    Default Z87x-oc and boot loop - bad RAM?

    Hi,

    I've been having boot loop problems since I bought my Haswell system with the Gigabyte Z87x-OC.

    Gigabyte advised me that it may be a PSU problem as I had a Corsair 860 PSU which had known problems and kindly offered to 'fix' the board. As I was too impatient and did not fancy removing motherboard and then waiting and then another reinstall - I purchased a Seasonic 760W PSU. And the same problems.

    After some more hair pulling I decided to replace the RAM (Corsair CMY16GX3M2A1866C9B) with a pair of 2GB sticks from my old i7 system (TR3X6G1333C9). My system has booted up every time without the boot loop.

    I was hoping if someone could help me with a diagnosis.

    Is it.
    Bad RAM?
    Motherboard having problems with newer RAM (XMP etc. Have tried switching this off but the same problem)

    PS.
    Please note I did use this RAM when I had my old PSU and the problem still existed.

    Thanks

    Please complete #1 in my sig so that we here know what else your system is comprised of.



    We're talking two 8GB sticks that came together in/as one retail matched kit?

    Did you since last posting, ever get it to run at it's rated 1.5v versus the 1.6v you stated in your earlier post/thread?

    Have you ran MemTest86+ against the sticks as a pair and individually?

    No RAM is not on the QV list. I've ran memtest86+ with both sticks and no problems.

    Edit: Switched the 16GB corsair sticks from PC and server. Server had 16GB patriot DDR3 RAM. Will post back if there are any issues.

    I'm afraid I am getting the same issues with this RAM - so not a ram problem. The other RAM is working flawlessly in my server.

    I'm lost now. :(

    Update:


    I've had so many false positives that I'm taking this with a pinch of salt. Firstly all RAM I tried including the old RAM has resulted in boot loops.


    Right, so I decided I could not get to the bottom of the boot loop issue and to RMA the board. But thought I'd give it another go before taking out the board.


    Steps:
    1) I unplugged everything and removed all except the cooler/RAM. It boot looped.
    2) So I reset the CMOS - no boot loop.
    3) plugged in the monitor into HDMI motherboard - no boot loop.
    4) plugged the graphics card into the second slot and moved HDMI to graphics card - no boot loop.
    5) plugged in second monitor into DVI port - boot loop straight away. Edit: displayport not DVI
    6) removed second monitor - boot loop.
    7) Loaded optimized settings - no boot loop


    I've been running like this now since yesterday and there is no sign of boot loop so far.

    13.10 drivers - so one version behind.

    can it be a driver issue on the graphics card? The drivers are software and run in windows - I'm not even getting that far when it boot loops.

    Edit: I meant displayport being the problem not DVI port - thinking something and writing something else. sorry.
