    Yes because that model probably switches dynamically from one graphic card to the other without rebooting. You can check on Device Manager if both Display adapters are available at the same time. On my GT73VR I need to reboot to switch between integrated and nvidia. There's a physical button for that that yours doesn't have, or alternatively do it from the BIOS if you unlock it:

    I enabled the option, but it just let me pick muxless, so I hide the option :p
    Also how to increase the 45W power limit? Is this option?

    If I want to set it to 50W ,i should input 5000 ,right? And Im guessing the PL2 Power is the turbo boost 60w limit?

    The guide was really well done, with pictures and appropiate explaining.

    PL1 and PL2 values above 45W (62w for PL2) are IGNORED on all 7700HQ processors via both MSRs and MMIO's. You can **NOT** exceed 45W PL1 for longer than 28 seconds. PERIOD. End of story. Good game, well played, no rematch :)

    You can trick the CPU into REPORTING it is using less power than it actually is by changing IMON SLOPE in the BIOS to a value LOWER than 100 (100 = 1.0x).
    I tested this on a 7820HK I TDP locked to 45W manually and it worked. I haven't seen anyone try this on a 7700HQ even though I've mentioned it many times. You can combine this with changing IMON OFFSET to negative 31999 (-) with IMON SLOPE=50.

    Hey Falken :)
    I get it, so what about increasing the 28 seconds? Thats locked too?

    I have a option in the BIOS named "IMON Scaling support", even if I enable it, it doesnt show any window to change the value:

    Where is the setting supposed to be? Been browsing the BIOS but I cant find it.

    IMON scaling support-never saw that do anything, oddly enough.

    I found IMON SLOPE. What would be a safe value? 90?

    Also,do those options do anything on a locked CPU?

    There is no such thing as an unsafe value. You can use anything you want.
    Experiment and do whatever. I have an unlocked cpu so i can't help you.
    This setting isn't something dangerous like voltage.

    *Its the option ins this section, right?

    Power & Performance --> CPU VR Settings --> Core/IA VR Settings

    *And about BCLK overclocking ,is it possible? Where can I find the setting? I wanna try a small overclock, like 102

    *Intel Speed Shift is disabled by default. Should I enable it or keep it disabled?

    Don't bother BCLK overclocking unless you want to live dangerously. It's as dangerous as RAM overclocking. need MEMtest86 on flash drive boot to EFI, and do 1 loop to make sure you don't destroy your entire operating system. If your bios has an "OC" section you change the BCLK right there. if not, you're screwed.
