don't get if they do how people manage to cool this beast and OC it. I'm not an Overclocker but curious and long path to OCing for me, Excuse me if these are stupid questions.

    Gelid GC Extreme paste only, Also to mention before it was 64-68C on Dota2 with same ambient and with AC a 2C less that's all and now It's topping only at a 60C with Dota2 same settings just the voltage is less now. I can remember one thing on the day I had the card with the stock AW17 1.6 CFM fan I was getting an 80-83C with Remember Me, old game immediately I changed the fans from the M17x R4 which is 11.4CFM, dropped to 70+Cs.

    I see. Test out Evolve Stage 2 and see how it works. Run a 120fps limit. If you're hitting 85c in a match something's wrong, definitely.

    The last version they released, was for windows 10 AFAIK, and they held back from updating for ages, until finally updating that too. You might need it. Latest I mean.

    As for your issue, check your contact to the heatsink, maybe check the entire card, do a full inspection. Try a different card and compare the results. There has got to be something we can put our finger on here.
    Like, why are you having these issues and no one else ? (don't get me wrong, many many people have issues, but if i start listing whats the most common cases of issues, it would be like I'm accusing you of amateur mistakes, so I will skip that part)

    Anyways, when overclcoking every card is different, but you need to clear the way power wise for your system. Clean power from a VERY good modulated sine wave breaker and powerbar, cool temps, a small portable freezer with the rack and an extra thick rubber extension cord, some experience using CLU too, maybe even a pro- copper shim job, a TEP module under the card or a copper backplate making contact to the chassis with thermal pads on BOTH sides of the plate AND both sides of the heatsink ( to slowly cool about 1C extra into the chassis of the laptop..every bit makes a difference right)

    don't forget the cooling on the voltage regs and the mosfets on the motherboard too, those affect your OC BIG time... the more efficient your power coming in, the cleaner it is, the less heat you will produce and the longer your components will last too. The PSU adapters for these laptops are ****. Don;t think they give very good clean power, because they really don't, they give worse a cheap PSU gives you at best no better then a Bronze would give you.

    I reached the 85 mark before but never had blackscreens. As for the temps, summer here in Germany is very hot and AC is nonexistent so with any modified vBios whether it is SVL7 or Prema the card is running in the 80s for seriously heavy games like battlefield and witcher 3 and 50s-60s for low demanding games like diablo 3 and LoL. SVL7 vBios is stable for me on all driver releases, not sure about Prema's stability with drivers as I found that the temperature hit from that vBios to be very huge compared to the lower voltaged vBios of SVL7 so I ditched Prema's very fast.

    Running @woodzstack vBios changes the above situation completely as the card never reaches the 80c mark at all due to some sort of dynamic clock modulation or if you would like to call it intermittent throttling :D . Personally I didn't feel the impact of such throttling while playing (Didn't have stuttering or lag ...) So eventually I decided to use the stock vBios till one day the time comes when the 980m is completely obsolete and really needs to be pushed with a modded vBios to get these extra frames but atm. I don't believe you need to.

    I tried this card with every non metal thermal paste imaginable and diff. types of thermal pads ... Thermal delta between all of the cases is minimal to almost nonexistent ... I would recommend that you flash the stock vBios and have a long gaming session and see what happens.

    I've reached 92C and never black screened, it's definitely not a good sign.

    I changed it, 92, not 94. 94 was the 880M.

    Ran Evolve Stage 2 just now, 2 bot games one as monster and one as hunter with maxed out (normal SMAA - monster then TXAA - hunter, FOV - 90 on both) and started at 70s and ramped up to 80s and It blackscreened again at some post 83-84mark :( FPS was fine at some 70-80's..

    With 1.000v vBIOS, Is the card failing ? I tried 2 repaste jobs as said it in first post and the heatsink was tight to remove as well due to the thermal paste, no chance of low pressure because the Clevo Xbrace needs tight pressure.

    Coupled with the battery issue, I'm in a huge mess right now, very unfortunate !!

    P.S : Ambient 71F

    EDIT : Idles at 45-50 (In Fans Auto since AW jacked up the EC, they will only start pushing more when 50C is reached dials back to 45 and repeat such a stupid botched job Dell programmers did, if manual at 2000RPM (no options either 0,2k,max this EC) it stays at 35-37 depending on the ambient, cannot use this because It doesn't help much with a constant 2k RPM as CPU needs more sometimes..Hotwell. Unfotunately another EC is not possible even with more granular RPM with single slider for both CPU and GPU because the GPU fan wont spin on both manual and auto with this Maxwell card)

    Ok, so yes. You're officially getting as hot as I am in a MUCH cooler, much less humid scenario with a generally much cooler card, running the SAME voltage (1v) that I am.

    Something is wrong with the cooling on the 980M. I suggest re-checking the heatsink contacts and the thermal pads on them. There is no way that my currently-unmodified (and thus worse) cooling, in my hotter, more humid environment, with a hotter card, is MAXING at the same temps you are getting shutdowns with, and ONLY in one game.

    I will do it, Ill get some prep pads, will do that work day after tomorrow with the existing heatsink and TIM and couple of leftover OEM pads. Ordered another heatsink too, I guess I should contact Eurocom for the bottom copper sheet they offer with thermal pads (Here at 1:41).

    Any signs of failure of the card from my given experience so far ? Others seem to have it past 85C without any issues...And prema's mod has 92C throttle limit on Maxwell too.

    @Solo wing , did your card blackscreened at 73Cs ? Can I know what's your ASIC ?
    Thanks.
