    Sorry, no on-the-fly-undervolt yet...

    @ ALL

    I have just updated the GTX9xxM vBIOS Mods to v1.1.1:

    - minor bug fixes (e.g. voltage slider on GTX970M didn't level on certain ASIC cards)
    - Updated nVflash Mod to v5.227 (proper W10 & mobile Maxwell Quadro support) THX @Mr. Fox for testing!

    I have also added GTX980M-G, GTX970M-G & GTX965M-G vBIOS Mods, so that people with g-sync models can now also ENJOY the unleashed power of their GPUs! :)

    @HTWingNut can surely share some of his nice results! THX again for testing buddy! :)

    Prema, I'm using your BIOS for the W230SS. Is there a reason that I cannot exceed the voltage offset by more than -18.8mv with Nvidia Inspector?

    In addition, is there a way to change the UEFI logo when booting up Windows from the Prema logo to the stock blue Windows icon?

    The GM107 (GTX860M/GTX960M) are already running close to the maximum hardware voltage which is 1.2v...more can not be done without hardware mods.

    I want to undervolt it actually. And in Inspector it won't let me go past -18.8mv, is that a hardware limit?

    Also, I've noticed that the fans go full blast despite the CPU and GPU running at around 55-60 degrees. Is there a way to edit the EC to give it more headroom before turning on to a high RPM? Something like 65-70 degrees for both?

    The card can not be undervolted on the fly, the slider has no functionality to go below stock.

    The FANs are regulated further by the Hot Key App. Set it to Entertainment or Power Saving mode and enjoy silence.

    Yeah, I normally have it on Entertainment. Running Unigine Valley benchmark, CPU and GPU are both at around 55 degrees celcius and the fan is very audible (the fan level just slightly under maximum. Same thing if I switch it to Quiet.

    Anyway to make the fans have a lower speed at that temperature level?

    That nvflash won't allow you to force flash other cards. The only one I've managed to get that does, is 5.199 ...

    I've made sure it won't allow cross-flashing as that would trigger a black screen issue on ZM systems and lead to nothing...

    Oh ok.
    So I used the older 5.199 nvflash. The flash went through but obviously I have the same old screen problems.
    Which are far worse on Clevo BIOS.

    FYI, the New bios seems to work well and my P670SG now runs fine with 2133MHz modules where it didn't with the old bios. Two thumbs up!

    Did you try to disable "Panel Self-refresh"? May help to get the card working on your RGB screen on that Alienware.

    Yeah, I've removed those artificial RAM locks on the new Mods. ENJOY! :)

    I can't find this option.

    It certainly isn't in the generated text file.

    Thanks in advance, Prema

    Bothers me that the fans are kicking in so loud despite the temperatures being very manageable.. no need for the RPM to be so high if they're in the high 50s/low 60s.

    Prema, is there any added protection in the vBios? My PSU keeps switching off on me if I run Furmark.

    Also, the voltage is now standard at 1.062v where before I had to add 175mV to get that. Is it a higher standard voltage now or just indicating higher on the same actual applied voltage?

    The vBIOS will switch the system off as a protection if Furmark, Kombustor etc are used because those software just destroy the chip.
    It is also written in the README file to avoid these software even with stock vBIOS.

    1.062v is the voltage used by the average ASIC score for GTX980M, that's why it was used for the Mod. If your cards ASIC is higher than 70.5% then it used less voltage on stock vBOS, if not then voltage was just throttled (normal for stock vBIOS to throttle voltage/clocks even without OC).

    So the 1.062V is actual applied voltage and not an indication difference, good to know.
    I know Furmark is badbadbad... I'll stay away from it, but the laptop doesn't switch off when I run Furmark, the PSU switches off. Can the laptop switch off the PSU? The problem however is that even 3DMark with a standard run switches the PSU off with a moderate OC of just 180MHz on both core and memory and a 50mV bump. Without the 50mV bump this OC won't even work where it worked fine with the old vBios...

    Any ideas how that could be?

    Your old stock vBIOS throttled and didn't really use the OC that was set for longer than a few seconds...

    Watt add up fast...maybe undervolt the CPU to get some headroom for the PSU or get a larger capacity PSU.

    I'm already running a 240W Dell PSU... This shutting down behavior is new to me, it didn't do that before. Is my PSU perhaps a POS? Maybe a 330W PSU would work then...

    Depends on the CPU model, a lower end model should work just fine at stock clocks with OCed GPU.

    I'll be spending the rest of the night re-benching my system with the new vBios. Luckily I have all my old bench results with scores so I can compare if an OC took in the past or not. Interesting to read though that before the system would simply ignore OC's and/or limit them by itself....

    Still, if a normal CPU OC (just adding the extra bins) and a moderate GPU OC already draws too much juice for even a 240W PSU.. How on earth could anyone OC properly on the standard 180W brick? Guess they wouldn't and that's why they gimped the bios...

    Edit: So far with a lower OC on the GPU than before a higher score than before.... and just bought me a 330W PSU, just to see where the limits lie...

    I didn't
    I didn't know there were clevo/sager systems that came with 180W brick, you could try the 330W

    Prema I need some help - I have two problems. First sorry for my bad English.
    I have Clevo P170EM (prema bios) + GTX970m (prema vbios).

    First problem - GTX970 in idle turning on and off - GPU-Z or OpenHardwareMonitor showing ON for 1-2sec and OFF 1-2sec and all the time on/off/on/off. When gaming/testing - working ok - 99% usage no problem. I try two drivers for 970m, changing energy settings in windows 10, clean drivers with DDU, reseting bios and before prema vbios other vbios one from shop - the same problem.

    Picture of CPU-Z and OpenHardwareMonitor :
    http://postimg.org/image/fhxs2s2f1/


    Second problem - I can't disable Vsync. All games and testers showing 55,9-60fps max. I try two drivers, vsync in nvidia panel enable/disable/aplication/auto.
    I see in 3DMark11/13 and Heaven benchmark 60fps max....

    Drivers for 970m I try - 355.60 and 353.82 from laptopvideo site. 355.60 was totally bad - can't start games (stoped working at start), then 353.82 - all 3d working but 60fps max and still on/off problems in idle like the 355.60. Driver for intel gpu - from windows and manual instal latest one from intel site (the same as windows build in - 15.33.38.64.4252 - only one for windows 10).

    My system:
    - P170EM 230W PSU
    - GTX970m 6GB
    - i7 3940xm
    - 4x8GB Kingston 1600MHz
    - Samsung SSD 850 PRO 256GB (win 10 64bit)
    - Samsung SSD 850 EVO 500GB (games)
    - Plextor SSD msata 128GB (copys)
    - WD Black 750GB - DVD place (others)

    I say 3d is working - I mean - I can play 3D games and using testers no problem on GTX970m but Vsync is always ON and I see max 60fps limit. So the nvidia optimus is working because it running 970m in games. But when I want to check score of 3DMark for example I see max 60fps and see bad score at end. I try to test them to check stability of new card and cooling.

    Yes exactly I am saying you need to disable or turn off the 3D for vsync to turn off and for max FPS go up higher

    Turn off 3D Vision.
    Then you can turn off VSYNC.

    How the hell does he have 3D Vision or 120Hz screen if his laptop is Optimus?!

    God, so many ppl dispensing bad advice here, I feel sorry for the newbie...

    I found solution - windows 10 is guilty and drivers from nvidia.
    Back to really old 350.05 windows 8 driver - vsync on/off works fine and card not turning on/off any more. Games working, testers working.

    PS thanx for help octiceps...........you helped a lot.

    Yes they don't support that function at all on a hardware level.

    Just flashed Prema BIOS for my P650SE. There are a lot more options in bios now. Does anyone know if this model of laptop support Intel AMT? I see it has anti-theft support in BIOS

    Hey Prema,
    What kinda benefits are there for me to flash my P651SG-A? I currently have a T5X, it has an older firmware on the bios. Hoping to have it update and perhaps improve the stability of the laptop.
    Thanks in advance.

    Kind of a noob question: I know that the PSU has to be connected but what about the battery? Also, when it says to remove the PSU for 30 seconds before powering back if the battery is in does it mean you have to take it out as well?

    I would suggest taking battery out, and you don't need the battery to be connected at any point during the flashing. However, what I do is I flash step1, then step2, then the laptop powers off, I remove power and battery, then hold down the power button with power and battery removed to make sure the EC really resets and all the power is out, then I just plug in power and turn it back on, although I have put the battery back in and plugged the power in, and that works too.

    Uninstall your Intel GPU drivers and NVIDIA GPU drivers, and maybe even consider running DDU for both. Install the latest Intel GPU drivers and NVIDIA GPU drivers, then see if that does it.
