    For M17x r2 the biggest problem is how to work at sli mode，i searched many posts,found the DifferentSLIAuto1.3 can fix it.my system is win7 64bit
    step 1 install 2 pieces of 670mx ,connect the sli cable
    2 enable Intel Virtualization Technology in bios
    3 mod inf,install nvidia driver
    4 copy nvlddmkm.sys (under C:\Windows\System32\drivers)to the differentsliauto1.3 folder,run the differentsliauto1.3, click patch,run install.cmd restart the computer,go to nvidia control panel and open the "sli/phyx" window,click on "maximize performance", reboot
    mod inf&differentsliauto1.3 download links http://www.komeil.com/blog/nvidia-driver-windows-7-laptop-modded-inf
    https://github.com/EmberVulpix/DifferentSLIAuto/releases
    PS:almost nvidia cards （on m17x r2 or other latop cann‘t sli ）will work fine in sli by differentsliauto1.3 ，or even two different cards（i haven’t try this）
