    For fun considering the debacles. Have a thread on the front page. Discuss your overclock, which laptop you're using, temps and performance gains etc.

    200/250 for me, Crysis 3 @ 71C on a Clevo P770ZM.

    My 980M arrived vBIOS blocked. Using PREMA's mod. I have suspicion the vBIOS locked may not have as much overhead as the previous? Don't know until others post their results.

    I haven't overclocked my 980m yet, i don't think i can on the new alienware 17, its locked out i think( haven't researched it yet). But if i can, ill clock this thing to death like I did in the 860m thread :)

    narrowed it down to somewhere between +300 and +350 Mhz on core, still fine-tuning...

    That's crazy! I'm stuck at +125/+110 on stock voltage if I want it to be completely stable in Unigine Valley - bah, what a lemon I have!

    thats with overvolting, of course :) at stock voltage my stable core clock is somewhere in the range of 150 - 200 Mhz... stability testing with 60 min. unigine valley at max. settings and resolution (2880x1620)

    For a 180W PSU, the maximum limit I should be aiming to stay under should be 210W on the power monitor, due to the 85% efficiency rating of the PSU - correct?

    Correct.

    I ran my cards at 1266/1500 , we will see if the power mod helps. If it does I may go for 1333/1600.

    No I bumped it to 1.1v when I had instability in longer star citizen runs.

    in your opinion, what would be the ceiling for a long term overvolt on the 980M? been playing around with mine lately and it seems like +100mV or +112.5mV is the sweet spot when it comes to max. stable clocks. above that and i actually get less stable at identical clocks, probably cuz the card just cant get the power to the core that it needs :p

    Don't go over 10% of stock voltage for a 24/7 overclock has always been my rule of thumb. It's served me well over the years. When I didn't adhere to it, stuff has literally crashed and burned. :p

    At a GUESS I would say that as long as temps are kept reasonable that voltage should not be too much of an issue. I worry more on the stress of the VRM system rather than the core.

    tru that, seems like whats holding me back is a lack of power headroom rather than core/vram instabilities. in any case, not planning to oc/ov the gpu anyways, uc/uv for everyday purposes and stock settings for gaming :) just testing the limits for initial benchmarks....

    Short bursts up to 1.2v is unlikely to damage anything too bad, I should get my cards back next week :)

    1.o5v for everyday is it too much?
    im playing 1320/1500 with that volt stable and max temps I seen are 64-67c
    very cooool I can say :)

    1.05v? That's lower than the stock setting on Prema's vbios of 1.065v. If you have 1320 at less than that, you've got an incredible card there.

    Tech Inferno has a 980M modded vbios for Alienware made by svl7.

    http://forum.techinferno.com/showthread.php?t=8560

    Keep in mind that using the mod voids your warranty should anything go wrong and the procedure to flash is different with Maxwell so read the directions carefully.

    Will this work on the soldered 4GB 980m version? He only lists the 8GB version which is the mxm card

    I don't believe they have a 4GB mod unfortunately. It's worth asking in the thread but I haven't seen one. :(

    Edit: I ran a Google search and svl7 says that the non-MXM chips are unlikely to work with a modded vbios.

    Will do , he has done this for me many times over the past few years so hopefully he is not busy right now . Until then , I look forward to the +135 core clock when Nvidia releases the next driver !

    Well prema made new vbios for 970m/980m?
    I can go like 10-15mhz more up on the core but I keep it down at 1320mhz for safety... :)
    what is new on the premas vbios?

    Are you using svl7s vbios right now?

    You responded before I could get my post edit done.

    Svl7 explains here that it's unfortunately unlikely to work - http://forum.techinferno.com/genera...ries-overclocking-versions-17.html#post117597

    Sorry for getting your hopes up, I didn't realize that was the case. I actually wasn't aware the 2015 wasn't MXM.

    There's not a new version that I'm aware of, just the original that runs my cards at 1.065v. I tried to undervolt and apparently nVidia blocked undervolting for some reason so I'm stuck at that voltage or higher.

    Tech Inferno in the Clevo forum but I thought you just said you were running it already?

    If you're at 1320mhz on stock voltage, I'd just leave it alone that's an excellent overclock.

    yeah, im a lil confused here as well @kolias.

    so ure running prema vbios at 1.05v core voltage? how does that even work? undervolting aint supported yet on maxwell mobile. also, ethrem is right, 1320 mhz on core at 1.05v UNDERvolt is insane :D

    guys remember that I have 970ms sli and not 980ms
    my volt stock is 0.993v playing game so I went up to 1.05v at that clocks :)
    yes im running prema vbios(the version one)
    (edit):I can go more up a little bit :)

    I recently started benchmarking with a bit of OC http://www.3dmark.com/fs/4296200

    I noticed that at 400mhz, it was unstable and somewhat artifacting on screen so I have to dial down memory.

    I will check with the unlocked vbios and see how it goes. O ther GT80s have reached over 15k.

    good cards you have there, my second 980m which is in my P771ZM now is a ultralemon² only has an ASIC of 64,5% and stock voltage of 1.075v and can only do about +60 on core stable @ stock voltage, my first 980M which was in my P150SM did about 1320Mhz Core in Total @ 1.062v and had an ASIC of about 74% if i remember. So yeah i can do 1300 with my 980m but not without putting 1.162v in it :mad:, but anyways i already phoned with the guy who bought my P150SM and i can change the 980M :p

    They're good cards but as usual I have high ASIC on both and the corresponding high heat output. I think my machine is cursed. Card 1 is 78.8% ASIC, card 2 is 72.7%. I've hit the 87C throttle point coded in Prema's vbios a few times when utilizing high AA settings on stock clocks. It could be a paste issue but considering how many problems I have had with this machine and the fact that they replaced all three of my heatsinks when I sent it in for the 880M to 980M swap, I would think that with them taking the time to do all that they'd do a decent IC Diamond paste job as well. I'm waiting for Prema to release a version of his mod that has undervolting added, I haven't tried svl7's vbios because I am afraid of soft-bricking.

    My cards are 66.6% for GPU1 and 65.8 for GPU2. I realized, my silly self, said +135mhz core and 350mhz memory when infact it is 175mhz memory. So in reality I am running at a max 1262mhz core and 1428mhz memory.

    I noticed both my GPUs show 1.062v when underload too. I am running on stock still with 25mv, but I was wondering, is +100mv necessary? It seems memory doesn't OC that well, so I will focus on core clocks mainly. I am wondering if Prema's are the way to go?

    Does Prema's work on MSI machines? I'm not entirely sure about that, I'd ask him about it before risking it. As for the voltage, it seems that +100mv or higher can be necessary depending on the core you're going after. I wouldn't run that 24/7, nVidia definitely weakened the power circuitry on the 980Ms.

    I know some users already have them installed and working. I want to push the system to the max only to see how far it goes, then I will OC to a comfortable level and let it there. I want to try to focus on core mostly, because it will give me better performance at 1080p. Maybe stock memory and 200 core could work well enough as a perma OC.

    Yeah the memory on these cards seems to be universally bad.

    Tell me about it, I just had a crash at +175mhz memory, after 5 hours gaming. Gonna dial it down to 150mhz and see if that is "stable"

    5 hours? You would think that an error would get caught way before that.

    It wasn't even a taxing game. After a while, I got a gray screen while the sound kept going, and then the game crashed, sending me back to windows.

    In those cases I'd lean more towards it being a game glitch than the fault of an overclock.
