    With nvidia inspector my 980m's show 1.056 v. As soon as I open nvidia inspector and after about 7 seconds it then shows 1.000 v. And I have stock vbios 84.04.22.00.12 with no overclock or overvolt on the cards yet.

    Whatever voltage he's running, it's below the 1.2V limit. Desktop GM204 stock is over 1.2V.

    Pretty crazy that an OCed 1280 shader 192-bit mobile GM204 can match a 2304 shader 384-bit GK110 (desktop 780).

    I don't know, when they were reviewing the MSI GT72, the hwinfo screen had a max voltage of 0.887v after running 3dmark on the 970M. It's very well possible that's the stock voltage for those cards. That's why I want to see what kind of undervolt I can get with my 980Ms but nVidia has it locked in the vbios that you can't undervolt. I am using Prema's because I don't want to get into a situation where my system is soft bricked like happened with the 880M and svl7s vbios but Prema said he will remove the block in the next release so I'll patiently wait for that. Considering my cards will run 1297 on stock 1.065v, it wouldn't surprise me if stock core can run in the 900s totally stable.

    At 1126 core the voltage is 1.056v and at 1038 core the voltage is 1.000v. With stock 980m.

    this is for the guys that were in such a hurry to flash and couldn't remember.

    LOL give this man extended OC limits. He's already maxed out the core slider. :D

    [​IMG]

    1582/6000 at what I'm pretty sure is 1.187V, if the end of the voltage slider corresponds to 1.2V

    Dat idle temp...I wonder, how cold is it in the UK right now? :p

    Hopefully he doesn't post a video in a week about frying his card. I always try to get what I can with no voltage increase or a very minor one. What blows my mind is that the card isn't throttling from power supply limits!

    Yeah, the 180W brick definitely wouldn't power a 980M with that kind of OC, assuming it's even possible in the first place

    not with those on board ones. to get to 1400+ you need 125W+ of power, and only MXM cards have enough VRMs to supply that power

    It's more likely the BGA 980Ms are limited by the measly 180W bricks their systems are shipped with

    No it's not. Show me a GPU-Z or HwInfo Screenshot of a default bios with those voltages.

    Stock Clevo 970m voltage was 0.887v sometimes it shows 0.893v fluctuation.

    MSI vBios also had this as well.

    Prema unlocked vBios has a 100mV over volt for a default of 0.993v

    Yeah you're probably right about the 970M. I was thinking of the 980M, which is higher than 1v at default.

    Yes I think you're right on that.

    Do you think the 970m can handle voltages required to hit 1500mhz?

    I have my doubts long term.

    Who knows. For a 24/7 OC I personally wouldn't go over 10% of stock voltage even if temps are typical Maxwell cool. Benching it's OK to push it more.

    For 970M? I don't know. For 980M? I would probably not cross 1.1v with any daily thing. Hell, I'd probably leave the bloody 980Ms stock at 1127MHz if I got them for most gaming. Maybe 1203MHz if I really need it, but I'm more concerned with getting them for:
    1 - More powerful while drawing less power
    2 - Cooler cards, enough so that I could use the EM heatsinks
    3 - Better clocked CPU and more power available to CPU with single power brick

    ^that too, although it wont help you to get to 1500+ even if you have a larger brick

    Stock boost voltage is either .993 or .997, meaning two things, 1) not prema's vbios, and 2) over 1.2V

    EDIT: that was with prema's vbios.

    The number on the Inspector voltage slider isn't accurate. Sometimes it doesn't apply extra voltage until the slider is moved to the right some. You have to check actual voltage under load with GPU-Z or something.

    Hmmm how come core slider on kingsknight's 970M maxes out at +544 MHz but yours at only +405 MHz? You guys both have P650SE running the same Prema modded vBIOS.

    That's right, it's just about stock 780M SLI performance
    http://www.3dmark.com/fs/2535613 that's some AW18 user's bench from online. Even though it's only win 7, that is stock 780M with stock vBIOS and a single 970M is crushing it. It's not getting close to my OC'd performance, but since I don't have enough power to run my OCs 24/7, I might as well be using two 970Ms right now; I'd have a RIDICULOUS amount of power headroom (no need for extra PSU) and I'd be able to OC like there was no tomorrow on the 970Ms too.

    Why do I want 980Ms again?

    Anybody?

    Prema can mod that slider to whatever value you want. I just couldn't go much higher than that anyhow, so no point. He probably modded it specifically for that other guy.

    Asic 74.4%. Clevo 6GB 970m

    Seriously that other guy must have some magical 970m sample. I can get to 400mhz core but it requires a stupid overvolt that I'm not sure I feel comfortable running. How he managed just 70C at that clock and voltage is crazy.

    I got the same score in firestrike at +190 core +190ram at stock volts 970m with an Asic of 74.6%. I noticed that there is sometimes a drawback to pushing too far. It's finding the balance. I got 8568 or something like that with those settings. Mine was running auto fans and never went near 70 with those settings.

    Kingsnight is using the public release version of my Mod. Looks like I have to allow even more than 544Mhz for next update...LOL.

    HTWingNut has pre-release version as well as one with fixed OC as his daily driver.

    ALL my vBIOS use stock clocks and stock Clevo voltage unless the user decides to make changes.

    (The stock MSI vBIOS are undervolted compared to NVIDIA defaults.

    9950 score with 165/350 stock voltage. Can reach 240/400 with overvolt but I will avoid overvolting.

    Asic is useless. Has never been an indication of anything but to compare for meaningless number.
