    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?
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.


    #2 - Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

      what bios version are you on? maybe flashing to latest final or beta bios might get the corsair ram working

          Re: Z87x-oc and boot loop - bad RAM?

          is that ram on the memory qvl list? maybe its worth sending back for another make/model? it should boot fine tbh

          tried in second and fourth slot from cpu socket to front of case?

            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.

                  using latest beta drivers for the 7970? use displat driver uninstaller program and do a clean install of gpu drivers

                    Re: Z87x-oc and boot loop - bad RAM?

                    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.

                      Re: Z87x-oc and boot loop - bad RAM?

                      I now have both monitors working in dual setup.

                      Both plugged to displayeports. It seems the issue was cable/adapter related.

                      I had mini-displayport to displayport adapter which I removed and bought 2 new mini-displayport to displayport cables. All is well so far.

                      Hope this helps anyone having similar issues.
