    ok ty for answers. Too bad for 2080 tho.
    The 2070 v2 in this laptop is 115w tdp right ?
    With good undervolt, what is the sustain frequency under load we can expect ?

    The performance is in the same range as the old 2070. If you need the 2080, I would wait on the X170SM or try to find a P750TM. It sounds like you are fine with less CPU performance if you are looking at the 3300X, although I would atleast get the 3600 if paired with the 2070 honestly.

    Yes actually, as i play on 4k/60 gsync screen, i don't need this cpu power at all, and i'll always be gpu limited. As for the others laptop you mention, prices are not the same :D

    Hi everyone, I tried lowering the SoC power usage today and have some good results.

    At stock, my SoC was always consuming 16-17w on idle, according to Hwinfo. That was leading to an idle PPT 30-35w even when the cores were sipping a couple watts.

    Today I tried using Ryzen Master to undervolt the SoC. There are not many people online talking about undervolting this. I found one user saying that 0.95v is sufficient. However, the system auto sets it to 1.1v. So I kept lowering my voltage by 0.25v until I got to 0.925v on SoC, which led to crashes. I moved it back to 0.95v and it seems to be running fine.

    Here is the setting in Ryzen Master:

    Surprisingly, although changing this setting requires a reboot, on further reboots the manual voltage holds. Awesome! But also somewhat concerning - what happens if we undervolt too far? I was able to bump this back up to 0.95v before a crash, but what if Windows wouldn't boot? The BIOS isn't any help! Perhaps someone can advise.

    Here are the results. This undervolt has gotten rid of 4-5w on idle:

    Every watt helps on this system, so I think that's a great success!

    You should be able to clear it by pulling the main and backup battery, then hold the power button down for 30 seconds while they are disconnected. It is typically called an EC Reset, but it also wipes any stored values in the SoC.

    Thanks @win32asmguy

    Update: I had a random hard reset after three hours, so I'm bumping up SoC voltage to 0.975v

    Maybe 1v would be safest.

    Hi Brian,
    Did you go further with your tests or lowering the voltage?
    At what SoC voltage your system is stable(without resets)?
    Did you succeed lower the power consumption at idle?
