    Default New H81M-ITX fails to POST

    System (all new components):
    • H81M-ITX (Part Number: 90-MXGPN0-A0UAYZ)
    • Intel Core i3-4130T (Product Code: BX80646I34130T) (35W)
    • 8GB DDR3 1600 (Crucial BLS8G3D1609DS1S00) (Micron guarantees compatibility with H81M-ITX)
    • pico PSU (picoPSU-120 + 102W Adapter)


    Behavior: System powers up (lights LED and spins up CPU fan) for ~8sec, shuts down, spontaneously powers back up, rinse, repeat. No video signal is produced.

    What I've Tried:
    • I'm testing the system outside of the case, on a non-conductive surface.
    • I'm testing with just the CPU/fan, a single DIMM, power supply, and motherboard.
    • I've re-checked and re-seated the 20pin power connector, 4 pin CPU power connector, CPU fan power connector, CPU, DIMM, power switch connector, and power LED connector.
    • I've tried the DIMM in both slots.
    • I've reset the CMOS, including removing the battery.
    • I've tried replacement parts for the CPU/fan, DIMM, and power supply (replacement PSU was RAIDMAX RX-380K (KY-480ATX) ATX 12V) (380W).


    I continue to get the same behavior in all cases, which is why I'm now looking for motherboard support. Note that I get different behavior if, for instance, I don't connect the CPU 4 pin power connector, or power on without a DIMM.

    Additional Notes:
    • I've removed the hard drive from the equation for troubleshooting.
    • There are no video or sound card. Video is on board and supported by the CPU.
    • I don't have a case speaker, so no beeps (not sure if there's a header for one on this board anyway).
    • I don't have a case fan.

    Please list the P/N's for what you system comprises of. Especially that of the pico PSU. Refer to #1 in my sig.

    I've added part numbers/product codes to the original post, including that of the alternate power supply I tried.

    Thx for the adds. That you've tested using the RX-380K PSU rules out MY biggest concern.

    Hmmm, the BIOS chip in the middle of the board directly above the PCIe slot. There should be a white sticker on it with writing indicating the board/BIOS came flashed with from the factory. Assuming the board is new, not open box or used, and you yourself haven't flashed it, what BIOS is this MB flashed to?

    I ask as I see the latest NON-Beta BIOS, 1.30 Dated Sept 10 2013, states "1. Improve system compatibility." . Whether that's what's needed here in your instance is another matter. Unfortunately, "Improve system compatibility" is quite opaque. Also unfortunate is the matter of it not booting to the BIOS with which to flash from.

    You or a friend have any DDR3 with which to swap in and test? Other than this thought you've done what I'd have to troubleshoot. And yes, I double-checked that Crucial states this mem compatible, for what that's worth. Most time a good sign but what with the differences in BIOS revisions sometimes things go in the opposite direction as to compatibility.

    I bought this motherboard new from NewEgg.

    The white sticker above the PCIE slot says "H81M-ITX P1.10-15A".

    I've tried booting with two different DIMMS, but both are the same part number.

    BIOS revision you have there is 1.10, FWIW.

    I'd still ask a friend and test with a different stick of memory, compatibility statement or not.

    Failing different memory, well, I'd pull the CPU and look closely at the socket for contacts that might be awry.

    There might be one contact, oh so microscopically off. I can't tell if it's an issue, and I'm not sure what I could do about it if it were. I am sure that it came capped and nothing has touched the contacts besides the CPU(s) dropping straight down on them.

    To follow up... This was a motherboard issue.

    I've obtained a replacement ASRock H81M-ITX, and it works as expected.
