    That baby Clevo would make a PERFECT Occulus Rift companion! But personally 15" isn't big enough, and is one thing I like about the M18x R2, it's hard to find an 18" display nowadays.

    Anyone here willing to take a guess as to whether or not GTX 1080 will be produced in MXM board-size?

    1070 will probably be the successor to 980M.

    I can't find any evidence for 1070 / 1080 being produced in the mobile format other than Nvidia's public statement that they have discontinued to mobile / MXM line altogether.

    What I meant. *If* 1080 come in mmx..., The 1080 graphics wouldn't fit in ordinary mmx slot(to big - same as older 980). Perhaps 1070 will fit if the card come as mmx.

    I got it because it was little. It has definitely taken some getting used to and I don't think I will every buy anything again with less than an 17 inch screen. It's a nice little beast, but I hate small form factors on almost anything. Humongous and heavy is definitely ideal as far as I am concerned.

    980M has to be pushed harder than most people want to push it for VR. It takes more of an overclock that what is possible with stock voltage to match a desktop 970. It would only work in a machine with outstanding cooling, otherwise it would be cooking itself.

    A small update was made to the original post. Anyone can collaborate and post results. Just change your PEG reset time from 100ms to 300ms from the advanced menu, inside the video configuration and "Pci express graphic".

    I have this exact same problem with a GTX880M on my m17x r4 (Win 7, driver 365.10 desktop. Tried a lot of different drivers but it didn't made any difference),
    My clock goes down to 135/405mhz for a few seconds and than back to normal repeatedly.
    Increasing the power limit on the vbios did helped at the beginning but it may just be coincidence, maybe it was the fact that i was booting after flashing the vbios with DOS
    I've also purchased a wall watt meter just to find out that it throttled even with 160-170w usage and low temps

    Today after finding this thread I've tried the hibernation trick and it worked perfectly after that
    I've done it two times and the result was the same:
    Cold boot, start Fire Strike, wait 10 seconds, throttling to 135mhz.
    Hibernation, start Fire Strike, completed the stress test two times without any throttling. This is great!

    I've also tried the PEG reset time to 300ms but it didn't made any difference.

    Definitely an Alienware issue. Glad to hear the same workaround for 980M helps your 880M setup.

    I tested 880M (x1) in the P750ZM and 880M SLI in the P870DM-G and had no issues with throttling at all. I was even able to set some 880M SLI world records.

    Here's an update to my previous single 980M scores posted above.
