    Lightbulb Maximus VIII Ranger + SM951 nvme + Windows 7 64bit OK!

    I asked asus support if it was compatible but they were no help.

    So in case you want to know, this works

    I selected Other OS and uefi boot in the bios. (and cleared secure boot since windows 7 doesn't support it)
    Maximus VIII Ranger (bios 1001) + SM951 nvme 256GB + Windows 7 ultimate 64bit (i7-6700)

    I didn't do anything complex like I read on the internet to get it working.
    Installed from USB bootable, made it with asus tool for USB3 drivers and copied the extracted nvme drivers from here
    After loading the drivers nvme.sys nvme.inf the SM951 was visible in the list to install windows on.

    I can't get any smart info though?
    The temp is about 55°C (IR measurement)
    (but I'm planning to add a small memory heat sink on it, on the first chip close to the connector)

    I didn't use the MS driver fix I'm not sure if I still have to run it or not (I think not)
    (I read the MS nvme drivers default present in windows 8 and up aren't that good, so I used a samsung one)

    Test info: to check if the SM951 nvme and drivers are ok.

    The install is as legacy bios (The SSD didn't show as 'UEFI Samsung...' only 'Samsung...' in the bios.
    The temperature that I read (with software) from it is 39-40°C but that is the middle of the middle of the SSD module, the IC on the socket is 55°C.

    The boot time is a bit longer with legacy boot I assume, I got power button +18 seconds for start windows + 12 seconds for login.
