    Hi
    write an email to shop@up-board.org or better send a message to AlingWu on this forum.
    If you cannot contact them in this way please let me know I will try on my side (but its more complicated)

    Regards

    Thank you, I have sent you a mail and linked this thread. If you meant I should make a new thread about it here, then I will do that.

    Was suffering the same problem with my Kickstarter UP2. Trimmed the thermal pad so that it only covered the main raised part of the CPU and not the other surface mount components, then reattached the heat sink without over-tightening and for the first time it booted into the BIOS. Have managed to happily install Ubuntu 16.04, all with my 5V/4A power supply for now.

    @Warren
    Thank you! Performing surgery on the cpu thermal pad was the only thing that got my UP2 board to work reliably, unlike the "official fix." Had just about written off the darn board!

    Hi,
    I am a kickstarter backer.
    I got the same issue.

    Then I try run win10 with Funmark's GPU stress test (16/9 11520x2160) and no ABS plastic case.
    1. remove heatsink and two thermal pad (N4200 and another purple thermal pad)
    2. attached heatsink with N4200's thermal pad only (no screw, no bronze color stand-off)
    3. base on 2. Trimmed the thermal pad so that it only covered the main raised part of the CPU and not the other surface mount components.
    4. base on 3. Use fan let heatsink temperate down.

    item 1 : I am not share. It seems work fine but overheat.
    item 2 : win10 still unstable, random reboot system
    item 3 : win10 still unstable, random reboot system
    item 4 : win10 still unstable, random reboot system

    PS. The power adapter spec is 5V/4000mA when I received up squared II.

    I am very upset and no idea what to do next ? :(

    @JtagHJ
    Larger thermal pad maybe not thick enough? And you put the other smaller thermal pad back, too?

    @Brian Robbins
    Larger thermal pad maybe not thick enough?
    -> The pink color thermal pad thickness is close to 0.8t/mm.
    -> I tried 2.0t/mm(black) and 0.8t/mm(pink) with heaksink , screw, and bronze color stand-off . (see IMG_8663.jpg, thermal pad)
    -> The 2.0t/mm seems too thick. The system very unstable after boot.

    And you put the other smaller thermal pad back, too?
    -> no

    Thank you!

    update something.

    I use ADIA64 to measure cpu package power.
    The cpu package power at window 10 desktop about 1w~5w when boot finish.
    Then open Furmark's GPU stress test (16/9 11520x2160) .
    Sometimes system crash directly.
    Sometimes GPU stress test work.
    The cpu package power about 13w~15w when GPU stress test work.
    The Power Supply (5A/4A) pumping current output from 5w to 15w immediately.
    I am not sure if there is a problem.

    So.
    I use a 5V/6A 30W Power Supply. (see attach file)
    then
    1. remove all thermal pad
    2. put N4200's thermal pad only (Trimmed the thermal pad so that it only covered the main raised part of the CPU and not the other surface mount components.)
    3. tightening heatsink with bronze color stand-off (take care BIOS can boot)
    4. tightening ABS case screw (take care BIOS can boot)

    The CPU0~3 temperate about to 103'C when games, facebook, youtube, furmark (gpu test, cpu burner test), AIDA64 execute same time.
    I am not sure but it's seem work fine.
    Any idea ?

    Here is the Power Supply Spec:
    VENDOR : DELTA ELECTRONICS
    MODEL : EADP-30NB D
    INPUT : 100-240V~0.8 (800mA) 50~60Hz
    OUTPUT : 5V/6A

    add photo for test case.
